🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the belt and tensioner

• Open the hood and use a flashlight to find the serpentine belt and automatic tensioner.
• Check the belt routing diagram before touching anything.
• Routing photos save time.

Step 2: Relieve belt tension

• Use a 14mm wrench on the tensioner and rotate it to unload the belt tension.
• Keep steady pressure on the wrench while you slip the belt off one smooth pulley, usually the easiest accessible pulley.
• Do not let the tensioner snap back.
• Torque: No fasteners are removed in this step.

Step 3: Remove the old belt

• Slowly release the 14mm wrench and remove the belt from the remaining pulleys.
• Compare the old belt to the new belt to confirm the length matches.
• Look for cracks, missing ribs, or glazing on the old belt. That confirms replacement was due.

Step 4: Route the new belt

• Use the routing diagram and place the new belt around all pulleys except the easiest one to leave for last.
• Make sure the ribbed side of the belt sits fully in every grooved pulley.
• Leave one pulley for last so you can slip the belt on while the tensioner is still released.
• Check each rib by touch.

Step 5: Install the belt on the final pulley

• Use the 14mm wrench again to rotate the tensioner and create slack.
• Slip the belt onto the final pulley with your other hand.
• Slowly release the tensioner so it takes up the belt load.
• Torque: No fasteners are removed in this step.

Step 6: Inspect belt seating

• Use a flashlight to inspect every pulley and make sure the belt is fully seated.
• Look for any twisted sections or ribs sitting outside the grooves.
• If anything looks off, relieve tension and correct the routing before starting the engine.

Step 7: Start and verify

• Start the engine and watch the belt for a few seconds.
• Listen for squealing, chirping, or slapping noises.
• Shut the engine off and recheck the belt if you hear or see anything abnormal.

✅ After Repair
