1988-02 Idler/Tensioner Pulley

Belt tensioners are engineered so that the belt remains at nearly a constant tension throughout the entire operating range. This ensures maximum accessory drive component life while still preventing belt slip.

Tensioners have an operating ran ge plus extra travel for loading. Belt tension will only be correct if the belt length is correct and the indicator is within operating range.

Tensioners also help to damp the belt and accessory vibrations. Once a "dealer only" item, this tensio ner has now been brought to the aftermarket. This Goodyear Accu-DRIVE™ tensioner features better than OE fit and performance.
