The Audi S4 was formerly known as Audi 100 S4. During the development of the Audi S4, many popular parts have been built such as the timing belt idler pulley. It is a metal wheel that has a smooth surface and keeps the timing belt in place as it controls the timing gears. The timing belt idler pulley parts are installed through the center of the engine, so the smooth part of the timing belt rotates the pulley to dampen the friction and heat.
Audi S4 stands out for great parts. However, consumers need new timing belt idler pulley parts if they are worn or damaged. The timing belt idler pulley parts are used to help ensure the timing belt is routed correctly. Signs of a worn-out timing belt idler pulley include the belt slipping off the pulley, the pulley no longer spinning, and a squealing noise coming from the pulley.
