What are the causes of a Car squeal? The article will give you the anwer to the question in details.


If your car is squealing,What are the causes of a Car squeal? Articles it must due to the car belt system. A serpentine belt system that most vehicles have is a single continuous belt that "snakes" around the pulleys of the multiple peripherals on the front of an engine. Systems such as the alternator, the power steering pump or water pump are all interconnected by this single belt. Vehicles may have multiple V-belts for each of the different systems requiring them while vehicles that manufactured prior to the late 1980's may not have a serpentine belt.

There are many reasons that a belt squeals for many reasons but the most common three are below:

There may be fluid on the belt. The belt may be too loose or the belt may be too tight.

In order to find out which of these is most likely causing the squealing you should first open your hood and find your belt. You can easily find it, as it looks like a big black rubber band snaking around the front of your engine. Now rub the belt with a rag, if the rag soaks up fluid than that is most likely the cause of the squealing. Fluid on your belt can be caused by one of two things; one is that something may have recently leaked on your belts. For example you may have spilt oil while adding to your reservoir. If that is the cause you should use a low pressure hose to wash your belt, ensuring that the runoff is properly cleaned and disposed of. Then wipe your belt dry with a clean rag. At last, allow the motor to idle for a few minutes to dry any water and then drive your car, if the squealing stops then that should be the end of the your problem.

That’s because your belt may be either too tight, or too loose if there is no fluid on your belts. One fast way to check if your car belt is too loose is pouring water over the squealing belt while the motor is running. If the squealing stops which means your belt needs tightening. You can look for the belt tensioner which looks like a wheel connected to an arm, about half-way down the front of the engine. The tensioner located obviously between car models therefore you may need to consult your car manual. The ideal tension on the belt is around 3/4 of an inch play evenly throughout, any less or more than this can cause squealing, and reduce the lifespan of our belt.

If these three options fail, an alternative may be belt dressing compound which should be obtainable at any automotive shop. To apply, while the engine is running, carefully hold the stick against the moving belt. One should bear in mind however that while this compound may silence the squealing, it is only a temporary solution, and will only quiet the symptom, not fix the problem.

If you have already followed the above tips but the problem still exists, you should check elsewhere in the vehicle, such as the power steering fluid reservoir, the water pump, the wheel bearings, or the brakes. If the problem still cannot be solved then I advise you to take the vehicle to an auto mechanic for further examination.
