engine belt in car

The serpentine belt operates using the engine's crankshaft pulley as its primary drive. As the engine runs, the crankshaft rotates the belt, which, in turn, engages various accessory pulleys. This movement powers the alternator, which generates electricity for the vehicle’s electrical system and battery. Additionally, the belt drives the power steering pump, enabling easier steering, supports the air conditioning system to keep the cabin cool, and can also power the water pump in some vehicle designs. The continuous action of the serpentine belt ensures that these critical systems function smoothly and efficiently.
