Dayco Accessory Drive Belt Idler Pulley P/N:89570
Dayco 89057 accessory drive belt idler pulley for the 1995-1996 Ford F-250 V8 7.3L and other vehicles guides the serpentine belt on a grooved face. An idler pulley only redirects the belt; it does not drive an accessory.
A squeal or chirp from the belt area, or a pulley that wobbles, can mean the bearing is wearing. With the engine off and cool, turn the pulley by hand. If it spins smoothly and quietly, look at the belt and tensioner before replacing it.
The 1995-1996 Ford F-250 V8 7.3L, the 2000 Ford Excursion V8 7.3L and the 1995-1997 Ford E-350 Econoline Club Wagon V8 7.3L are among the vehicles this pulley fits. The 2000 Ford Excursion V8 7.3L takes one. If your truck or van is not named here, enter its year and model in the "Vehicles it fits" section to see whether it is covered.
