🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the belt routing

• Open the hood and look at the belt routing diagram on the radiator support or underside of the hood.
• If the diagram is missing, take a clear photo of the current belt path before removal.

Step 2: Access the tensioner

• Use a 15mm wrench or breaker bar on the belt tensioner bolt.
• Rotate the tensioner to release belt tension. A breaker bar gives better leverage.

Step 3: Remove the old belt

• Slide the belt off one accessible pulley while holding the tensioner released with the 15mm wrench or breaker bar.
• Slowly let the tensioner return to its resting position.
• Remove the belt from the remaining pulleys by hand.

Step 4: Inspect the pulleys

• Use a flashlight to check every pulley for cracks, wobble, rust, or rough movement.
• Spin each accessible pulley by hand. Replace any pulley that feels rough or noisy before installing the new belt.

Step 5: Install the new belt

• Route the new belt around all pulleys except the easiest final pulley to reach.
• Use the 15mm wrench or breaker bar to rotate the tensioner again.
• Slip the belt onto the last pulley and make sure every rib is seated in every groove.
• Double-check the routing before releasing tension.

Step 6: Verify alignment

• Inspect the belt from above and below if needed.
• Make sure the belt is centered on each pulley and not riding on a flange edge.
• Release the tensioner slowly with the 15mm wrench or breaker bar.

Step 7: Start and test

• Start the engine and watch the belt for a few seconds.
• Listen for squeal, chirping, or pulley wobble.
• Shut the engine off immediately if the belt is misrouted or walking off a pulley.

✅ After Repair
