• ⚠️ Keep fingers, hair, and clothing away from pulleys at all times.
• ⚠️ Hybrid safety: do not touch orange high-voltage cables/connectors.
• ⚠️ Support the car with jack stands before going under or removing a wheel.
• ⚠️ Battery disconnect is not required for this job, but keep the key far away so the system can’t go READY unexpectedly.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift the front-right corner safely

• Place wheel chocks behind the rear wheels.
• Use a 21mm socket and breaker bar to loosen the front-right lug nuts 1/2 turn (do not remove yet).
• Lift the front-right with a floor jack and set the car on jack stands.
• Remove the wheel using the 21mm socket.
• Reinstall lug nuts later: Torque to 103 Nm (76 ft-lbs)

Step 2: Remove the right-side splash shield for access

• Use a 10mm socket to remove splash shield screws/bolts.
• Use a trim clip removal tool to pop out plastic clips (a clip tool is a small forked pry tool that removes push-clips without breaking them).
• Pull the shield back to expose the belt, pulleys, and tensioner.

Step 3: Relieve belt tension

• Locate the automatic belt tensioner (spring-loaded arm with a pulley).
• Put a 19mm socket on the tensioner’s hex/bolt head.
• Use a breaker bar to rotate the tensioner to relieve tension.
• Hold steady—spring tension is strong.

Step 4: Remove the old belt

• While holding the tensioner released with the breaker bar, slide the belt off the easiest-to-reach pulley.
• Slowly let the tensioner return to its resting position (do not let it snap).
• Remove the belt fully and compare it to the new belt (length and rib count should match).

Step 5: Install the new belt (route it correctly)

• Route the new belt around the pulleys exactly like your photo.
• Make sure the belt ribs sit fully inside the grooves on ribbed pulleys (no ribs hanging off).
• Leave the easiest pulley for last.

Step 6: Apply tension and seat the belt

• Use the 19mm socket and breaker bar to rotate the tensioner again.
• Slip the belt onto the last pulley, then slowly release the tensioner.
• Visually check alignment on every pulley from the side.
• If it’s off by 1 rib, redo it.

Step 7: Reassemble splash shield and wheel

• Reinstall the splash shield using the 10mm socket and any clips you removed.
• Reinstall the wheel using the 21mm socket.
• Lower the car off the jack stands using the floor jack.
• Tighten lug nuts in a star pattern: Torque to 103 Nm (76 ft-lbs)

✅ After Repair

• Start the car and listen: there should be no squeal, slap, or chirp.
• Let it idle for 30-60 seconds while you watch the belt from a safe distance (hands clear).
• Shut it off and re-check belt seating if you notice any noise.
• After a short test drive, do a final quick visual check for alignment.
