🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the belt tensioner

• Open the hood and find the automatic belt tensioner on the front of the engine.
• Use a 19mm wrench or 3/8-inch drive breaker bar on the tensioner arm.
• Move slowly and keep control.

Step 2: Relieve belt tension

• Rotate the tensioner in the direction that unloads the belt.
• Keep the tool steady and slide the belt off one smooth pulley, usually an accessible idler or alternator pulley.
• Release the tensioner slowly once the belt is off.

Step 3: Remove the old belt

• Pull the belt out of the engine bay.
• Inspect it for cracks, glazing, missing ribs, or fraying.
• Check every pulley by hand for roughness, wobble, or noise.

Step 4: Route the new belt

• Compare the new belt to the old one to confirm length and rib count.
• Route the belt around all pulleys except the easiest final pulley to access.
• Follow the under-hood routing diagram exactly.
• Make sure the ribs sit fully in every grooved pulley.

Step 5: Install the belt on the last pulley

• Use the 19mm wrench or 3/8-inch drive breaker bar to rotate the tensioner again.
• Slip the belt onto the last pulley while holding the tensioner back.
• Slowly release the tensioner and confirm the belt stays seated.

Step 6: Verify belt alignment

• Inspect each pulley from above to make sure the belt is centered and fully seated.
• Spin the engine by hand only if needed and safe to do so, using the belt path as a final check.
• No fastener torque is required for this job unless you replaced a pulley or tensioner.
