Dayco 89014 accessory drive belt idler pulley for the 1993-1995 Ford Mustang V8 5.0L, the 1996-1999 Mustang V8 4.6L and other vehicles guides the drive belt along its path around the engine's accessories. This Dayco accessory drive belt idler pulley goes in the air conditioning bypass position and spins freely as the belt runs over it.
A squeal or chirp from the belt area, a wobbling pulley, or a gritty feel when you spin the pulley by hand with the engine off and cool can point to a worn idler. A worn belt, a weak tensioner or a rough bearing in the alternator or A/C compressor can be behind those noises too, so find the source before buying.
The 1988 Chevrolet C1500 V8 5.7L, the 1988-1995 C1500 V8 5.0L, the 1990-1995 C1500 V6 4.3L or V8 5.7L, the 1988 Chevrolet K1500 V8 5.7L, the 1988-1995 K1500 V8 5.0L and the 1990-1995 K1500 V6 4.3L or V8 5.7L all fit this pulley, and so do many other vehicles. This listing is one pulley, and the 1993-1995 Ford Mustang V8 5.0L takes one. Driving something else? Look up its year, model and engine in the "Vehicles it fits" section.
