1. Disconnect and isolate the negative battery cable (1).





2. Lift the engine cover retaining grommets off the ball studs and remove the engine cover (1).





3. Disconnect the electrical connector (1) from the Inlet Air Temperature (IAT) sensor.
4. Loosen the clamp (2) at the throttle body.
5. Loosen the clamp (3) at the air cleaner housing.
6. Lift the air inlet hose assembly retaining grommet off the ball stud (4).
7. Remove the air inlet hose assembly (5).





8. Disengage the brake booster hose retainer (1) from the upper intake manifold.





9. Disconnect the electrical connectors from the Manifold Absolute Pressure (MAP) sensor (2) and the Electronic Throttle Control (ETC) (4).
10. Disengage the ETC harness from the clip (5) on the throttle body and unfasten the wire harness retainer (1) from the upper intake manifold near the MAP sensor and reposition the wire harness.
11. Disconnect the following hoses from the upper intake manifold:
- Positive Crankcase Ventilation (PCV) (7)
- Brake booster vacuum hose (6)
- EVAP vapor purge line (3)





12. Unfasten the wire harness retainer (4) from the upper intake manifold support bracket (2) stud retainer (3).
13. Remove the two nuts (1), loosen the stud (3) and reposition the upper intake manifold support bracket (2).





14. Remove the heater core return tube upper support bracket retaining nut (2) and reposition tube (1).





15. Remove the two nuts (1), loosen two stud retainers (3) and reposition the two upper intake manifold support brackets (2).






NOTE: The upper intake manifold attaching bolts are captured in the upper intake manifold. Once loosened, the bolts will have to be lifted out of the lower intake manifold and held while removing the upper intake manifold.

NOTE: Exercise care not to inadvertently loosen the two fuel rail attachment bolts that are in close proximity of the upper intake manifold attaching bolts.

16. Remove the seven manifold attaching bolts (1) and remove the upper intake manifold (2).





17. Remove and discard the six upper to lower intake manifold seals (1).
18. Cover the open intake ports to prevent debris from entering the engine.
19. If required, remove the insulator (2) from the left cylinder head cover.
