Acts as a transmission belt, a V belt is a single continuous belt that drives the alternator, AC compressor, power steering pump, water pump, and other peripheral devices in a car engine. A belt tensioner or an idler pulley may guide the V belt. These belts are trapezoidal in shape.

Though these belts have a good lifespan, we should inspect them after every three years or 60,000 kilometers of use. Replacing these bets every three to five years can reduce the risk of sudden belt failures. Failure of these serpentine belts can fail the car's power steering system. It may also cease the alternator or water pump.
