Installation Guide

1. Safety First: Ensure the engine is off and cool. Disconnect the battery's negative terminal to prevent accidental starting.
2. Locate the Belt: Identify the existing circulation pump drive belt and note its routing path around the pulleys. Taking a photo can be helpful.
3. Release Tension: Use the appropriate tool to loosen the belt tensioner pulley, releasing tension on the belt.
4. Remove Old Belt: Carefully slip the old belt off the pulleys.
5. Inspect Components: Before installing the new belt, spin each pulley by hand. They should turn smoothly without wobble or noise. Clean any debris from the pulley grooves.
6. Install New Belt: Route the new belt according to the path noted earlier. Ensure the ribbed side correctly engages with grooved pulleys.
7. Apply Tension: Re-engage the tensioner to apply the correct tension to the new belt. Consult your service manual for specific tension specifications.
8. Final Check: Verify the belt is properly seated in all pulley grooves and correctly aligned. Reconnect the battery.
9. Test Operation: Start the engine and run it for a few minutes, visually confirming the belt is tracking correctly and listening for any unusual noises.
