⚠️ Safety & Precautions

• 🛑 Make sure the hybrid system is OFF (not in READY) before working in the engine bay.
• 🧤 Keep hands/tools away from the belt path; never work near a moving belt.
• 🔥 Let the engine cool; the radiator area and engine can burn you.
• 🧱 Support the car with jack stands on solid, level ground; never rely on a jack alone.
• 🔑 Keep the key fob at least 10 feet away so the system can’t wake up.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift the front-right corner (for access)

• Place wheel chocks behind the rear wheels.
• Use a 21mm socket and breaker bar to slightly loosen the front-right lug nuts (about 1/2 turn).
• Lift the front-right with a floor jack and support with jack stands.
• Remove the wheel using the 21mm socket.

Step 2: Remove the splash shield (inner fender/under cover)

• Use a 10mm socket to remove the small bolts holding the lower/side splash shield.
• Use a trim clip remover to pop out any plastic clips.
• Pull the shield back enough to see the belt and tensioner area.
• Trim clips pry straight out; don’t twist hard.

Step 3: Relieve belt tension

• Locate the belt tensioner (spring-loaded arm with a pulley).
• Put a 19mm wrench on the tensioner pulley bolt.
• Rotate the wrench smoothly to move the tensioner and loosen the belt.
• While holding the tensioner back, slide the belt off one top pulley with your free hand.
• A spring tensioner snaps back fast—hold tight.
• Tool definition: A tensioner is a spring-loaded part that keeps the belt tight automatically.

Step 4: Remove the old belt and check pulleys

• Release the tensioner slowly using the 19mm wrench.
• Pull the old belt out through the wheel-well opening.
• Spin each pulley by hand and feel/listen for roughness or wobble.
• Check the tensioner pulley surface for cracks or missing chunks.

Step 5: Route the new belt

• Compare the new belt to the old one (same length and rib count).
• Route the belt around the pulleys exactly like your photo/sketch, leaving the easiest-to-reach pulley for last.
• Make sure the belt ribs sit fully inside the grooved pulleys (no ribs hanging off an edge).
• Use a flashlight to confirm the belt is centered on every pulley.

Step 6: Apply tension and final alignment check

• Use the 19mm wrench to rotate the tensioner again.
• Slip the belt over the final pulley, then slowly release the tensioner.
• Re-check every pulley alignment by sight and touch.

Step 7: Reinstall splash shield and wheel

• Reinstall the splash shield using the trim clip remover (for clips) and 10mm socket (for bolts).
• Install the wheel and hand-thread lug nuts.
• Lower the car off the jack stands using the floor jack.
• Tighten lug nuts in a star pattern using a torque wrench: Torque to 103 Nm (76 ft-lbs).

✅ After Repair

• 👀 Before starting, do one last visual check that the belt is seated on every pulley.
• 🚗 Start the car and watch the belt for 30-60 seconds; it should run smooth with no wandering.
• 🔊 Listen for squeal, chirping, or slapping noises.
• 🧪 Turn A/C on and off and verify no new noises.
• 🛠️ If it squeals right away, shut it off and re-check belt routing/alignment.
