CAUTION: The magnetic timing wheels (1) must not come in contact with magnets (pickup tools, trays, etc.) or any other strong magnetic field. This will destroy the timing wheels ability to correctly relay camshaft position to the camshaft position sensor.






1. Disconnect and isolate the negative battery cable.
2. Remove the air cleaner body and upper intake manifold (2) .





3. Cover the open intake ports (1) to prevent debris from entering the engine.
4. Remove the insulator (2) from the LH cylinder head cover.






NOTE: Mark the variable valve timing solenoid connectors (3 and 4) with a paint pen or equivalent so that they may be reinstalled in their original locations.

5. Disconnect the A/C compressor electrical connector (2).
6. Disconnect the left exhaust variable valve timing solenoid electrical connector (4).
7. Disconnect the left intake variable valve timing solenoid electrical connector (3).
8. Disengage three wire harness retainers (1) from the left cylinder head cover.





9. Disconnect the Engine Coolant Temperature (ECT) sensor connector (3).
10. Disconnect the left Camshaft Position (CMP) sensor (1).
11. Disengage the main wire harness retainer (2) from the cylinder head cover mounting stud.





12. Mark the variable valve timing solenoids (2 and 4) with a paint pen or equivalent so that they may be reinstalled in their original locations.
13. Remove the variable valve timing solenoids






NOTE: The RH CMP sensor is shown, the LH CMP sensor is similar. If removing both RH and LH CMP sensors, mark the sensors so they can be installed in their original locations.

14. Remove the camshaft position sensor





15. Disengage two injection/ignition harness retainers (1) from the left cylinder head cover.





16. Remove the ignition coils (2)





17. Loosen ten cylinder head cover mounting bolts (1) and two studbolts (2) and remove the cylinder head cover.





18. Remove and discard the cylinder head cover gasket (1).
19. The spark plug tube seals (2) can be reused if not damaged.






CAUTION: Do not use oil based liquids, wire brushes, abrasive wheels or metal scrapers to clean the engine gasket surfaces. Use only isopropyl (rubbing) alcohol, along with plastic or wooden scrapers. Improper gasket surface preparation may result in engine fluid leakage.

20. Remove all residual sealant (1) from the cylinder head, timing chain cover and cylinder head cover mating surfaces Procedures
