Dayco Accessory Drive Belt P/N:17450
Keep your engine's accessories turning with the Dayco accessory drive belt (P/N 15520) — a black V-belt that transfers rotational power from the crankshaft pulley to belt-driven accessories. It loops into place as a direct-fit replacement across a wide range of classic GM, Ford and Mopar applications, including the 1966-1967 Chevrolet Impala 6.5L / 7.0L, the 1980-1985 Chevrolet Impala 3.8L / 5.7L, and the 1977 and 1979-1982 Ford F-150 4.9L. See the "Vehicles it fits" section for the full list.
Squealing, chirping, cracking, glazing, or fraying are signs a V-belt may need replacing. If a worn belt is the cause of those symptoms, this belt replaces it and is designed to drive the accessories it turns. Inspect the belt's routing and tension during installation.
