Dayco Accessory Drive Belt Tensioner Assembly P/N:89204
Dayco 89237 belt tensioner for the 1997-2001 Ford F-150 V8 4.6L or 5.4L and other vehicles holds the accessory drive belt at working tension. It is a Dayco belt tensioner, also called a serpentine belt tensioner, and it takes up slack so the belt stays seated on its pulleys.
A worn tensioner can show up as a chirping or squealing belt, a wobbling pulley or a belt that looks glazed or frayed. Other drive parts can make the same noises, so with the engine off and cool, look over the belt, the arm and the pulley for cracks, rust or play first. This listing is one tensioner, and the fitment calls for one per vehicle.
The 1997-2001 Ford F-150 V8 4.6L or 5.4L, the 1997-2002 Ford Expedition V8 4.6L or 5.4L and the 1997-1999 Ford F-250 V8 4.6L or 5.4L all take this tensioner, and so do many other vehicles.
