Dayco Accessory Drive Belt P/N:17725
Dayco 17540 accessory drive belt for the 1981-1985 Ford F-150 V8 5.8L and other vehicles transfers engine rotation to the accessories it drives. This Dayco accessory drive belt is a bottom cog belt made of a synthetic rubber compound.
Cracks, fraying, glazed surfaces or a squeal from the front of the engine can mean the belt is worn, though a weak tensioner or a rough pulley can be behind the same signs, so look at those two before you buy. Each engine takes one belt.
The 1981-1985 Ford F-150 V8 5.8L, the 1981-1985 Ford F-250 V8 5.8L and the 1964-1967 Ford Mustang V8 4.7L all fit this belt, as do a wide range of other vehicles. If your vehicle isn't named here, enter its year, make and engine on the Buyer's Guide tab to see whether it matches.
