What is a Serpentine Belt?
A serpentine belt is a long belt that winds around several pulleys in an engine. It is responsible for powering several components of the engine, including the alternator, power steering pump, and air conditioning compressor. It is a looped belt, which means it has no end, and it is kept tight by a tensioner. The belt is made of durable materials such as rubber and nylon, which can withstand the heat and pressure generated by the engine's operation.
