- Route the new belt around all the pulleys exactly as shown in your 2007 Honda CR-V serpentine belt diagram.
- Leave one pulley (usually an idler pulley or the smooth pulley on the tensioner itself) for last, as this will be where you slide the belt on once tension is relieved.
- Double-check that the belt is seated correctly in all the grooves of every ribbed pulley.
Ensuring correct routing is vital; an improperly routed belt will quickly fail or cause damage.
Step 6: Reapply Tension and Verify
- Using your serpentine belt tool or breaker bar, once again rotate the tensioner arm to relieve tension.
- While holding the tensioner open, carefully slip the new belt over the last pulley.
- Slowly release the tensioner, allowing it to apply pressure to the new belt.
- Remove your tool.
- Visually inspect the entire belt path one more time. Ensure the belt is perfectly seated in all the grooves on every pulley and that there are no twists or misalignments.
Step 7: Final Checks and Test Drive
- Reconnect the negative battery terminal.
- Start the engine. Listen for any squealing, chirping, or unusual noises.
- Watch the belt as it runs for a minute or two, ensuring it tracks smoothly and doesn’t wobble.
