Belt Tensioner - 999978A

Litens was the Original Equipment (O.E.) supplier of this part and offers this "O.E. Exact"* part for the aftermarket. This popular tensioner designed for Ford Diesel vehicles, looks, fits, and performs like the original part being replaced. "O.E. Exact" - Original Equipment manufacturers prohibits the use of their part number or logo on parts sold to other customers. Therefore, the Litens aftermarket part may have minor cosmetic differences but still be exact in performance and design. Like the original design, this tensioner maintains the molded dual locating pins, a molded lift feature in the arm, and the heavy duty steel pulley. The Tensioner comes complete with a new fastening bolt. Choosing The Correct Replacement Part: Both the original equipment and Litens aftermarket tensioner use a round spring versus a flat spring and are marked "Made in Canada". Caution: Ford Issued a TSB (technical service bulletin) on the part (TSB 12-1-13 issued 1/20/12) warning installers to follow correct belt routing procedures - The belt routes over the upper idler pulley, not under Litens is the world's largest supplier of original equipment (O.E.) power transmission products. At Litens, we design systems that are more efficient, resulting in tangible fuel economy/emissions benefits. Litens holds over 2000 patents and continues to respond to the ever-changing automotive industry by investing heavily in new technology, facilities, and people. 90% of our line is made of products coming from the OE manufacturer, which makes the Litens Tensioning Products portfolio the purest OE tensioning line in the North American aftermarket.Dayco 89658Gates 39153; 780805535Continental 49466
