Well, it won't keep your pants up, but it does transport power to your vital automotive components. The serpentine belt is one long, snaking, winding belt that keeps your alternator, power steering pump, air conditioning and—in some cases—your water pump running smoothly and effectively. If you suspect your serpentine belt is failing, watch out for the following symptoms: Squealing noise from the front of the vehicle. If you notice a squealing noise coming from the front of your vehicle, it could be from the serpentine belt. Power steering and AC not working. Engine overheating. Cracks and wear on the belt. The serpentine belt is a long, winding belt that connects many of your vehicle's components, including the power steering pump, alternator, and air conditioning compressor, and more, to the vehicle's crankshaft pulley. In some engines, the serpentine belt also runs the water pump, radiator fan, and supercharger. A broken serpentine belt leads to a sudden loss of power assist for the steering system, where the steering wheel all-of-a-sudden becomes very hard to turn. Some cars have the water pump driven off the timing belt and some cars have more than one serpentine belt, so which accessories would work and which wouldn't would vary depending upon your car and which serpentine belt was broken.. It is best to not drive a car with a broken belt, even for a short distance.
