• Description:

  This is a Genuine Ford serpentine drive belt, part number 7R3Z-8620-D, for 2006-2008 Ford Mustang equipped with the 4.6L V8 engine. Ford catalog name is Belt - Serpentine. This single multi-ribbed poly-V belt drives the engine's front-end accessories in one continuous loop, routing around the crankshaft pulley, idler pulley, air conditioning compressor, automatic belt tensioner, alternator, power steering pump, and water pump. As the belt ages it loses grip and develops glazing, cracking across the ribs, fraying edges, or chunking, which reduces the drive to those accessories. Drivers who need this belt are often chasing a squealing or chirping noise on startup or under load, a battery or charging warning from a slipping alternator, an overheating engine from a slipping water pump, loss of power steering assist, or visible cracks and missing rib material on the old belt. Because this belt turns the water pump, alternator, and power steering pump together, a failure can quickly leave the engine overheating and without steering assist or charging, so worn belts should be replaced before they break. Inspect the automatic tensioner and idler pulley for smooth, quiet rotation and correct spring tension when installing the new belt, since a weak tensioner or seized pulley will shorten belt life. Route the belt exactly per the factory diagram so every accessory is driven correctly. As a Genuine Ford original-equipment part it matches the correct length, rib count, and profile for the 4.6L V8 accessory drive for a direct fit without modification.
