Motor pulley is used to add the proper tension to the serpentine belt and to ensure the belt is guided properly through all pulleys. This idler motor pulley does not power any peripheral devices. It is adjustable in several directions to ensure the belt can be properly tensioned, and it is usually in a location that is fairly easy to access for quick and accurate belt tension adjustment. Serpentine belts often feature a flatter series of pulleys, since the belt is not grooved but is instead wider and flatter. The pulleys themselves are made of metal that can withstand the friction created from the belt as well as the high temperatures common in the engine compartment.
