Tighten the 13mm bolt to lock the slotted portion in the bracket.
2. Remove the Belt
Pay attention to its position; take photos or make a diagram for reference.
Remove the belt from the pulleys, starting with those on the backside.
3. Inspect and Compare Belts
Ensure the old and new belts are the same size.
Replace the belt if it shows signs of cracking for reliability and safety.
4. Tensioner Replacement
Remove the cap on the pivoting pulley, then the 13mm bolt.
Remove the tensioner by taking off the two 13mm fasteners.
Pair up the old and new tensioner to ensure correctness.
Install the new tensioner mechanism and then onto the engine.
5. Remove the AC Compressor Belt
Access the tension from the underside of the vehicle.
Loosen the 13mm bolt and the 10mm for the slotted bracket.
Pull back the tension, lock the 10mm bolt, and remove the belt.
6. Replace the Pulley if Needed
Replace the pulley if it shows signs of wear or noise.
Pair up the old and new belts and install them, ensuring proper orientation.
7. Install the Final Outer Belt
Ensure proper routing and installation on ribbed and smooth pulleys.
Push the serpentine belt in from the smooth side; it should flex about 1/2".
8. Final Tightening
Tighten the belt to the specified specifications.
9. Check and Start the Engine
Ensure the belt is centered on each pulley.
Start the engine and let it idle for at least 60 seconds to ensure correct operation.

Use a ratchet, breaker bar, or serpentine belt tensioning tool to push the tensioner towards the front of the vehicle.
Slip the belt off the pulleys.
Step 4: Belt Inspection and Removal
Inspect the old belt for wear, and compare it to the new one for size verification.
Remove the old belt by slipping it off the pulleys.
Step 5: Tensioner and Pulley Replacement
If needed, replace the tensioner and pulley.
Install the new tensioner mechanism and secure it back onto the engine.
Step 6: AC Compressor Belt Removal
Access the AC compressor belt tensioner from underneath.
Loosen the bolts, release tension, and remove the belt.
Step 7: Installing the New Belt
Begin by placing the new belt around the crankshaft pulley.
Tuck it around the tensioner, air conditioner, and alternator.
Tension the belt using a ratchet or a serpentine belt tensioning tool.
