Alternator Belt
The alternator belt is a belt that transfers the engine's rotational energy to the alternator. The belt wraps around a complex pulley connected to the crankshaft. As the engine starts and the crankshaft rotates, the belt moves, transmitting rotational energy to the alternator. The alternator, which is a type of generator, converts this energy into electricity and charges the battery to supply power to various parts of the vehicle.
Although the primary function of the alternator belt, as its name suggests, is to transfer rotational force from the engine to the alternator, in modern cars, the timing belt and the alternator belt also drive other engine components such as the water pump, power steering pump, oil pump, air conditioning compressor, and more.
