• EPDM compound resists ozone, oil, and high temperatures for longer life
• Polyester cords maintain dimensional stability under load
• Precision top width (0.807 in) and effective length (71.42 in) for accurate tension
• Designed to minimize belt slip, squeal, and accessory misalignment

How should I install and maintain this serpentine belt for best results?

Tool-free installation is possible on many vehicles, but always inspect the tensioner and pulleys for wear before fitting the new belt. Replacing a worn tensioner or idler while installing the belt helps prevent premature failure and keeps accessory loads stable.

• Check tensioner pulley runout and idler bearings for smooth rotation
• Replace any cracked, glazed, or oil-soaked components before finalizing installation
• Follow vehicle-specific routing diagrams and torque specifications
• Perform a test run to verify quiet operation and correct alignment
