Importance of using a serpentine belt

Serpentine belt provides mechanical power for other components

A serpentine belt plays a significant role in powering various components. One of these components is the steering system which depends majorly on power delivered by the belt. The serpentine belt also powers the radiator fan, water pump, and air conditioner compressor.

Serpentine belt provides basic function to the car

A car cannot function without a serpentine belt. This is why when it wears off; the performance of your vehicle will be lowered making these components not to work properly.

Helps supply power to the electrical charging system

The serpentine belt provides power to the charging system by attaching itself to the pulley alternator which supplies electricity to the car battery. This helps build and hold enough electrical power on your car battery.

Helps regulate your car moving speed

Modern serpentine belts have a tensioner which helps control the rate at which the belt runs. When the belt wears off, you will receive signals before things get out of hand. This is why you will experience a slow movement of your vehicle when the belt wears off.

Regular examination of your belt can help identify problems early enough.

Things to consider when buying the best serpentine belt

Not every serpentine belt will work with your car model. Before making your purchase, it is a good idea to check if your belt has met all the following requirements.


Serpentine belt size is an important feature to be on the lookout each time you are buying your belt. Your old belt can help you determine the size of the belt that will perfectly fit your car.  Your manufacturer’s manual should help you achieve this much faster.

Measuring your belt can also be another way of determining its size.


Serpentine belts are designed to last. A quality Poly-V belt should have passed the test of time and should meet all the industry standards. Belts with rib and pulley wear resistance last longer and are recommended.


Belt compatibility is a critical aspect to check out before paying for your Poly-V belt. Compatibility of your serpentine belt should be determined by how the belt works with other components like the pulley, engine, tensioner and other accessories.


To be on the safe side, always consider buying poly- v belts with extended warranty period should the unexpected happen.

Common serpentine belt problems and how to fix them

Chirping sound

Pulley misalignment may cause your car to produce a chirping sound. This happens when the serpentine belt ridges come into contact with the groove sides sliding downwards. To fix the problem, try to remove the belt and return it.

Another cause of chirping sound is a cracked belt. Inspect if your serpentine belt may be having cracks. Alternatively, you can use a WD40 and spray it on the belt while the engine is running. In case the sound goes away, it is time to replace your belt.

For cars which use serpentine belt tensioner, a chirping sound may be an indication of a faulty bearing or wheel. Remove the belt and try to spin out the tensioner by hand. If the sound does not go away, then your tensioner requires replacement.

Squeaking noises

Squeaking noises are an indication of an old serpentine belt. In case you experience this sound inspect your belt for any signs of wear. If your belt is new, the sound can be fixed by spraying water while your engine is still running.

Another cause of squeaking noises is pulley misalignment. If these sound increases after spraying water this could be a pulley misalignment.

Swollen, flaky or sticky belt

When oil leaks, it causes your serpentine belt to be flaky. When the oil spread on your belt, it weakens the rubber bonds making the belt spongy and soft. To diagnose the problem, replace your belt and avoid using belt sprays.

What makes a good serpentine belt?

  • A good serpentine belt should be easy to install and maintain
  • A great serpentine belt should work with other components in harmony
  • An excellent serpentine belt should perform its function
  • An excellent serpentine belt should withstand the test of time an meet the industry standards


Serpentine belts are designed to last longer, but with time they will require replacements. Often at times, we tend to ignore them. Using a worn out or faulty belt can make driving your car next to impossible.

However, serpentine belts vary in size, design, material, and performance which require one to be vigilant when purchasing. While the above features are important to look at, the best serpentine belt you choose by the end of the day should be compatible, of high quality, of the right size and above all performs its function perfectly well.
