How do I Replace a 1992 Buick Roadmaster Serpentine Belt?
The 1992 Buick Roadmaster has a single serpentine belt that operates the engine accessories. These accessories include the air conditioner, power steering, water pump and the alternator. The belt is routed around each accessory pulley in a method that is outlined by the serpentine belt routing diagram. As the belt turns around each pulley, it enables each accessory to perform. If the belt is cut, chaffed or has excessive cracking in any area of the belt, replace it immediately before the belt breaks. Once the belt breaks, all the accessories will stop working.
