Oldsmobile Regency Belt Tensioners

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
• Made in the USA

Litens was the Original Equipment (O.E.) supplier of this popular General Motors water-passage tensioner. This “.OE. Exact”* part for the aftermarket meets all original equipment form, fit, and function specifications. (*OE 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: The base plate cover differs in color from the O.E plate. As the OE supplier, Litens uses sophisticated equipment to pressure test each and every tensioner to ensure leak-free performance. This test is specified by GM and is critical to leak free performance. Most non-OE suppliers do not have this equipment and do not test for leaks. 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”. 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. Tensioner is an integrated component of a large aluminum bracket.
• Installation instructions included.
• Heavy Duty Glass Reinforced Polymer Pulley for optimized dimensional control and running surface durability
• Professional Mechanics will change this tensioner in approx. 1 hour+.
• 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.
