DAYCO® ela® belts, also known as “stretch” belts, are specifically designed for 2 to 4 point drives that do not require tensioning. Although these belts may look like standard poly rib belts, they are very different. These specially designed belts have self-tensioning capabilities required by specific original equipment (OE) drives designed for a “stretch” belt. Vehicles that are manufactured with “stretch” belts must replace those belts with “stretch” belts. These belts are not interchangeable with standard constructed belts of the 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. Dismounting and reusing stretch belts is not recommended. A new belt should be installed anytime one is removed.

Product Features:

• Wear resistant EPDM rib material
• Highly elastic EPDM cushion rubber that surrounds the polyamide tensile cord
• Designed to elongate over the fixed pulley system
• Provides the proper tension maintenance Related Documents:

This genuine Litens tensioner is manufactured and designed by Litens, the world’s largest manufacturer of belt tensioners. To address shortcomings and common failure points of the original tensioner, Litens has released this new and improved design. A 20% increase in tension results in less noise and belt slip. The main tensioner pivot has been greatly improved to prevent binding frequently experienced with the original part, and a high speed bearing has been implemented to provide long life and reliability. While the appearance is slightly different from the original equipment part, the Litens part meets, and in most cases exceeds, GM’s original form, fit, and function specifications. Note: This drive has experienced issues due to the A/C system. GM issued a Technical Service Bulletin (TSB #01139B/C) suggesting replacement of the A/C compressor to resolve belt jumps and flutter issues). Litens includes a Tech-Tip concerning this issue with the tensioner. Litens is the world’s largest supplier of original equipment (O.E.) power transmission products.
