Litens® 999551A Accessory Drive Belt Tensioner Assembly

Serpentine Belt Tensioner

Accessory Drive Tensioner

Automatic Belt Tensioner

Litens was the Original Equipment (O.E.) supplier of this G.M./SAAB/Hummer/Isuzu part for the aftermarket. This O.E. Exact* part for the aftermarket meets all original equipment form, fit, and function specifications. *(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). Both the original and this aftermarket part use Litens patented noose-ring internal damping system not available in aftermarket tensioners from other suppliers. The tensioner is designed with a square lift feature molded into the arm to assist in belt replacement as well as a belt stretch indicator. 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.

Manufactured by the original equipment part supplier to ensure proper form, fit, and performance.

Internal round spring technology to provide constant belt tension and alignment throughout its service life.

Heavy Duty Thermoplastic Pulley. (Note: The pulley on the OE tensioner may be steel or thermoplastic).

Professional Mechanics will change this tensioner in approx. 20 minutes.

Accessory drive belts and tensioners are manufactured with similar design life targets. Since belt removal is required to change the tensioner, replacing both will extend the system service life and lower labor costs versus individual replacement.

Installation instructions included.
