What is a serpentine belt?
A car’s serpentine belt helps power many of the vehicle’s accessories, including the water pump, the alternator, and the power steering pump, to name a few. Older cars may have a serpentine belt that requires manual tightening to keep things running smoothly, but most modern cars have automatic belt tensioners. Serpentine belts may fail sooner than normal if exposed to engine oil or coolant leaks.
