How To Bypass O2 Sensor?

Your vehicle has a lot of different sensors to keep it running properly. One of those sensors is the oxygen sensor. In this article, we will not go in-depth on what the oxygen sensor does because if you are reading this article then you probably already know.

Your car has a couple of oxygen sensors, and each one measures things a little differently. What we will cover in this article is how to by-pass the O2 sensor.

The one that might need to bypass is the one after the catalytic converter. We will cover a couple of different methods and explain the pros and cons to each one, and we will also explain why you might want to bypass the oxygen sensor.

How To Bypass O2 Sensor

How to bypass O2 sensor?

Why bypass the O2 sensor?

Before going into the different methods, we will briefly cover why you might want to bypass the O2 sensor. Well, the main reason is to make sure your car will run properly if you don’t have a catalytic converter and that the check engine light isn’t constantly on.

Your vehicle may not have the catalytic converter for a variety of reasons. It might have fallen off, got a hole in it, or been removed for more horsepower, but without it, your car will always have a check engine light if you still have a functioning O2 sensor.

This can be annoying and also lead to other problems happening that is why it is important to try to get it to turn off by bypassing the O2 sensor.

Dummy Oxygen Sensor

A functioning oxygen sensor leads right into our first way around it, and that is to put a dummy O2 sensor in. A dummy O2 sensor is a fake one that does readings like a normal one.

A dummy one sends the cars computer the proper information that a normal one would send if it were reading correctly.

Dummy O2 sensors are easy to use. All you have to do is locate your cars current O2 sensor and unplug it. You then plug the new one in. It is that simple or is it?

Well, with dummy O2 sensors sometimes the cars computer can tell that it is a fact sensor and this will cause your car not to run right.

You will not get proper fuel mixtures and will lose power and fuel efficiency.

That is why if you want to go with a dummy sensor you will need to make sure that you get one that is programmed to work with the vehicle you have.

Also, buying dummy O2 sensors can be a challenge because removing your catalytic converter is illegal and the only reason why you would need a dummy O2 sensor is if you had done that.

O2 Simulators

Another name for dummy O2 sensors is O2 Simulators. An oxygen sensor simulator will send the computer the proper wavelengths. They work with resistors and capacitors.

Another reason why O2 simulators don’t always work though is that waveform is only one perimeter of a functioning oxygen sensor. When using O2 simulators or dummy O2 sensors, then you are likely to get a code for a known working one.

Also, these devices if you can find one can be costly because you need one that is made well. If you get a cheap one, then the chances are good that it won’t work.


If O2 simulators or dummy oxygen sensors don’t work the best, then what are some alternatives? Well, the main alternative is to connect a resistor to the O2 sensor that you already have.

The resister will send a single to the computer that the sensor is working properly. The reason that attaching a resistor straight to your current O2 sensor is a better method is because the one you already have a working sensor that you know is compatible with your vehicle. That means that you don’t have to find a sensor that is compatible.

The way you attach the resistor is like with the first method you remove the O2 sensor from the vehicle. Then you solder the resistor onto the connectors and then plug it back in.

It is pretty simple, and most people can figure out how to do it. The resistor doesn’t have to be a strong one. Just one that is fifty ohms or so will do the trick and will be able to trick the computer into think that the O2 sensor is working right.

Preventing Check Engine Light

These methods for bypassing the O2 sensor are for the second O2 sensor or the one that is after the catalytic converter. This is very important to remember.

You don’t want to mess with the oxygen sensor before the catalytic converter because that is the one that controls the fuel mixture in the engine and regulates things.

The second one is to make sure that the catalytic converter is working right and to let you know if it is not. If you mess with the pre-catalytic converter O2 sensor, then your car will run poorly.

Messing with the second one will not affect how your car runs. This is important to know because some people are misinformed and think it will.

Bypassing the Oxygen sensor is to make sure that you don’t always have a check engine light on. If you don’t mind the check engine light, then you don’t have to bypass the second sensor. It is good to though because you don’t want the check engine light always on or else you won’t know when something does go wrong with your vehicle.


Bypassing the O2 sensor is relatively simple, and there are a couple of methods on how to do it. The key is to trick your car’s computer to make it think that the catalytic converter is there.

You can do this by getting a dummy or simulator O2 sensor, but these don’t always work deepening on the type of vehicle you have and can also be hard to find.

If you do find one though all you have to do is plug it in where the original O2 sensor was. If you can’t find one that will work with your car though or want another method to bypass the oxygen sensor all you have to do is solder a resistor to the current sensor.

This will send a reading to the computer like your sensor is working properly. Bypassing your O2 sensor isn’t hard to do, and while it is illegal to drive without a catalytic converter, sometimes you have to do what you have to do.

How To Discharge Car AC At Home?

Most cars these days have air conditioners in them, and this is a nice luxury to have because it keeps you cool in the summer. If it is hot outside your window isn’t going to do much good, so having your car AC to rely on is a conviction that most people take for granted.

Sometimes though your cars air conditioning stops working and needs to be worked on or the refrigerant needs replaced. In order to work on the AC or replace the refrigerant, the old refrigerant has to be removed.

In this case, it is called discharging the AC unit. You may be wondering if you can do this yourself at home and if so then how. Well, after reading this article you will know the steps you need to take to discharge your cars AC at home.

How to Discharge Car AC at Home

How to discharge a car AC at home?

What do you need?

Before going into how to discharge a car properly AC, we will provide a list of all the things you will need. The main things you will need are

  • An Air Conditioning Service Machine
  • Refrigerant Purity Tool
  • Supply of HC-134A (if you are recharging your AC as well and not reusing old refrigerant)

The list is fairly short of what you need, but it is important to know how to use the tools properly as well. Proper knowledge of how to use the tools and following proper safety precautions is very important with this process.

Coolant is bad for the environment and you, so it must be stored and disposed of properly after being discharged from your vehicles air conditioning if not being reused.

Recharge your car battery is a good thing to do,the best battery tender is excellent choice to do that. Let find your the good one.

Steps to Discharge AC

The first thing to do to discharge refrigerant from your cars AC system is to determine if the refrigerant is pure or not. You don’t want to reuse bad refrigerant, and you want to make sure there are no sealers in the refrigerant which might tear up the server machine.

You test the purity of the refrigerant you will use the refrigerant purity tool. To do this, you will first need to locate the low and high-pressure ports. A lot of times there will be a minus symbol on the low port and a plus sign on the high one.

After locating the ports, you will remove the cap of the high-pressure port and connect the purity tester to it. This will pull out a small about of refrigerant and test it. If it is pure, you are good to go. If it is not, then other steps which we will explain in a moment must be taken.

After testing the purity of the refrigerant in the AC unit, you will then connect the air conditioning service machine. The way it is connected is by removing both the high and low-pressure port caps.

Then you will take the red line from the AC service machine and connect it to the high port. After you have the red line connected you will take the blue line and connect it to the low port.

Steps to Discharge AC

Steps to discharge AC?

It is important that you have the lines connected all the way because the machine is going to create a vacuum to pull out the refrigerant.

If the refrigerant was pure, then you can move on to removing it, but if it was not, then you need to add filters into the lines to prevent sealants and other things from going into the server machine. You don’t want things going into the service machine because it can damage it.

Once both lines of the machine are connected, you can turn it on. Notice to see if there are any pressure readings. There should be pressure if there is not then you probably have a leak that will need to be fixed.

Most machines are really simple to operate these days. They are automatic, and you just have to push a button or turn a knob to start it.

Once the machine is started, it will turn on a pump and create a vacuum which will suck the refrigerant into the reservoir tank on the machine. If the coolant was pure, then you can reuse it, but if it was not pure, then it will need to be disposed of properly.

After the machine is done pulling coolant out of the cars AC the pressure will have reached zero. That is how you can know if the AC is fully discharged.

It really is that simple to discharge your cars AC. Once you are done doing the repairs you needed you can use the server machine to add refrigerant back into the car as well. This makes the process really easy.

What not to do?

So, now that you know the proper steps to take to discharge your cars AC we will cover what not to do. The first thing that you should never do to discharge your cars air conditioning is to disconnect any hoses while there is a refrigerant.

That is because refrigerant is bad for you and the environment. It is actually illegal in most place to remove it improperly. Also, the refrigerant must be disposed of properly.

The next thing you should never do is remove refrigerant on your own if your area has a law that requires you to have an EPA certification to remove it.

Some governments require you to be certified to remove refrigerant from a cars AC. If your area is one of those, then you need to follow the law.


Discharging your car’s air-conditioning isn’t as hard as you might think if you have the proper tools. The problem is a lot of times those tools can be hard for an everyday person to get.

This is due some to the fact that a lot of areas require certification to remove refrigerant from a car because they want to protect the environment and make sure it is done right and disposed of properly.

If you can get an air conditioning service machine, a refrigerant purity tool and a supply of HC-134A, then you can easily discharge your cars ac on your own.

You now know that all you have to do is locate the high and low-pressure port, test the purity of the refrigerant, and then connect the server machine and turn it on.

The service machine does all the work creating a vacuum with the pump and pulls all the refrigerant out into a tank. Then you are done and have an empty AC that you can work on or replace with clean refrigerant. It really is that easy to discharge your cars air-conditioning at home.

Transmission Cooler Lines Leaking At Radiator: What You Need To Know?

One of the critical components of your car is the transmission. It is probably the second most important thing after the engine because if the transmission isn’t working right, then the vehicle can not be driven.

One problem that can happen with the transmission is that it might start leaking fluid, and this can occur in a few spots, but for transmission fluid cooler it will most likely happen at the radiator.

In this article, we will explain why your transmission might start leaking at the cooler lines, how to diagnose it, and also how to fix it. Read on to learn everything you need to know about your transmission cooler lines leaking at the radiator.

Transmission Cooler Lines Leaking At Radiator

What is transmission cooler lines?

Before going into details, we will briefly cover what the transmission cooler lines and radiator are. That way you can locate them easier when looking at your car.

The transmission is responsible for switching the gears of your car, and the transmission fluid goes thru it to keep the gears and moving parts cool and lubricated.

The cooler lines are the tubes or hoses that come off the transmission and into the radiator. The radiator is the ruffle looking thing usually right behind the grill of your car and will have fans attached to it.

It is where the coolant goes into to get cooled off before going back into the different parts of your vehicle. The coolant has to be cool to cool the other components of your car.

How to know if coolant lines are leaking?

So, now that you have a better understanding of what the radiator and transmission so we can move onto diagnosing if you have a transmission cooler line leak.

The first thing that you might notice is that you have wet spots under your car when you move it. This could be a lot of different things though, and your transmission fluid leaking is only one of them.

It could also be oil, condensation, or another liquid. That is why it isn’t a surefire way to know that it is your transmission cooler lines leaking, but it is an important thing to pay attention to, so you can know if you need to look deeper or not.

If you do see liquid under your car, then you need to investigate and see where it is coming from.

One way to investigate is to open up the hood and look under it. Visually inspect all the hoses and see if you can see any liquid coming from any of the connections.

Bonus: If you want to buy a automotive multimeter, this is the best automotive multimeter for you.

Most of the time the problem or leak will happen at a connection, but sometimes the hose itself will get damaged. To see if it is transmission fluid leaking you can check all the tubes coming from the transmission.

You can also check the transmission fluid level on some vehicles with a dip stick. If your transmission fluid is low, then it is a sign that it might be leaking. Sometime you won’t have a dipstick though, but can still look at the transmission fluid level in the reservoir and see if it is low there.

You might also be able to feel if your transmission fluid is getting low while driving the vehicle or hear if it is. This is because if your transmission coolant is getting low, then the transmission will most likely start shifting harder.

The lower it gets, the worse the shifting will get. If you drive the car regularly, then you should be able to feel or hear this. If you think your transmission is shifting funny, then it is a good idea to check the fluid.

The last thing that might help you know if your coolant lines are leaking is if the engine coolant is starting to get a reddish color. That is because the transmission fluid could be mixing with the engine coolant and that will lead to a color change. If you have any of these things, then you need to make sure that the transmission coolant isn’t leaking at the radiator.

How to fix Transmission Line Leak at radiator

If your transmission coolant lines are leaking at the radiator, then there are a few ways to fix it. If the lines are old, then you might need to replace the whole line. This is pretty simple. All you do is remove the old line and put the new one in.

This should solve the problem if the old line was leaking from damage. Another way to fix it is to put sealant on the end of the line where it connects. There are a variety of sealants on the market, but you want to make sure you get one specific to transmission coolant lines.

That is beaches you don’t want to damage more things by fixing the problem, and you need a sealant that can handle high heat.

If you don’t want to put a liquid sealant or can’t find one that is working for you, then you can also try adaptors. Some vehicles are prone to having transmission coolant lines that leak, and they have made adaptors to fix the problem.

You remove the line, put the adaptor on, and then put the hose back on. The adaptor is designed to fit the gap and seal it up. You can also use tape on the lines to help seal them up. A Teflon tape that can handle high heat is your best option if you want to go the tape route. There are a lot of ways to fix coolant line leaks at the radiator though, and most are pretty cost effective.

Just replaced the radiator.

One of the most common times to get a transmission coolant leak at the radiator is when you just replaced the radiator. This is because the hoses may not have gotten connected correctly.

When replacing the transmission coolant line or reattaching it make sure that you attach it right. Don’t cross thread it, which is easily done, because that will cause a leak. Also, if you have just reattached the hose and have a leak, then one last solution before anything else is to loosen it back up and jiggle it some and then tighten it back down again.

The problem might be something as simple as the hose not being seated right and the connection not being tight.

It is important to try not ever to drive your vehicle with low transmission fluid because it will cause significant damage to the transmission. That is why it is essential to stay on top of potential problems before they become more significant.

If you see liquid under your car, then you need to figure out what is causing it and fix the issue. If it is a transmission coolant leak at the radiator, then it is an easy fix. The way you can figure out if that is the issue is to check your transmissions fluid level, pay attention to the shifting, and check the coolant lines going into the radiator.

If you notice a leak, you can replace the line if it is damaged or add sealant or tape at the connection to tighten it up if the line is fine. Now you know how to find, and fix a transmission coolant line leak at the radiator.

Lawn Mower Won’t Stay Running: Why And How To Solve?

So, your lawn mower keeps dying on you. Well, just like anything with a motor, sometime your mower will have issues that cause it to stall and cut off. If you are having that issue with your mower, then you are in the right place.

In this article, we will look at the reasons why your mower might not stay running and also give you the solutions for them. Keep reading to see all the possible reasons why your lawn mower is stalling.

Possible problems

Before going into an in-depth analysis of each issue, we will list out the potential problems below. That way if you have an idea of what the issue might be you can jump to that section first to save yourself some time.

The reasons why your mower might not stay running can fall into the following areas:

  • The Fuel System
  • The Carburetor
  • The Ignition System
  • The Cutting System

1/ The Fuel System

There can be a variety of reasons with the fuel system why your mower might be cutting off. Most of them are pretty simple things and can be fixed easily. The first thing to check with the fuel system is the gas.

If you left gas in your mower for an extended time, then it might not be good any longer. It could have had water condense in it, or it could have evaporated leaving a varnish-like residue.

If you know you left gas setting, then drain the gas from the tank and also the carburetor, then you can add fresh gas. This might solve your problem.

Some of the other issues in the fuel system, which we will cover shortly, can also come about from leaving gas in the system, so it is a good idea to drain the gas if you know that you won’t be cutting for a while.

The next thing that could be wrong with the fuel system that can come about from old gas or happen on its own is dirt and gunk build up. Gunk and deposits can build up in a variety of spots.

The first spot to check is the gas cap itself. Remove the gas cap and see if the mower will stay running without it. If it does, then that means the gas cap vent is blocked.

You will need to clean it out, so air can get thru. After doing that the problem should be resolved. If something else is dirty though and the gas cap is not the issue, then you will have to look farther.

Sticking with airflow, the next thing you can check is the air filter. This should be clean and not have debris or blockage. Also, if it has oil in it, then that is a problem too. If it does have a blockage or is dirty, then you will need to clean it out or replace it.

Air filters are not expensive, so it is a good idea to replace with a clean one regularly or at least clean it out since it is easy to get too. If it is not the air filter that is dirty, then it might be the fuel lines that are dirty.

If that is the case, you will have to drain the fuel and then remove the lines. Remember to drain both the tank and the carburetor. When removing the lines inspect them and see if you see any build up. If you do clean it off or replace the lines.

2/ The Carburetor

The issue may be in the carburetor itself though. It might be the thing that is dirty. If you are draining the fuel, then go ahead and take the time to check the carburetor. See if you can see any build up of gunk or deposits in it.

If you do be sure to clean it. Also, remove the fuel filter from the carburetor and see if it is dirty. If it is then clean or replace it as well. Same as the air filter, the fuel filter is pretty easy to get to and is cheap, so stay on top of replacing it and making sure it is clean. This will keep other parts of your mower running longer.

When cleaning the carburetor, it is essential to do it properly. You should use carburetor cleaner and spray it down thoroughly. Sometimes though even the cleaner won’t be able to get all the build up off. This is because fuel residue can be hard to remove.

If you can’t get the carburetor clean, then you can rebuild it with a kit from your mower manufacturer. Sometimes though it isn’t worth it to rebuild. This may be because you don’t have the time or the skills to do it.

If that is the case, then you can just buy a whole new carburetor and replace the old one. No matter if you are cleaning, rebuilding, or replacing the carburetor be sure to clean out the fuel lines as well.

3/ Ignition System

The next reasons why your mower might not stay running could come down to the ignition system. This is similar to the fuel system and could be lumped in there. The ignition system for our purposes is where the spark occurs to ignite the fuel and provide power to the mower.

The part of the ignition system that we are worried about is the spark plugs. Old wore out, and dirty spark plugs can lead to the engine dying. They may work good enough to start the mower, but then misfires might start to happen leading the mower to shut off. If you hear misfires, then checking the plugs should be one of the first things you do.

To make sure the plugs are good you first need to pull them from the engine. Next, you can visually look at the electrode. If it looks dirty, then you can try cleaning it with an emery board, but if the electrode is already too thin, then you will need to replace that plug.

Also, it is a good idea to replace all the plugs if you are replacing one, so you know that they are all good. The electrode might not be dirty though, but the problem could still be the spark plug. If the gap on the plug is too big or too small than that can be an issue too.

You will need to look up the specifications for your mower and the gap it should be and then use a gapping measure to measure the gap. If it is off, then you need to replace the plugs.

4/ The cutting system

The last area that can cause your mower to stall while mowing is in the cutting system. What we mean is if you are cutting thick or tall grass, then it might be bogging down the blades and causing the engine to stall.

If you can tell that the mower is having trouble cutting on the level you have it set too, then you will need to raise the deck. If raising the deck doesn’t help, or the grass isn’t that tall or thick, then the problem might be in the blades themselves or under the deck.

If the blades are dull, then they will not cut well, and that can lead to the mower stopping. You will need to get under the deck and remove the blades to sharpen them. Once they are sharp, that should solve the problem.

If your blades are sharp though, then they might be getting bogged down for another reason. That other reason is you could have a lot of grass built up under the deck. If that is the case, you will need to get under it and clean it out.

If you are sharpening the blades or cleaning the deck, then you should go ahead and do both things since you are already under there. It doesn’t take that long to remove the blades to sharpen them if you are already cleaning under the deck and it doesn’t take that long to clean under the deck if you are already sharpening the blades.

By doing both, it will save you time later and make sure you get the best cut possible.

One thing to check is lawn mower battery, if it is weak, the best battery tender is the excellent tool to recharge your battery.


So, after reading this, you now know all the possible reason why your mower won’t stay running and also the solutions for them. The issue could be in air flow or fuel flow. In either case, you will need to clean those systems out.

It can also be due to bad ignition. If that is the case, you will need new spark plugs. Lastly, it might just be that the blades are dull, under the deck is dirty, or the grass is too thick and not be a mechanical issue at all. If it is from that, then you will need to sharpen the blades and clean under the deck or raise the deck.

Luckily most of the reasons why your mower is stalling are easy fixes if you know what to check, and now that you have read this you do, so you are well on your way to fix your mower that is dying and not has to worry about the engine stopping in the middle of cutting again.

How To Test A Voltage Regulator On A Lawn Mower?

Lawn mowers have a lot of parts and in the big picture work very similarly to cars. One of those parts is the voltage regulator. This part is similar to the alternator in a vehicle. The voltage regulator helps make sure the proper amount of charge is going back into the battery while the mower is running.

In this article, we will cover how to test a voltage regulator on a lawn mower to ensure that it is working properly. We will explain the steps involved and also when you might need to test it.

When to test?

Before getting into how to test the voltage regulator, we will briefly explain when you might need to test it. The main reason you would need to test the voltage regulator is if your battery kept dying and you already had the battery tested to make sure it was good.

If you keep ending up with a dead battery but know that it is a good battery, then it is time to test the voltage regulator.

How to test?

There are a couple of ways to test the voltage regulator, and we will explain both of them. Both ways are similar and do the same thing, so depending on your lawn mowers layout one might be easier to do than the other.

Thru the Battery

The first way to test the voltage regulator is thru the battery. The only tool you will need is a multimeter or voltmeter. Then follow the simple steps below.

  1. Locate and attach the positive read cable from the voltmeter to the positive terminal on the battery and then connect the negative or black cable to the negative terminal on the battery
  2. Put a light load on the battery. You can do this by partially turning the key, so the headlights are on.
  3. Next turn the voltmeter or multimeter on and make sure it is set to volts. It should be giving you a reading of around 12 volts.
  4. If it is giving you this reading, then that means the battery is good, and now you can start the mower and advance the tortilla to fast while keeping everything connected.
  5. Now check the reading on the voltmeter. It should be reading out higher. The reading should be at least 13 volts.

If the reading did not change, then that means that the voltage regulator isn’t working and needs to be replaced or repaired.

Thru the Voltage Regulator itself

You can also test the battery thru the voltage regulator itself if you can get to it. You can do that also with just a voltmeter or multimeter and by following the following steps.

  1. Locate the voltage regulator and attach the positive red cable to the positive terminal on the regulator. Then take the black negative lead and attach it to the negative.
  2. Next turn on the voltmeter or multimeter and make sure you have it set to the proper volts for your mower.
  3. Next turn on the lights of the mower by turning the key parts. This should give you a reading. If it doesn’t then that means the generator isn’t working.
  4. Next, start the mower and see that it gives a reading. The reading it gives should stay constant. If it is providing a reading, then that means the voltage regulator is generating power. If it doesn’t, it means it is bad.
  5. With it still running you can press on the generator brushes and see if that can get a reading. If it does it means the brushes are worn out and need to be replaced. If it still doesn’t, then you need a whole new generator.

What to do if your lawn mower battery is weak? Try to recharge it with the best battery maintainer, it will keep your lawn mower battery fully.


These are the two main methods for testing your voltage generator on your mower. Both methods are easy to do and can be done fast with just one tool.

All you need is a multimeter or voltmeter and to make sure you follow the steps provided. The key is to make sure you connect the meter right. Make sure the positive is connected to positive and negative to negative. Then start the mower and see if the voltage jumps or you get a reading.

After reading this, you can easily test your mower voltage generator and see if it is working like it is supposed too or if it is the cause of your repetitive dead mower batteries.


When To Turn Overdrive Off?

Cars these days have all kinds of different features. Sometimes you might not even know what the feature is or what it does, but the vehicle still has it. One of those features is overdrive.

A lot of cars have overdrive, and you just leave it on because that is what is commonly told to do. You may not even actually know what overdrive is or what it is used for.

Well, after reading this article you will know what overdrive is, what it does, and when to turn it off. Keep reading to have all your questions about overdrive answered.

When To Turn Overdrive Off

When to turn overdrive off?

What is Overdrive?

Before getting into it or when you should turn overdrive off, you first need to understand what overdrive is. Overdrive is a feature on your car that controls your transmission and in the process also controls your engine.

When you have overdrive on it allows the car’s transmission to shift into the top gear whatever that might be for the particular vehicle. While in the top gear this allows the car to drive faster with less strain on the engine.

That is because the top gear is a smaller gear that spins faster than the engine reducing the engine RPM (rotations per minute) to provide the same power to the wheels. This means the car can go faster easier.

What Do You Gain?

So, now we can look at what you gain when you have overdrive on. The main thing you gain is more power at lower engine RPMs at top speeds. This means that the engine is running more efficient and with less wear.

That means a longer life for your vehicle. This gain is hard to measure though due to other factors that go into engine life. One thing you gain though that can be measured is better gas mileage.

This is because the engine needs less gas when going at lower RPMs. The better fuel efficiency at tops speeds is why most people say to leave overdrive on.

Another benefit of overdrive is that it helps with breaking. That is because the car can shift out of the top gear when you slow down which will help you slow down.

This means that the engine will break the car along with the brake pads helping you to stop quicker. This breaking benefit means that does overdrive help reduce strain on the engine, but it also helps reduce strain on your breaks, which is a good thing because it helps your brake pads last longer and saves you money.

What Do You Lose?

So, the next question is what do you lose with overdrive on. Well, the main thing you lose is towing power. That is because with less strain on the engine it loses the ability to apply force to something.

The lower RPMs means that the engine is putting out less pulling power. Also, having the overdrive on can lead to the car switching between the top two gears depending on the situation. A lot of times this happens on hills or when traveling at speeds right between the top two gears.

When To Turn Overdrive Off?

So, when should you turn overdrive off. Well, the main time you will want overdrive off is if you find that you are having trouble pulling a load.

You can tell if you are having trouble because the RPMs will get high and the engine will audible have a strain on it. If that is the, you should turn overdrive off, so that the engine can have more power.

The other time to turn overdrive off is if you can tell the transmission keeps switching between the top two gears. It is easy to tell this because the engine will rev up and have the RPMs jump when the transmission downshifts, and then the RPMs will drop when the engine shifts back into the top gear.

If the vehicle keeps doing this repeatable, then it is bad on the car, and you will want to make sure it stops this. This normally occurs when going up and down big hills, especially if your speed keeps changing.

Is It Better To Have Overdrive On Or Off?

Is it better to have overdrive on or off? If you know the basic purpose of what overdrive is, another question is to determine whether or not if it’s safe for the vehicle. The answer to that is it depends. It depends on if you’re using overdrive for the right reasons. Improper use of overdrive will do damage to your vehicle. In this quick article, we’ll answer the question to determine whether or not if it’s a better idea to leave overdrive on or not.

First, what is overdrive? Overdrive is basically the highest gear in your transmission. The purpose of it is to allow the engine to operate at a low RPM. This is designed to make the vehicle more fuel efficient. Additionally, overdrive is also designed for quieter driving. Overdrive also prevents the transmission from repeatedly upshifting and downshifting. That’s because when a vehicle is towing a load, both the engine and transmission are most likely to shift.

So, when is it safe to have overdrive on? Alternatively, when is it better to have it off? The only time you can turn off overdrive is when your vehicle is towing a trailer, another vehicle, or anything else that would need towing. Another situation is when you are passing through other traffic or preparing to change lanes.

A good time when you can switch your transmission into overdrive is when your on the highway or in long and steady driving conditions. Alternatively, if you are dealing with road conditions where are considered hazardous due to rain or winter precipitation like sleet or ice.

In other words, while there is no definite answer to whether or not if it’s better to have your car’s overdrive on or off, there are instances when you’ll need to use it. Likewise, there will be times when you won’t need it.

Overdrive is a good thing to have in your vehicle. But you should always use it properly in the situation where it is warranted. Improper use will cause damage to your transmission or other parts of your vehicle. It’s not a matter of whether it should be on or off at all times. It is a matter of knowing when to use it.

Overdrive today

Today cars are pretty good at determining your speed and if they should be in top gear or not. That means that a lot of times you won’t need to turn overdrive off with the button and instead trust the car with if it wants to use the top gear or not.

Leaving the overdrive on will help make sure that the car uses it when it is going at top speeds where it is beneficial and then not using it when it is not beneficial.

This way you get the gas mileage benefit, engine strain benefits, and all the other benefits that overdrive overs and by leaving it on you won’t have to worry about turning it back on.

The only thing that modern vehicles lack is knowing if you are pulling a load or driving a lot of hills. If you are pulling a heavy load, then you might want to turn overdrive off yourself with the button.

That will save the vehicle from getting confused. Also, if you live in an area with a lot of big hills, or are going to be driving on large hills, then you might want to turn overdrive off on your own to save strain your transmission.

you might want to turn overdrive off

If you are pulling a load or driving a lot of hills, you might want to turn overdrive off.


Overdrive is just one of many features that most cars have today. Sometimes the vehicle may have overdrive, and you don’t even realize it. That is because most of the time cars are good at using overdrive when it is beneficial and only shifting into the top gear at top speeds when it is needed.

Overdrive provides a lot of benefits. The easily measured one is better fuel efficiency, but it also makes breaking easier and reduces strain on your engine.

That is why you should only turn overdrive off if you are pulling a big load or if your driving conditions are causing the transmission to repeatable shift between the top two gears.

If the transmission is constantly shifting or the engine is straining to pull a load, then you can turn overdrive off for that trip. Otherwise, it is wise to just leave overdrive on and not to turn overdrive off.

What To Do If Clutch Won’t Disengage?

In a manual or otherwise known as standard transmission car, there is the clutch. The clutch is connected to the extra pedal that is normally on the far left side.

Sometimes the clutch doesn’t always function properly. In this article today we will explain what the clutch does and also one of the problems that can come about which is it getting stuck or not disengaging.

Your clutch can not disengage for a few reasons which we will explain here, and we will also discuss the solutions to these problems. Read on to find out why your clutch gets stuck and what to do about it.

Clutch Won’t Disengage

How to troubleshoot clutch that won’t disengage

More: When the car is not used much, the battery can begin to lose charge because its not charged by the alternator. This is a common occurrence of classic cars that are only used on weekends . To keep the battery fully charged, you need the best battery tender for your car.

What Is The Clutch?

First, before getting into why the clutch might not disengage, we will cover what the clutch is. It will help to understand briefly what the clutch does before we get into why it might not work.

The clutch is what connects the engine to the transmission. When the car is running and moving the clutch is engaged. The clutch is a pressure plate that is hooked to the flywheel that puts pressure on the drive plate.

When you step on the clutch pedal, it moves this plate out of the way for a moment so you can shift gears. When you shift gears, it literally moves the old gear out of place and a different into place. The clutch then reengages when you lift off the pedal, and the plate connects with the new gear.

What Happens When It isn’t Disengaged All The Way?

So, now that you have the basic understanding then it will probably make sense to you that when the clutch isn’t disengaged all the way, then part of the plate is rubbing against the gears when you are trying to change gears.

Also, if the clutch is only partly engaged, then it will cause rubbing and friction. This causes the friction material to burn up and get wasted. It will also cause heat which will lead to wear and tear.

Eventually, the different bearings will wear out due to pressure and twisting forces and the system will break completely. This is bad, that is why if your clutch is slipping or not disengaging all the way you need to get it fixed as soon as you notice the problem.

What Can Cause It Not To Disengage?

So, now you are probably asking yourself what can cause the clutch to slip or not disengage. Well, there are four main things that can cause your clutch to slip. They are

  • Stretched or Broken Clutch Cable
  • Hydraulic Leak in Clutch System
  • The linkage is Out of Adjustment
  • Incompatible Aftermarket Parts

These are the common reasons, and we will look at each one in more detail if you keep reading.

1/ Stretched or Broken Clutch Cable

The most common reason for issues with your clutch is a stretched or broken clutch cable. The clutch cable is what connects the pedal to the clutch and tells the car to pull the clutch out of the way when you step on the clutch pedal. Luckily it is easy to check the clutch cable and replace it if it needs to be replaced.

For checking the clutch cable, all you need is a jack, flashlight, and some things to block the wheels off. A jack stand and googles also help for safety but aren’t needed.

The key when checking the clutch cable has put the car in park or first gear and engage the parking brake. Block the rear tires off and jack the front end of the car up.

Find the cable that is leading from the clutch and to the clutch pedal. Use the flashlight and visual look at it. See if it is tight or if it has slack. Also, make sure it isn’t coming apart or broke.

If it is loose or visible broken, then you need to replace it. All you do is unhook it from the clutch and the pedal and put the new one in. If the cable isn’t the problem, you can move to the next possible issue.

2/ Hydraulic Leak in Clutch System

The next most common thing is a hydraulic leak in the clutch system. Luckily this one is pretty easy to check, especially if you are already down under the car.

To check look for any liquids under the car especially around the clutch. Also, pay special attention to the slave cylinder and make sure it isn’t leaking.

Check the rubber boots to make sure the seal hasn’t failed and checked the hydraulic lines. After checking under the car, you can lower it and check under the hood.

Look at the master cylinder and see if there are any leaks. Also, check all the seals and lines from above as well. If you find any leaks, then the damaged parts will have to be replaced. You want to make sure there is no hydraulic fluid or oil coming from anywhere.

Depending on the part of the hydraulic system that is damaged and your experience you might be able to replace it yourself, or you might have to get a shop to do it.

The good thing is about checking it yourself though is you save the labor cost on that and can tell the repair shop exactly what is wrong with it so your vehicle can get repaired faster and cheaper. If the hydraulic system appears fine though, then you will have to start looking at the clutch alignment.

3/ The Linkage is Out of Adjustment

The clutch alignment or linkage may not be right, and this can cause it to slip or not disengage all the way. This issue can be a little harder to check, but you want to look under the car again for this.

You will jack it up the same way as already described. To see if the alignment is right you will want to look at the pin and cotter pin on the clutch linkage and clutch pedal.

If these are loose or in the wrong position, then they will need to be adjusted. You also want to make sure that the adjusting nut is tight. If it isn’t than tighten it down.

Outside of those couple things, it is hard to do anything to the adjustment yourself unless you are experienced. If you are experienced, you can try to make sure the plate is in the right position, but if you are not skilled with cars than you should just take your vehicle to a mechanic and let them look at the clutch.

If you think you have a clutch alignment issue and have checked the other things, then just let a shop take care of it because you can cause more harm than good working on it yourself if you don’t know what you are doing.

4/ Incompatible Aftermarket Parts

The last issue of incompatible parts is also another common problem. This is especially true if you tried to upgrade something on your own and don’t have a lot of experience.

Sometimes, especially if you buy something online, it will say it is compatible, but really it isn’t. If you have recently redone your clutch system and then start having issues, then there is a good chance the part you used wasn’t the right size.

To fix this, you can take it to a mechanic and let them use the right parts or try to find a different part that is compatible. When upgrading or working on your clutch save all the material when installing something new in case it doesn’t work, and you need to return it and also try your best to get matching parts or buy somewhere that guarantees the compatibility of the new parts.


A clutch that won’t disengage is a major issue. It causes the clutch to wear out faster and can also lead to unsafe driving conditions. That is why if you have a clutch that is slipping or not disengaging it is important to check it out right away.

Now you know the four common causes of a clutch that won’t disengage, and that is a stretched or broken clutch cable, a hydraulic leak in the clutch system, an out of alignment linkage or incompatible aftermarket parts.

Most of these issues are easy to solve and now know how to diagnose each of them and know what to do about them to fix them. After reading this, you are well on your way to get your stuck clutch fixed and car driving safely again.

Why Car Smells Like Burning Plastic?

Your car can produce a variety of smells while running. The smells that your car makes aren’t always good either. Some of the smells that can be produced are burning smells, and one of those burning smells is burning plastic.

You may be having this smell from your car and be wondering what is causing it. Well, read on to find out the different causes of a plastic burning smell from your car and also how to solve them.

Why Car Smells Like Burning Plastic

Why Car Smells Like Burning Plastic?

When does it happen?

Determining when the burning smell occurs is one effective method to determine why it is occurring. For instants, some burning smells happen when you first start the car, while other burning smells occur when you turn on certain components of your car or do certain things.

It is important to pay attention to when the burning smell starts because that can help you figure out why it is happening. With burning plastic smells a lot of times it will occur when you turn on your car’s heater or other electrical devices.

Smell from Heater

the smell is coming from the heater

The smell is coming from the heater

If the bad smell starts when you turn on the heater, then there is a good chance that the smell is coming from the heater. If you haven’t used the heater in a while, then the smell might just be dirt and dust burning off.

If that is the case, then it will go away after a little use. Once the dust and dirt have burned off, then the bad smell will stop. If the bad smell doesn’t stop though or if it occurs even when you have already been using your heater, then it is coming from something else.

One of the common other things with the heater that could be causing the smell is you might have gotten some plastic debris, such as a bag stuck in the heater system.

You should check under the hood, in the engine area, and up under your car to make sure that no plastic bags are stuck anywhere. A bag that is stuck could be melting as you drive.

There are a lot of plastic bags on the road, and it is easier than you might think to get one stuck up under your car. Outside of the burning smell that is annoying, it is important to get the bags removed as soon as possible because it can damage other parts of your car.

A plastic bag can get stuck in a fan or cause something to overheat, so if you smell burning plastic, then it is a good idea to check for bags.

Lastly, burning smells from the heater could be coming from a broken heater or another component near the heater. If you check for a plastic bag and don’t find it, but have a burning smell, then you need to take the car to a shop and have a thru inspection done. When come to shop, you should ask the shop using best battery tender for car storage to recharge your battery if it need.

For instance, you might have antifreeze leaking and it burning off smells like plastic. Also, a heater component could be melting, and this could smell like plastic too.

If you have a burning smell coming from the heater and you have clean it, then it is a good idea to have it checked out to make sure nothing serious is wrong.

Electrical Short

 it is probably an electrical short

It is probably an electrical short

If you have a burning plastic smell when you turn on something else besides the heater, then it is probably an electrical short. This happens when the plastic coating on wires, fuses, or other connections wear off or burn off.

The issue is with whatever system you turned on when the burning smell starts. For instance, if you start to use your power windows and the smell starts, then it is the window system that has the short.

The reason why these occur is that the electrical wires get hot when you use the components. This heat is hot enough to melt the wire coating sometimes, and this melting is the smell that you smell.

The wire coating is easier to melt as it gets older. This is especially true if the wire coating gets cracked or damaged. That is because the wires inside can be exposed to things that it is not supposed to and heat up easier or cause a spark.

The good thing is that if the burning smell is occurring from an electrical short, then all you have to do is replace those wires. The hardest part with electrical issues is tracking them down though.

That is why it is extremely important to pay attention to what you are doing when the bad smell starts. The better you are at paying attention to what system is causing the smell, the more money you will save on fixing it.

It can take a lot of time looking at the electrical system if you can’t give the mechanic an idea of what part of the car to start looking at to find the short.


Bad smells can come from your car for a variety of reasons, and there can be a variety of bad smells. After reading this though, you now know what causes bad burning plastic smells and how to fix them.

You know that if you have a burning plastic smell, it is very important to pay attention to what you turned on in your car when the smell started because that will make fixing it either.

A lot of times it will be your heater or another electrical component. If it was something besides the heater than it is a short in a wire and you just have to replace the wires.

If it was the heater however then it could be a few things. If could be dirt burning off or a plastic bag that is stuck. If the heater has been running for a while though and you have checked it for a plastic bag, then it might mean a bigger component is broke.

You will need a mechanic to look at it to make sure it isn’t leaking antifreeze or that a vent or the motor isn’t melted. A mechanic will find the problem if it is one of those things and you can have it fixed. The key is to stay on top of things if you have a burning plastic smell and don’t ignore it or things could get worse.

Which Battery Cable To Connect First?

Their are a variety of reasons why you might remove your battery from your car, boat, mower, or other equipment with a battery. It could be to charge it or to replace it.

Well, no matter why you removed the battery it brings up a common question when you go to put the battery back in and that is why wire to connect first.

Their is a debate amongst people on if you should connect the positive wire or the negative wire first. Well, after reading this article you will have an answer and reasoning to this question.

Which battery cable to connect first

Which battery cable to connect first?

Which to connect first?

So, which terminal should be connected first when reinstalling a battery. Some people say it doesn’t matter because no circuit is being made when only one wire is connected.

While that is true that not circuit is being made thru the battery, it is still possible to complete the circuit. That is why the answer to which wire to connect first is the positive wire. By the way, if you are intending recharge your car battery, i think you should have the best battery tender to do it, it will keep your battery in good condition.

Why connect positive first?

The reason you connect the positive first is that the negative is the ground wire. You don’t want the ground wire to be connected first because then the circuit will be completed as you try to connect the positive which could lead to sparks.

These sparks could shock you or worse short out the battery or other components. That is why it is important to make sure that the positive is connected first.

With the positive connected, then when you go to connect the ground sparks will not occur because it will go into the ground wire. This will keep you safe as you connect the wires and also keep the components in your vehicle or equipment safe.

Other times

This same question also doesn’t always come about when reconnecting a battery, but instead when jumping a battery. When jumping a battery also want to make sure that you connect the positive clamp first and then the negative clamp.

This is for the same reasoning as when reconnecting the battery. It keeps sparks from happening and shorts from happening. This applies to the good battery as well as the dead battery.

Connect the positive clamp first and then the negative clamp

Connect the positive clamp first and then the negative clamp when jump a battery


When disconnecting the battery or jumper cables it is the opposite. You disconnect the negative first and then the positive.


Their are a variety of times when you need to connect a battery into your car or other piece of equipment such as a mower or boat. When you need to connect the battery it is important to connect the positive first and then the negative.

This keeps you safe as well as the equipment safe. You might have heard that it doesn’t matter, but after reading this you can not see that it does.

A circuit can be made when connecting the battery be it the wires touching something or the tools that you are using. If it is already grounded and the positive wire touches something than a spark will occur. This won’t happen if it is the other way around though.

Reconnecting your battery isn’t the only time that you will be connecting wires to your battery however. It is important when jumping a battery and connecting jumper cables to also remember to connect the positive terminal first.

This applies to the good battery and the dead one. It is a good habit to always connect the positive first and then the negative and when disconnecting to disconnect the negative first and then the positive.

After reading this you now know the answer to which battery cable to connect first.
