Installation Guide

1. Safety First: Ensure the engine is completely cool and disconnect the battery to prevent accidental starting.
2. Locate the Belt: Identify the serpentine belt routing around the various pulleys. It's helpful to sketch or photograph the path.
3. Release Tension: Locate the belt tensioner pulley. Use a ratchet or belt tensioner tool to rotate the tensioner, releasing the pressure on the belt.
4. Remove Old Belt: While the tension is released, carefully slide the old belt off the pulleys.
5. Inspect Pulleys: Before installing the new belt, spin each pulley by hand to ensure they rotate smoothly and are free of damage.
6. Install New Belt: Route the new belt according to your diagram, starting with the crankshaft pulley and leaving the tensioner for last.
7. Apply Tension: Slowly release the tensioner to apply pressure to the new belt. Ensure it sits correctly in the grooves of each pulley.
8. Final Check: Reconnect the battery, start the engine, and observe the belt for a few minutes to confirm it is running smoothly and quietly.
