What is a Drive Belt?

Also known as the “V belt” (or serpentine belt), the drive belt transfers “drive” to your air conditioning, alternator and power steering while the engine is going. Many cars have multiple drive belts, depending on the number of accessories fitted to the vehicle’s engine, and these belts are connected to the crankshaft pulley, which turns the belt creating power. As the belt drives the alternator (amongst other things), which in turn charges the vehicle’s battery, the drive belt plays a critical role in the function of your engine.
