Litens was the Original Equipment supplier (O.E.) of this part and offers this “O.E. Exact”* part for the aftermarket. This popular tensioner designed for General Motors vehicles, looks, fits, and performs like the original part being replaced. Unlike many Non-O.E. aftermarket tensioner suppliers, the Litens part maintains the original equipment steel pulley and internal damping feature for optimal performance and life. Installation Tip: Note the Litens aftermarket tensioner maintains the inset square wrench “lift feature” on the tensioner face to facilitate belt tension release during installation. This lift-feature makes installation easier on the assembly line or in the garage. *OE Exact – Original Equipment manufacturers prohibits the use of their part number or logo on parts sold to other customers. Therefore, the Litens integrated bolt/washer versus 2 separate components. Choosing The Correct Replacement Part: Both the original equipment and Litens aftermarket tensioner use a round spring versus a flat spring. 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.

Product Features:

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. The internal damping design provides quiet, smooth, system performance.
Installation instructions included.
Heavy Duty Steel Pulley
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.

The Dayco automatic belt tensioner features Dayco’s original, patented flat spring design to provide less operating range variation. It reduces the risk of premature accessory bearing failure due to high tension and lessens the risk of belt noise and slippage – or poor performance caused by low tension. A PTFE string wound within the spring resists abrasion and dampens noise. Dayco’s tensioner is also designed with a heavy-duty cast aluminum spring case and arm, which helps resist cracking and fatigue and offers additional strength, lessening the risk of distortion. Additional premium thermoplastic rubber spring slot plugs and rubber O-ring seals help keep contaminants out and zinc coated mounting bolts resist rust.
