Removal

1. Do the battery terminal disconnection procedure. Procedures

2. Disconnect the mass air flow (MAF) sensor/intake air temperature (IAT) sensor connector (A).

3. Disconnect the vacuum hose (B) and breather pipe (C), then remove the intake air duct (D).






4. Remove the engine cover.






5. Disconnect the evaporative emission (EVAP) canister hose (A), the manifold absolute pressure (MAP) sensor connector (B), and the brake booster vacuum hose (C).

6. Remove the harness bracket mounting bolts (D).






7. Disconnect the water bypass hoses (A), then plug the water bypass hoses.

8. Disconnect the throttle actuator connector (B).






9. Remove the front grille cover.






10. Disconnect the fan motor connectors (A), the engine coolant temperature (ECT) sensor 2 connector (B), and the A/C compressor clutch connector (C), then remove the harness clamps (D).






11. Remove the upper brackets and cushions (A), then remove the bulkhead (B).






12. Remove the coolant reservoir (A), then remove the A/C condenser fan shroud (B).

13. Raise the vehicle on the lift.






14. Disconnect the connectors (A), then remove the intake manifold bracket (B).

15. Lower the vehicle on the lift.






16. Remove the intake manifold.






Installation

1. Install the intake manifold (A) with a new gasket (B), and tighten the bolts/nuts in a crisscross pattern in three steps, beginning with the inner bolt.

2. Raise the vehicle on the lift to full height.






3. Install the intake manifold bracket (A), then connect the connectors (B).

4. Lower the vehicle on the lift.
