Dayco Accessory Drive Belt Tensioner Assembly P/N:89655
Dayco 89607 belt tensioner for the 2007-2011 Jeep Wrangler holds tension on the serpentine belt that drives the engine accessories. The Dayco automatic belt tensioner, also called a serpentine belt tensioner, takes up belt slack so the drive can run without slipping.
A squealing or chirping belt drive, visible belt wear or a pulley with play can mean this belt tensioner is worn, though a worn belt or a failing idler pulley can be behind the same signs.
As a belt tensioner for the 2007-2011 Jeep Wrangler it is a direct-fit replacement, and the engine's belt drive takes one.
