  1. Remove the fuel injector sight shield. Refer to Fuel Injector Sight Shield Replacement.
  2. Remove the throttle body. Refer to Throttle Body Assembly Replacement.

    3. Object Number: 1234875 Size: SH
  3. Loosen the intake manifold duct clamp (1).

    4. Object Number: 1286421 Size: SH

    Note: Note the location of the water outlet housing bolts.

  4. Remove the bolts (1, 2) securing the water outlet housing to the cylinder heads.

    5. The water outlet housing uses two different size bolts. The two bottom bolts are approximately 10 mm (0.39 in) longer than the two upper bolts.

  5. Reposition the water outlet housing forward in order to gain access to the camshaft position actuator housing bolts.
  6. Discard the water outlet housing gaskets.

    7. Object Number: 928266 Size: SH
  7. Remove the right exhaust camshaft sensor. Refer to Camshaft Position Sensor Replacement - Bank 1 (Right Side) Exhaust.
  8. Remove the right intake camshaft sensor. Refer to Camshaft Position Sensor Replacement - Bank 1 (Right Side) Intake.
  9. Remove the right camshaft cover. Refer to Camshaft Cover Replacement - Right Side.
  10. Remove the cam sensor harness from the retainers.

    11. Object Number: 1276389 Size: SH
  11. Remove the right intake camshaft position actuator solenoid bolts.
  12. Remove the right intake camshaft position actuator solenoid.
  13. Remove the right intake camshaft position actuator solenoid alignment plug and discard.

    14. Object Number: 1276390 Size: SH
  14. Remove the right exhaust camshaft position actuator solenoid bolts.
  15. Remove the right exhaust camshaft position actuator solenoid.
  16. Remove the right exhaust camshaft position actuator solenoid alignment plug and discard.

    17. Object Number: 1276305 Size: SH
  17. Remove the right camshaft position actuator housing bolts.
  18. Remove the right camshaft position actuator housing.

Installation Procedure

    Object Number: 1040910 Size: SH
  1. Install a NEW gasket to the camshaft position actuator housing.

    2. Object Number: 1276305 Size: SH
  2. Install the right camshaft position actuator housing to the right cylinder head.

    3. Caution: Refer to Fastener Caution in the Preface section.

  3. Install the actuator housing bolts and studs and tighten to 10 N·m (89 lb in).

    4. Object Number: 1276389 Size: SH

    Note: The camshaft position actuator solenoids must be precisely aligned to the camshaft position actuator oil control valves on the end of the camshafts. This is accomplished with an alignment pin. Failure to align the camshaft position actuator solenoids to the camshaft position actuator oil control valves can lead to poor engine performance and engine component damage.

  4. To allow for camshaft position actuator solenoid to camshaft position actuator oil control valve alignment, DO NOT install NEW camshaft position actuator solenoid alignment plugs at this time.
  5. Use the following procedure for the camshaft position actuator solenoid alignment:
    6. 5.1. Make an alignment pin from drill rod 15/64 inch diameter and at least 50 mm (1.97 in) long.
    5.2. Verify that the alignment pin will pass through the camshaft position actuator solenoid alignment hole.
    5.3. Verify that the alignment pin will fit into the alignment hole in the camshaft position actuator oil control valve.
    5.4. Apply a 2 mm (0.079 in) bead of RTV around the flange of the camshaft position actuator solenoid. Refer to Adhesives, Fluids, Lubricants, and Sealers for the correct part number.
    5.5. Install the camshaft position actuator solenoid over the oil control valve.
    5.6. Install the alignment pin through the solenoid alignment hole and into the oil control valve alignment hole.
    5.7. With the alignment pin in place, install the camshaft position actuator solenoid bolts and tighten to 8 N·m (71 lb in).
    5.8. Remove the alignment pin.
    5.9. Install a NEW camshaft position actuator solenoid plug.
    5.10. Repeat steps 4 through 9 for the exhaust camshaft position actuator solenoid.
  6. Install the right camshaft cover. Refer to Camshaft Cover Replacement - Right Side.

    7. Object Number: 928266 Size: SH
  7. Install the right intake camshaft sensor. Refer to Camshaft Position Sensor Replacement - Bank 1 (Right Side) Intake.
  8. Install the right exhaust camshaft sensor. Refer to Camshaft Position Sensor Replacement - Bank 1 (Right Side) Exhaust.
  9. Install the camshaft sensor harness to the retainers.
  10. Install NEW water outlet housing gaskets.
  11. Install the water outlet housing to the vehicle.

    12. Object Number: 1286421 Size: SH
  12. Install the water outlet housing bolts (1, 2) and tighten to 25 N·m (18 lb ft).

    13. Object Number: 1234875 Size: SH
  13. Install the intake manifold duct clamp (1) and tighten to 6 N·m (53 lb in).
  14. Install the throttle body. Refer to Throttle Body Assembly Replacement.
  15. Install the fuel injector sight shield. Refer to Fuel Injector Sight Shield Replacement.
