The fan belt is a flexible belt made of rubber that drives various accessories in the engine bay. Commonly referred to as the serpentine belt due to its long, winding path around multiple pulleys, it powers components such as the alternator, air conditioning compressor, power steering pump, and, of course, the engine cooling fan. The function of the fan belt is to convert the rotary motion of the engine's crankshaft into useful work for these accessories, ensuring that they operate efficiently.
