This automatic belt tensioner assembly is a direct-fit replacement for the listed 1987-1992 Ford Bronco, F-150 and F-250 with the V8-5.0L or V8-5.8L engine, plus a range of Ford E-Series vans — see the Buyer's Guide tab for the full application list.
A worn tensioner often shows up as belt squeal, a rattle or knock from the tensioner area, or accessories that spin unevenly. If a failed or weak tensioner is the cause, this assembly replaces it to restore proper belt tension. Compare the pulley diameter and width against your original before ordering to confirm the match.
