Dayco 89230 belt tensioner for the 1993-2000 Ford Explorer and other vehicles keeps the drive belt tight against its pulleys. As the belt wears and stretches, the Dayco belt tensioner takes up the slack.
A squealing or chirping belt, belt flutter or a rough-sounding pulley can mean the serpentine belt tensioner is wearing out. Before you replace it, rule out a worn belt or a failing accessory pulley bearing, since either one can make similar noises.
Listed for a wide range of Ford, Mercury and Mazda models, it serves as an Explorer belt tensioner for the 1993-2000 Ford Explorer and also fits the 1994-2000 Ford Ranger V6 4.0L and the 1998-2001 Mercury Mountaineer V6 4.0L. The 1994-2000 Ford Ranger V6 4.0L takes one, and this listing is one tensioner. Other covered models are on the Buyer's Guide tab, so look up your own year and engine there.
