Installation Guide

1. Preparation: Ensure the engine is cool. Disconnect the battery to prevent accidental starter engagement.
2. Tensioner Adjustment: Locate the belt tensioner pulley. Use a wrench or torque tool to release tension, allowing the belt to slide onto the pulleys.
3. Belt Placement: Route the belt around each pulley in the correct sequence (alternating direction for V‑ribbed belts). Verify that the belt sits snugly on all pulleys without overlapping.
4. Tensioning: Reapply tension by tightening the tensioner until the belt is firmly seated. Check that the belt does not sag or bind.
5. Final Inspection: Inspect for proper alignment, ensure no gaps between ribs and pulleys, and confirm that the belt is free of kinks.

Maintenance Tips

• Inspect the belt every 10,000 km or annually for cracks, fraying, and wear.
• Check tension regularly; a properly tensioned belt should not sag more than 5 mm at its midpoint.
• Avoid exposure to oil leaks or excessive heat sources that could degrade the material.
• Replace the belt if any signs of deterioration appear, even if mileage is below typical replacement intervals.
