A serpentine belt is a long, continuous belt that is used to drive multiple peripherals in an engine, such as the alternator, power steering pump, water pump, and air conditioning compressor. The term serpentine refers to the belt’s winding path through various pulleys. A double-sided serpentine belt, as the name suggests, has grooves on both sides, allowing it to grip the pulleys more effectively. This design enables it to drive multiple accessories on either side of the belt.
