Have you ever gotten into your car and as soon as you start the engine you notice a high-pitched squeal then when you accelerate or make a turn it gets louder? What is the cause of this?
The most common cause of a squealing engine is a bad or failing serpentine belt – also known as the drive belt. The belt is under your hood and wraps around multiple pulleys. It connects the crankshaft to other systems including the alternator, power steering pump, AC, and water pump. When the serpentine belt stops working so do these systems. In this article, we will outline reasons your serpentine belt may be squealing and how to tell if your serpentine belt needs replacing.
