The fan belt is a rubber belt that connects multiple engine components to the vehicle's crankshaft. As the crankshaft turns, it drives the belt, which in turn powers other accessories, ensuring they function correctly. Most modern vehicles use a serpentine belt design, which is longer and can drive multiple accessories with a single belt, making it more efficient than older models with multiple belts.
