- Description:
This genuine Ford accessory drive belt is the V-ribbed serpentine belt for the 2011 through 2014 Ford Mustang equipped with the 3.7L V6 engine. Cataloged by Ford as a V-belt and drive belt, it wraps the crankshaft and accessory pulleys to turn the alternator, water pump, and power steering from engine rotation, and its precise rib profile and length maintain correct tension across the drive system. As the belt ages the ribs glaze, crack, and shed material, and the belt stretches, which shows up as a squeal on start-up or under load, a chirp from misalignment, visible cracking or missing chunks, or accessory faults such as a weak charge or intermittent power steering. A worn belt can also slip and reduce water-pump flow, contributing to overheating. Fitting the correct-length belt restores dependable accessory drive and quiet operation. This is the 3.7L V6 application, so confirm your engine. Inspect the tensioner and idler pulleys for smooth, quiet rotation while the belt is off and route the belt exactly per the underhood diagram.
