Dayco 89324 belt tensioner for the 2007 Chevrolet Silverado 2500 HD Classic V8 8.1L and other vehicles takes up slack in the accessory drive belt. The Dayco belt tensioner is an automatic type with one pulley, made for a serpentine belt.
A worn serpentine belt tensioner can show up as belt squeal, a belt that flutters, or a pulley that feels rough or rusty. A worn belt or another pulley can also be behind those signs, so with the engine off and cool, look over the belt for cracks and glazing and the pulley for wobble before replacing anything.
This tensioner also fits the 2007 Chevrolet Silverado 3500 Classic V8 8.1L and the 2007 GMC Sierra 2500 HD Classic V8 8.1L, with one tensioner per truck.
