Accessory Serpentine Belt Tensioner
00-04 Focus with 2.0 Zetec DOHC I4
A VERY common failure on the Zetec powered Focus. Often they will become "fixed" and immobile, no longer providing tension. Installing our underdrive pullies? Now would be a great time to replace your tensioner, either out of preventative maintenance or to replace a bad one. Vendor can vary - but we only supply quality components - Gates, Litens, Dayco, etc - no china junk.
