2008 Buick Lucerne Belt Tensioner Assemblies

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.

Product Features:

• Endures the toughest conditions while promoting quieter performance and longer life
• Features a steel pivot tube on specific designs for enhanced stability
• Built to outperform and outlast competitive OE parts
• This tensioner is another Dayco product proudly made in the USA

Litens was the Original Equipment (O.E.) supplier of this part and offers this “O.E. Exact”* part for the aftermarket. The Litens product meets all original equipment form, fit, and function specifications for this General Motors application. (*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.) Note: This tensioners has gone through numerous O.E. design modifications throughout the years, This tensioner is the 1st generation and covers all design change levels. New engine bolt included. 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.
• Installation instructions included.
• Heavy Duty Steel Pulley with close tolerance ball bearing pocket and Electro-deposited coating for superior corrosion resistance
• 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.

(Tensioner only) Rigorously tested for a sustained, secure performance by a team of product and quality engineers, Dorman’s Automatic Belt Tensioner Assembly is designed to provide proper tension to a vehicle’s serpentine belt. It incorporates a damping design, torsion spring, and sealing system to ensure the proper functioning of many integral engine components. The Automatic Belt Tensioner Assembly is recommended for replacement when replacing the serpentine belt.

Product Features:

• Quality tests on this part include torque testing, spring-back testing, corrosion-resistance testing, and on-vehicle testing
• Solid steel or aluminum construction for long-lasting durability
• Highly resistant to heat and shock
• Designed to fit properly every time
