Installation Guide

1. Preparation: Disconnect the battery, remove the engine cover, and drain coolant if necessary.
2. Remove Old Belt: Release tension using the hydraulic tensioner lever or tool, then carefully unwind the old belt from all pulleys.
3. Install New Pulleys: Mount the new idler pulleys onto their respective brackets and secure them with bolts.
4. Mount Tensioner: Attach the hydraulic tensioner to its bracket, ensuring proper alignment with the timing gear.
5. Thread New Belt: Route the new belt around all pulleys following the manufacturer’s diagram. Verify correct path and orientation.
6. Tighten Tensioner: Apply hydraulic pressure to set the correct belt tension, then lock the tensioner in place.
7. Final Checks: Re‑install the engine cover, reconnect the battery, and perform a low‑speed test run to confirm smooth operation.

Maintenance Tips

• Inspect the belt for cracks or wear after every 10,000 km (or as recommended by the vehicle manufacturer).
• Check tensioner preload periodically; adjust if the belt shows signs of slack.
• Avoid over‑tightening bolts on pulleys to prevent premature bearing failure.
• Keep the engine bay clean to reduce dust accumulation on the belt and pulleys.
