Step 3: Relieving Tension and Removing the Old Belt

Apply Leverage: Attach your breaker bar or serpentine belt tool to the tensioner bolt or square drive.
Rotate the Tensioner: Slowly apply force in the direction specified (clockwise for 4-cylinder, counter-clockwise for V6) until the tension on the belt is released.
Slip Off the Belt: While holding the tensioner open, carefully slip the belt off one of the pulleys (usually the alternator or power steering pump is easiest).
Release Tensioner: Slowly release the tensioner back to its resting position.
Remove Old Belt: Completely remove the old belt from all pulleys. Inspect it for wear and tear – this can give you clues about potential underlying issues.

Step 4: Installing the New Serpentine Belt

This is where your diagram and your photo become invaluable. Follow the routing precisely.

Route the New Belt: Start by routing the new belt around all the stationary pulleys first (crankshaft, water pump, idler pulleys, etc.), leaving the tensioner pulley for last. Make sure the ribs of the belt align perfectly with the grooves on the pulleys.
Double-Check Routing: Compare your new belt’s routing to your diagram and the photo you took. Even one wrong loop can cause the belt to jump off or shred.
Relieve Tension Again: Apply your tool to the tensioner pulley and rotate it to relieve tension.
Slip Belt onto Tensioner: With the tensioner open, carefully slip the new belt over the tensioner pulley.
Release Tensioner Slowly: Gently release the tensioner, allowing it to apply proper tension to the new belt. Ensure the belt stays seated correctly on all pulleys.

Step 5: Final Checks and Test Run

Visual Inspection: Do a thorough visual check of the entire belt path. Ensure it’s perfectly seated on every pulley, with no twists or kinks.
Reconnect Battery: Reconnect the negative battery terminal.
Start the Engine: Start your Accord and let it run for a few minutes. Listen for any squealing or unusual noises. Watch the belt carefully to ensure it’s tracking straight and true on all pulleys.
Check Accessories: Test your power steering, air conditioning, and make sure your battery light isn’t on.
Torque Bolts (if applicable): If you loosened any brackets or components for access, re-torque them to factory specifications.

Congratulations! You’ve successfully replaced your 2006 Honda Accord’s serpentine belt. Take pride in that smooth, quiet engine bay!
