Tools required:

  • T25 Torx Driver

  • 10mm socket/ratchet

  • 15mm socket/ratchet

  • 3/8 Drive ratchet handle

  • Flathead screwdriver

Step 1: Open the vehicle's hood.

Step 2: Using the flathead screwdriver, loosen and remove the clamps (2) at each end of the air intake hose. Also, loosen and remove the 10mm bolt (1). Loosen and remove the T25 Torx screws (2) that secure the top of the air box to the assembly. You can now pull the hose/air box cover from the vehicle. Disconnect the wiring harness (1).

Step 3: Loosen and remove the 10mm bolts (2) that secure the bottom of the air box to the engine. You can now lift and remove the rest of this assembly.

Turn the tensioner COUNTER CLOCKWISE, releasing the tension on the belt. You can now remove the belt from the upper pulley. SLOWLY release the tensioner to its resting position.

Step 5: Loosen and remove the 15mm bolts (2) that secure the bracket to the assembly. You can now slide the bracket aside and remove the belt.

Step 6: Using the routing diagram posted near the belt assembly, on the UNDERSIDE of the hood, or in the owner's manual, route the belt around the proper pulleys.

Step 7: Once the belt is in place, turn the tensioner (with the 3/8 ratchet) CLOCKWISE, increasing tension on the belt, securing its position.

NOTE: The belt should be taut, but not overly tight or stretched.

Step 8: Tighten the 15mm bolts (2) to secure the bracket to the assembly.

Step 9: Mount the air box by tightening the 10mm bolts (2). Connect the top of the air box assembly by tightening the T25 Torx screws (2).
