double sided serpentine belt

There are several types of drive belts used in cars, the most common being the serpentine belt and the V-belt. The serpentine belt is a long, continuous belt that winds around multiple engine components, including the alternator, power steering pump, water pump, and air conditioning compressor. It operates by friction, allowing it to drive these accessories simultaneously. The serpentine belt is favored in modern vehicles due to its smaller size, lighter weight, and ability to efficiently power several components at once.

The alternator drive belt, also commonly referred to as the serpentine belt or accessory belt, is a long, looping belt that connects the alternator to the engine's crankshaft. It is responsible for transferring mechanical power from the engine to the alternator, allowing it to generate electricity. In many vehicles, this belt also drives other components such as the power steering pump, water pump, and air conditioning compressor. By powering these essential systems, the alternator drive belt ensures that the vehicle operates efficiently and reliably.
