Installation Guide

1. Disconnect the battery negative terminal and ensure the engine is completely cool before starting work.

6. Use the tensioner tool to apply proper tension to the belt according to manufacturer specifications.
7. Double-check that the belt is correctly aligned on all pulleys and not twisted.
8. Rotate the engine by hand (if possible) to verify smooth belt operation and proper tracking.
9. Reconnect the battery and start the engine. Listen for unusual noises that may indicate misalignment.
10. Inspect belt tension after the first few hours of operation and adjust if necessary.
