What is a Serpentine Belt?
A serpentine belt is a long, continuous belt that wraps around multiple pulleys in the engine of your car. The design of the serpentine belt allows it to transfer power from the engine to various accessories in your car such as the air conditioning compressor, alternator, and power steering pump. As the engine runs, the serpentine belt rotates along with the crankshaft pulley to operate the accessories that rely on it.

Without a properly functioning serpentine belt, many of the accessories in your car will not be able to operate properly. For example, the air conditioning compressor won't be able to cool the air in your car, the alternator will not be able to recharge your car's battery, and the power steering pump won't be able to help you steer your car easily.
