🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the belt and tensioner

• Open the hood and find the serpentine belt at the front of the engine.
• Locate the automatic belt tensioner. This spring-loaded arm keeps the belt tight.
• Use a flashlight if needed to see the pulley path clearly.

Step 2: Release belt tension

• Place a 15mm socket and 1/2-inch drive breaker bar on the tensioner bolt or hex.
• Rotate the tensioner clockwise to unload the belt.
• Move slowly and keep control.

Step 3: Remove the old belt

• With tension released, slip the belt off one easy-to-reach pulley.
• Slowly return the tensioner to its resting position.
• Remove the belt from all pulleys and pull it out of the engine bay.

Step 4: Inspect the pulleys

• Spin each accessible pulley by hand.
• Make sure they turn smoothly and quietly.
• Look for wobble, roughness, or leaking coolant/oil around the belt path.
• If a pulley feels rough, it should be repaired before installing a new belt.

Step 5: Route the new belt

• Compare the new belt to the old one to confirm the length matches.
• Follow the under-hood routing diagram exactly.
• Route the belt around all pulleys except one easy-access pulley for last.
• Keep the belt ribs seated in every grooved pulley.

Step 6: Install the belt on the final pulley

• Use the 15mm socket and 1/2-inch drive breaker bar to rotate the tensioner again.
• Slip the belt onto the last pulley while holding tension off the belt.
• Slowly release the tensioner and confirm the belt sits fully in every groove.

Step 7: Verify belt alignment

• Inspect the full belt path one more time.
• Make sure the belt is centered on each pulley and not riding on a lip.
• Turn the engine by hand only if needed for a final visual check, with ignition off.
