Replacing the serpentine belt on your Equinox means removing tension from the belt tensioner, slipping the old belt off, and routing the new belt correctly. This belt drives key accessories, so a worn or cracked belt should be replaced right away.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove any access panels

• If the lower splash shield blocks access, use the appropriate socket or fastener tool to remove it and set it aside.
• Keep all clips and fasteners organized so they go back in the same places.

Step 2: Locate the belt tensioner

• Use a flashlight to find the spring-loaded belt tensioner at the front of the engine.
• Look at the belt path now so you can route the new belt the same way.

Step 3: Release belt tension

• Use a breaker bar with a 15mm socket on the tensioner bolt or hex drive.
• Rotate the tensioner slowly in the correct direction to release tension from the belt.
• Tip: Move smoothly to avoid slipping.

Step 4: Remove the old belt

• While holding the tensioner released, slip the belt off one smooth pulley, then slowly let the tensioner return.
• Remove the belt from the remaining pulleys by hand.

Step 5: Inspect the pulleys

• Spin each accessible pulley by hand and listen for roughness or grinding.
• Check the tensioner arm for smooth movement and strong spring pressure.
• If a pulley wobbles, squeals, or feels rough, replace that part before installing the new belt.

Step 6: Route the new belt

• Route the new belt around the pulleys exactly as shown by your routing path.
• Leave the easiest-to-reach smooth pulley for last so you can slip the belt on with the tensioner released.
• Tip: The ribs must sit fully in every grooved pulley.

Step 7: Apply tension and finish installation

• Use the breaker bar with the 15mm socket again to release the tensioner.
• Slip the belt onto the last pulley, then slowly release the tensioner.
• Check that the belt is centered on every pulley and not twisted.

Step 8: Reinstall access panels

• If you removed the splash shield, reinstall it now using the original fasteners.
• If any clips are broken, replace them so the shield stays secure.
