It was the middle of summer, and the heat was oppressive. The air conditioner wasn’t working, and I cursed myself for not getting the car serviced when I had the chance. In reality, it was all happening due to a worn-out serpentine belt that broke at last.
Now, with a broken serpentine belt, it was just a death trap waiting to happen. The engine started making a strange noise and began to overheat. That day I learned if your car starts making a loud noise, it’s probably time to replace the serpentine belt.
This article will discuss the symptoms of a bad serpentine belt and the causes and replacement costs. We will also answer some of the most frequently asked questions about serpentine belts.
What is a Serpentine Belt?
A serpentine belt, also known as a multi-rib belt, is a type of drive belt used to power multiple devices in an automotive engine. The belt is made up of several interconnected ribs that help it flex and conform to the various curves and angles in the engine bay. A serpentine belt can power everything from the engine’s cooling fan to the air conditioning compressor.
The serpentine belt was first introduced in the early 1990s as a replacement for the V-belt, which was prone to failure and required frequent replacement. The serpentine belt is now the most common type of drive belt in automotive applications. It is also more efficient than the V-belt and can last twice as long.
If your car has a serpentine belt, keeping it in good condition is important. A worn or damaged belt can cause several problems, including engine overheating and loss of power.
What Causes Serpentine Belt To Go Bad?
The serpentine belt is a critical part of the engine system in a car. When it goes bad, it can cause all sorts of problems. But what actually causes the belt to go bad in the first place?
A few things can cause a serpentine belt to go bad. One of the most common is age. As a belt gets older, it starts to wear down, and eventually, it may break. Another common cause is heat. If the belt gets too hot, it can start to wear out and break. Mechanical problems can also cause a belt to go bad, as can foreign objects that get caught in it.
If your serpentine belt is starting to show signs of wear, it’s important to replace it as soon as possible. A broken belt can cause a lot of damage to the engine, and it can be very expensive to repair. So if you’re not sure whether your belt is in good condition, have a mechanic look at it.
Symptoms of a Bad Serpentine Belt
A few symptoms can indicate a problem with the serpentine belt. The most common ones are:
- Failure To Start
- Squealing Noise From Engine Bay
- Cooling System Failure
- Flickering & Dimmed Headlights
- Worn Out Belt
- Power Loss
- Battery Light Warning
- Faulty Power Steering
- Poor Air Conditioning
- Fallen Serpentine Belt
Let us take a closer look at these symptoms:
1. Failure To Start
A bad serpentine belt can definitely cause starting problems in your car. If the belt is frayed or damaged, it can slip off of the pulleys or break completely, preventing the engine from turning over properly.
In some cases, a broken serpentine belt can also prevent the alternator from charging the battery, leading to starting problems. So if you’re having trouble starting your car, it’s definitely worth checking the condition of your serpentine belt.
2. Squealing Noise From Engine Bay
If you hear a squealing noise coming from the engine bay, it’s most likely a problem with the serpentine belt. The squealing noise is caused by the belt slipping on the pulleys. This can be caused by many things, including age, wear, and tear, or damage.
One of the most common reasons a serpentine belt may squeal is that it has become loose. As the belt begins to loosen, it will no longer have proper tension and contact with all of the pulleys. This can cause the belt to slip, which produces a squealing noise.
In addition, a damaged or worn serpentine belt may also squeal. If the belt is excessively worn, it may no longer be able to properly grip the pulleys, which can also cause squealing.
A defective tensioner may cause a serpentine belt to squeal in some cases. If the tensioner is not applying enough pressure to the belt, it can cause the belt to slip and squeal.
3. Cooling System Failure
If the serpentine belt is not working properly, it can cause the cooling system to fail. The serpentine belt is responsible for driving the water pump, which circulates coolant through the engine. If the belt is damaged or broken, the water pump will not be able to function properly, and the engine will overheat.
In addition, a damaged serpentine belt can also cause the radiator fan to fail. The radiator fan helps to cool the engine, and if it is not working properly, the engine will overheat.
If you notice that your car’s cooling system is not working properly, it’s important to check the condition of the serpentine belt.
4. Flickering & Dimmed Headlights
If the serpentine belt is damaged or broken, it can cause the headlights to flicker or dim. The reason for this is that the serpentine belt drives the alternator, and if the belt is not working properly, it can prevent the alternator from charging the battery.
As a result, the headlights may flicker or dim when the car is idling or at low speeds. If the problem is severe, the headlights may even go out completely.
If you notice that your headlights are flickering or dimming, it’s important to check the condition of your serpentine belt.
5. Worn Out Belt
If you can see that the serpentine belt is cracked, frayed, or otherwise damaged, it has likely gone bad and needs to be replaced.
A serpentine belt can become worn out over time due to age and wear and tear. As the belt begins to wear out, it will no longer have proper contact with all of the pulleys. This can cause the belt to slip, which can produce a squealing noise.
If you notice that your serpentine belt is beginning to show signs of wear and tear, it’s important to have it replaced.
6. Power Loss
If the serpentine belt is damaged or broken, it can cause a loss of power. A serpentine belt is responsible for driving several engine components, including the alternator, power steering pump, and water pump.
If the belt is worn or damaged, it can cause these components to work less efficiently, resulting in poor engine performance. A broken serpentine belt can cause the engine to overheat or stall in extreme cases.
If the belt is not functioning properly, it can cause the engine to work harder, leading to a decrease in power and efficiency.
7. Battery Light Warning
If the serpentine belt is not working properly, it can cause the battery light to come on. The serpentine belt drives the alternator, and if the belt is damaged or broken, it can prevent the alternator from charging the battery.
As a result, the battery light will come on to warn you that there may be a problem with the battery. If you notice that the battery light is on, it’s important to check the condition of your serpentine belt.
8. Faulty Power Steering
If the serpentine belt is not working properly, it can cause the power steering to fail. The serpentine belt drives the power steering pump, and if the belt is damaged or broken, it can prevent the pump from working properly.
A bad serpentine belt can cause several problems with power steering, including loss of power steering assist, increased steering effort, and unexpected changes in steering response.
These problems can make driving difficult and even dangerous. In some cases, a bad serpentine belt can also cause the power steering pump to fail.
9. Poor Air Conditioning
If the serpentine belt is not working properly, it can cause the air conditioning to fail. A car’s AC system has many potential causes of poor performance, and a bad serpentine belt is one possibility.
If the serpentine belt is not functioning properly, it can prevent the compressor from turning, which will, in turn, reduce the amount of cool air that is produced by the AC system. Other potential causes of poor AC performance include a low refrigerant level, a faulty compressor, or leaks in the system.
Any of these issues should be addressed by a qualified mechanic in order to ensure that your AC system is functioning properly.
10. Fallen Serpentine Belt
If your serpentine belt keeps falling off, it could be a sign that the belt is damaged or has stretched beyond its usable lifespan. In either case, you’ll need to replace the belt. If your vehicle has an automatic tensioner, you may also need to replace that component. Check your owner’s manual for specific information on your vehicle.
