Choosing The Correct Replacement Part: Both the original equipment and Litens aftermarket tensioner use a round spring versus a flat spring. Supplied with a new mounting bolt. CAUTION: Some non-original equipment manufacturers have consolidated this part with a similar Ford/Mazda tensioner. They provide a spacer sleeve for the bolt and 2 extra bolts to assist in installation. While the part may be mounted on either engine design, the belt drives require different tension values and the nominal tensioner position once the belt is installed may not be correct.
