How To Fix A Broken Serpentine Belt


A serpentine belt goes around a pulley in your engine, either directly or via another belt. If you have ever noticed that your car is taking longer and longer to start, it may be due to a broken serpentine belt!

Serpentine belts typically contain steel plates or strands that are connected together. These connections lock into place when the belt is put onto a dry-clutch pulley (also called a sheave). When the engine is started, the clutch engages, spinning the pulley and putting tension on the serpentine belt.

The plastic portion of the belt can break away from this friction, leaving parts of the belt disconnected. This kind of break happens because of excessive heat as the engine turns, or physical stress caused by repeated use.

If you notice any sounds like metallic rubbing or clanking coming from your engine, check out the serpentine belt! It could mean something is wrong and you need to get it fixed quickly.

Fortunately, there are some easy ways to fix a nonfunctional serpentine belt. You will also need a tool that has an open end, such as a screwdriver or thin metal comb.

Check the tension of the belt

A serpentine belt goes through your engine several times, which helps it to work properly. As such, there is some elasticity to it so that when it gets stretched out, it will slowly return to its normal size.

However, if the belt is too tight, then it can cause issues by cutting off airflow or preventing the engine from starting. If you notice that your car takes longer than usual to start after cleaning or changing the oil, this could be the culprit!

To check whether this is the case, remove the cover from the serpentine belt (this requires taking off the plastic covers located under the hood). Then, pull up one side of the belt to see how much slack exists within it. If it’s very little, it may need to be replaced.

But before you do that, make sure to check the tension of the belt first! You can use a tool designed just for this purpose. Simply place the tool onto the end of the belt where it meets the pulley and push down firmly.

Replace the belt

A serpentine belt is an engine component that gets thinner as it loops around your car’s pulleys. Because this part of the engine doesn’t get thicker, it can cause issues in how fast the engine spins up when you start the vehicle.

If you are noticing excessive noise or feel uncomfortable pressure while driving, it is important to have a good understanding about serpentine belts. Luckily, there are some warning signs that indicate if this part needs replacement.

It is best to be familiar with serpentine belts before experiencing damage or failure. If you are ever unsure whether this part needs replacing, do not hesitate to visit your local auto shop for help!

Hopefully you will never need to work on a broken serpentine belt, but if you ever do, you will know what to do. Now, let us talk about how to fix a broken serpentine belt.

Tighten the pulleys

One of the first things you should do if your serpentine belt is breaking down is check to see that the front and back plates in the engine’s V-belt system are tight! If they are not, then it can cause the chain to slip and break due to excessive pressure.

The front plate goes along side the crankshaft pulley and the rear one goes next to the camshaft pulley. Make sure both of these parts have enough space to move freely without getting stuck or vibrating too much. This could also cause damage to either part since they are meant to hold tension and keep everything working smoothly.

If both of these parts seem very loose, try grabbing some heavy test equipment (like a weight scale) and tightening them up until they feel solid. Then reattach the serpentine belt and make sure it works properly before loosening off the screws again.

Check the serpentine belt for damage

If you are experiencing grinding or clanking sounds coming from your engine, it could be due to a broken serpentine belt. A serpentine belt connects all of the transmission components (such as gears) together.

A broken serpentine belt can cause problems with power delivery and efficiency in your vehicle. It may also lead to mechanical failure if not replaced soon!

If you hear any unusual noises while driving, have a look under the hood to see if there is anything abnormal. You might need to test the belts yourself to determine whether they are bad.

You can do this by simply changing the position of each belt. For example, take off the coverings that keep the engine warm and check the front timing chain belt. Or remove the plastic covers over the back wheels and check the rear wheel bearing cap.

Once you have determined which one of the three belts is the culprit, you will need to get them repaired or changed.

Get engine repair service

A serpentine belt is an integral piece of equipment in your car that helps transfer power from the crankshaft to the camshaft or other parts such as the valves, lifters, or fuel injectors.

A serpentine belt works by pulling off pieces of work at different angles and pulleys. When it comes together, it re-attaches parallel to the shaft it was attached to before breaking. This way, it can transmit torque without having to turn around or loop back on itself!

If you are looking to do some basic maintenance on your vehicle, then this article will show you how to fix a broken serpentine belt. You will also learn about when to get your car serviced for one versus the other so that you know which ones are expensive due to the length of time it takes to complete them.

The first thing you should do when trying to fix a broken serpentine belt is check it for any signs of breakage or wear. If you can get into the vehicle with the engine running, then great! But if not, you can use your hand to test it.

If you feel vibrations while doing so, then the belt may have broke already. You will want to make sure that you don’t remove the entire belt though as this could cause greater harm.

Only take off enough of the belt to expose just the pulley wheel at each position. This way you can tell whether or not there is still some friction in place before replacing it.

Once you have checked both positions, try reassembling the belt and see what happens. It could be bad luck, but sometimes these belts just give up.

Change the belt

A serpentine engine belt is an integral part of your car’s automatic transmission system. It moves aside as the engine turns, then tightens down as it spins faster. Your vehicle may tell you that your serpentine belt is broken, but it isn’t!

A serpentine belt can break due to friction or deterioration caused by heat. If yours looks like it has lost its elasticity and is no longer moving easily with each turn of the engine, it might be time for a change.

The most common cause of a broken serpentine belt is excessive heat. As your car heats up during normal use, the hydraulics in the transmission will warm up as well. This creates extra stress on the serpentine belt, causing it to snap.

It is important to note though that even if your serpentine belt does not look worn out, it could still be damaged. In this case, replacing it would not help unless the damage was repaired properly.

Luckily, professional auto repair shops are trained in changing these belts. They have tools and equipment designed just for this task.

The first thing you should do if your engine is performing slightly worse than it was before is check your serpentine belt. A new or worn out belt can cause issues, so make sure yours isn’t damaged.

If you are ever in need of a replacement belt, You will want to get one that has leather lining. This helps keep heat away from the pulleys which help prevent overheating of the system.

You also want to be careful not to pull too hard on the belt as this could break it. If needed, use a tool to aid in pulling it off correctly.
