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
• Meets or exceeds OE quality

This Litens belt tensioner is supplied by the original equipment (O.E.) tensioner supplier and meets all form, fit, and performance characteristics of the original equipment part (with the exception of not having the car manufacturer’s logo or part number applied to the part). As with the original equipment part, this replacement tensioner is manufactured in Germany for BMW engine applications. The tensioner maintains the O.E. round spring technology as well as a heavy duty polymer pulley for optimum performance and durability. To assist with belt removal and installation, this tensioner is equipped with a lift feature and pin that holds the tensioner open during belt routing. 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
• Exposed “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 Polymer Pulley with cap
• Professional Mechanics will change this tensioner in about 1 hour
• Due to the fact that belts and tensioners have similar Original Equipment “design life targets”, it is often a best practice to replace the belt tensioner when replacing a worn or broken belt. Belt removal is required to change the tensioner. Therefore, d

Dayco ela (elastic) or stretch belts are specifically designed for two, three, and four point drives that are designed to use self-tensioning belts. Although these belts may look like standard poly rib belts, they are very different. These specially designed elastic belts have self-tensioning capabilities required by specific OE drives. Vehicles that are manufactured with stretch belts must replace them with stretch belts. These belts are not interchangeable with standard constructed belts of their same size. Dayco ela belts utilize a proprietary EPDM construction that is designed to elongate over the fixed pulley system, and then maintain the required belt tension over the life of the belt. The backbone behind the Dayco ela belt is its specially developed polyamide tensile member, which allows for high elongation required for installation, yet provides the proper tension maintenance properties to transmit the accessory loads demanded for the drive. This belt construction incorporates a wear resistant EPDM rib material, along with a highly elastic EPDM cushion rubber that surrounds the polyamide tensile cord, thus providing the required adhesion and flexibility to maintain lasting performance. Stretch belts have unique installation instructions depending on the OE application. Installation may require a specialized tool for the application or a simple zip tie. Do not attempt to install by prying the belt on the pulleys. Dayco provides detailed instructions on the reverse side of the sleeve.
