• 🛑 Work on a cool engine; keep hands clear of pulleys.
• 🛑 Support the car with jack stands if you remove the RF wheel; never rely on a jack.
• 🛑 Keep the key away from the car so no one can start it during the job.
• 🛑 Battery disconnect is not required, but avoid touching the starter/positive terminal areas with tools.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the right-front wheel (recommended for access)

• Use a 21mm socket and breaker bar to slightly loosen the RF lug nuts (about 1/2 turn) while the tire is on the ground. A breaker bar is a long handle that helps loosen tight bolts.
• Use a floor jack to lift the RF corner at the factory jacking point, then place jack stands under a safe support point.
• Use the 21mm socket to remove the lug nuts and remove the wheel.
• Reinstall later and Torque to 103 Nm (76 ft-lbs) using a torque wrench.

Step 2: Remove the RF inner splash shield section (to reach the belt)

• Use a trim clip removal tool and flat blade screwdriver to remove the plastic clips/fasteners at the front/side of the RF wheel well splash shield.
• If any 10mm bolts are present, remove them with a 10mm socket and 3/8" ratchet.
• Pull the splash shield back enough to see the belt and tensioner area.

Step 3: Locate the belt tensioner and release belt tension

• Find the automatic belt tensioner (spring-loaded arm with a pulley). It keeps the belt tight automatically.
• Put a 19mm socket on the tensioner’s hex/bolt head and attach the breaker bar.
• Rotate the tensioner smoothly to relieve tension (hold it firmly—spring force is strong).
• While holding tension released, slide the belt off one easy-to-reach pulley (usually the alternator pulley) by hand.

Step 4: Remove the old belt and inspect pulleys

• Release the tensioner slowly with the breaker bar after the belt is free.
• Remove the belt fully from all pulleys by hand.
• Spin each pulley by hand and check for roughness/noise or wobble (no tools needed).
• If a pulley wobbles, stop and ask.

Step 5: Route the new belt correctly

• Compare the new belt length and rib count to the old belt (by hand).
• Route the new belt around the pulleys following the under-hood belt routing diagram (or your photo).
• Make sure the ribbed side sits fully in the grooved pulleys and the flat side sits on smooth pulleys.

Step 6: Apply tension and seat the belt

• Use the 19mm socket and breaker bar to rotate the tensioner again and slip the belt over the last pulley.
• Slowly release the tensioner with the breaker bar so it tightens the belt.
• Visually check every pulley: the belt must be centered and fully seated in the grooves.

Step 7: Reinstall splash shield and wheel

• Reposition the splash shield and reinstall clips using the trim clip removal tool and flat blade screwdriver.
• If removed, reinstall any bolts using a 10mm socket and 3/8" ratchet.
• Reinstall the wheel and hand-thread lug nuts.
• Lower the car with the floor jack, then use a torque wrench to Torque to 103 Nm (76 ft-lbs) in a star pattern.

✅ After Repair

• Start the engine and watch the belt for 20-30 seconds; it should run straight with no wobble.
• Listen for squeal or chirping. If you hear noise, shut it off and re-check belt seating on every pulley.
• Turn A/C on and headlights on to load the system; re-check for noise.
