BMW 550i Serpentine and V Belts

The Driveworks belt is designed to provide better belt-to-pulley contact. The specialized rubber compound incorporates a high temperature polymer formulated to maximize load carrying requirements and belt life. This Driveworks ribbed belt has been constructed and engineered to meet the stringent demands of today’s automotive drive systems. The Driveworks ribbed belt delivers long-lasting dependable belt life.

Product Features:

• Constructed with heat and ozone resistant EPDM rubber
• Fiber is added to the rib stock to reinforce the rubber and reduce noise from worn and misaligned pulleys
• Made with treated polyester cord to reduce belt stretch

Dayco ela self-tensioning belts incorporate 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. The backbone behind the Dayco ela self-tensioning belt is its polyamide tensile member, which allows the high elongation required for installation, yet provides the proper tension maintenance properties to transmit the accessory loads demanded for the drive.

Product Features:

• Designed for two- to four-point drives that do not require automatic or manual tensioning
• Provides self-tensioning capabilities required by specific OE drives designed for a ‘stretch’ belt
• Elasticity allows for long-lasting performance and proper tension

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.

• Utilizes 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
• 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
