  • Eliminates belt squeal and vibration due to degraded belt material

Installation Notes and Tips

Ensure the engine is off and cool before beginning installation. Verify the belt routing matches the vehicle’s accessory drive diagram. Inspect pulleys and tensioners for wear or damage prior to installing the new belt. Use appropriate tools to relieve tension on the belt tensioner and carefully position the Roadmax 8K1264AP belt. After installation, double-check belt alignment and tension to prevent premature wear.
