What Is A Drive Belt?

The drive belt, also known as a serpentine or accessory belt, is the main belt that is doing all the hard work and makes your engine run perfectly. If you have a front-wheel-drive car. You will notice the belt on the left side of the engine bay. If you are running on a rear-wheel-drive car. The drive belt should be right in front of you. Right in between the engine and the cooling radiator fan.

You can also easily identify these belts by their distinctive ridges that run through the length of the belt. These ridges are helping the belt to maintain its grip and stay in place.

This belt is running all the engine accessories. You will be surprised if I tell you that the air conditioner you are running in your car, runs with the help of the engine. The engine spins the driving belt. Then the belt spins the compressor and delivers cool air to your cabin.

It also runs other accessories. Such as the alternator. The alternator needs the serpentsine belt to spin, in order for it to produce power to the car. This energy then helps charge up the battery and you are able to crank your engine every morning.

For example, if you run a supercharger. The serpentine belt run the power to the supercharger. Based on the size of the pulley that is installed on the supercharger, it delivers the proper number of rotations.

If the pulley is big, it delivers less power. If the supercharger pulley is smaller. It will deliver more air to the supercharger and also more power from the engine output. But more about that later. And first, let’s learn the differences between a drive belt and a timing belt. And also we will find out more about the drive belt replacement cost.

Drive Belt Is Not A Timing Belt

Many people that are not experienced in cars, will easily confuse these two types of belts. But we will make this clear and describe what are the differences between the two.

The drive belt, as we said before, is meant to run the accessories. These accessories include the alternator, pulleys, superchargers, air conditioning compressors. These accessories need the turning motion of the engine in order to function.

The timing belt on the other hand is different. This belt ensures that the crankshaft and camshaft work in perfect harmony and the engine delivers power to the wheels. If this belt breaks it’s going to cause catastrophic engine damage. It will bend your valves because they are going to hit the pistons.

This happens because the timing of the engine is messed up. The crank and the camshaft are not synchronized anymore. Changing your belt on time will prevent this from happening, and you will probably never experience this issue.

If you are running a noninterference engine. An engine in which the camshaft is not overhead, but it is in the block. An example of this type of engine are the old pushrod V8 engines. In these engines, the camshaft is in the center of the block. So, if the chain or belt snaps, it wouldn’t damage the engine.

In the modern V8, inline 4 or inline 6. The camshafts are located on the top of the engine. In case of the belt snapping, it is going to ruin your engine in an instant.

Engines that use timing chains do not face this issue. Because the chains are made to last forever. And even if they lose the tension. It may just cause an unpleasant sound. This sound is a sign that your chain is time to be retired and replaced. Timing chains usually last around 150k miles.

What If My Belt Squeak?

Driving belts may squeak if there is some loose tension on them. This may be caused by an old driving belt that needs replacing. But it can be also caused by pulleys that need to be replaced or tightened up.

The main reason for this issue is the crankshaft pulley. This pulley, especially if you are running an LS engine. Knows to go bad and needs a replacement. If it’s bad you can notice that it is wobbling around and has a lot of play.

When you address this issue. It is also a smart idea to go through all of the other accessories. Namely, the water pump, air-conditioning pulley, drive belt tensioner pulley. Change all of these when you are doing your driving belt. It is a smart idea to do this job, because you may need to make another trip to the mechanic’s shop. And search online for drive belt replacement cost. So, if you don’t want to do the same thing twice. Do everything that needs doing at once.

Replacing all of these things at once will save you a lot of cash in the long run. Especially, if you want to keep the car, or sell it for a profit. People will instantly see these issues and go away. So, don’t wait and fix these issues with the squeaking belt.

What Is Going To Happen If The Driving Belt Snaps?

If the belt snaps, it means that your car will not be drivable. You will need to go to a mechanic’s shop for the belt to be replaced. Since the driving belt is powering many accessories, you may lose the power steering capability. As the belt breaks, there will be no power to the power steering pump.

Another issue that may appear. The battery is going to stop charging since your belt wouldn’t power the alternator anymore. The alternator needs something to spin it around. In order to make power for all of your auxiliaries, radio, lighting, etc. If the alternator doesn’t work. Your battery will go empty and then everything will shut down.

Another issue is the water pump. The pump is pumping water throughout the block to deliver proper cooling for the engine. If the water pump doesn’t move, the engine will overheat and it may warp your head or crack the block. This can ruin your engine and you will need to get a new one. You probably don’t want to go on that route.

These problems may skyrocket your spending on driving belt replacement costs. In the end, you may pay ten times more than you would originally have to. In my opinion, when you see that the belt starts to crack, you should not delay the change. Everything that’s delayed will be more costly in the end.

Symptoms Of A Broken Drive Belt

There are many symptoms that will appear when the timing belt is bad. You should not just ignore these symptoms and wait to get fixed on their own.

No Power Steering

One of the first symptoms that appear when the drive belt is bad is loss of power steering. If the belt snaps you will instantly notice that your wheel isn’t turning easily. The steering wheel will need a lot of force to be applied on it, in order to turn.

Another reason why you may lose power steering is the power steering pump. These pumps are notorious to go bad on some cars. They need to be changed, in order for you to get proper power steering.

No Air Conditioning

If your belt snaps, you will lose your air conditioning. Because one of the accessories that run on the drive belt is the air condition compressor. These compressors are also notorious for going bad and need to be replaced. Because of this you should not jump to conclusions and think the belt has snapped.

Also, there is some of the air condition piping that may have a hole. The freon that is inside the pipes may just escape and you will be left with no freon. This means that your air condition will not engage when you press the button. So, it is important to stop on the side of the road and check if everything is ok with the belts.

Squealing Sounds

Another symptom of a bad drive belt is the squealing sound that the belt is making. If the belt squeals when you apply the gas, it means that there is low tension on it. This may be caused by cracking or a loose pulley. Or maybe both. If the tensioner is loose. The simple solution will be to torque the tensioner more and that will increase the pressure. Stopping the squealing noise in the process.

Another thing that causes this, is bad pulleys. If they have a lot of play in them, then they are probably bad and need replacement.

Dead Battery

Another reason for a broken drive belt is a dead battery. If your battery dies off all of a sudden this may be one of the culprits. But you shouldn’t jump too quickly to conclusions. The alternator that is powering the battery is also notorious for going bad.

Inspect under the hood and if you see that the belt is ok, but the battery is always empty, maybe it’s the alternator. Alternators come cheap and they are easy to replace, with just a few bolts.

Also, the reason for a dead battery may be, just a dead battery. Batteries these days last for around 3-5 years. Then they need a proper replacement with a new one.

Overheating engine

If your engine overheats all of a sudden. This may mean that the belt has snapped. Because the water pump will lose power and the water will stop moving around the engine.

When you notice that the engine overheats. It’s important to stop your vehicle. Look under the hood and wait for it to cool off. Check the belts. If the belt isn’t snapped, it means that maybe your water pump or thermostat went bad and needs to be changed.

Symptom Summary

All of these accessories that are mounted on the belt are prone to failures. Water pumps, alternators, air conditioning compressors, pulleys and power steering pumps. Don’t jump to conclusion that the belt has snapped. If the belt has snapped you will see failure on all of these parts at once. Because there isn’t any power to them to keeps them running.

In this case, you may conclude the belt went bad. Also, take your phone camera and inspect the belts and their overall health. You are going to spot a worn-out or snapped belt in an instance.
