Dayco Accessory Drive Belt P/N:17505
Dayco 17515 accessory drive belt for the 1980-1981 Ford F-150 V8 5.8L, the 1980-1986 F-150 V8 5.0L and other vehicles carries engine power to belt-driven accessories such as the alternator, power steering and air conditioning.
A squeal in normal driving, or cracks and fraying you can see with the engine off, can mean the belt is worn. A squeal alone does not prove the belt is the problem, because a worn pulley or low belt tension can make that noise too.
It also fits the 1980-1981 Ford F-250 V8 5.8L or 6.6L, the 1980-1986 F-250 V8 5.0L and the 1970 Ford Mustang V8 5.0L, and each takes one belt. Many other vehicles are covered as well, so open the "Vehicles it fits" section and look up your exact model and engine.
