Camshaft Position Actuator Solenoid Alignment Procedure

  1. Make an alignment pin from drill rod 15/64 inch diameter and at least 50 mm (1.97 in) long.
  2. Verify that the alignment pin will pass through the CMP actuator solenoid alignment hole.
  3. Verify that the alignment pin will fit into the alignment hole in the CMP actuator oil control valve.
  4. Apply a 2 mm (0.079 in) bead of RTV GM P/N 12378521 (Canadian P/N 88901148) around the flange of the CMP actuator solenoid.
  5. Install the CMP actuator solenoid over the oil control valve.
  6. Install the alignment pin through the solenoid alignment hole and into the oil control valve alignment hole.
  7. With the alignment pin in place, install the CMP actuator solenoid bolts. Tighten: Tighten the CMP actuator solenoid bolts to 8 N.m (71 lb in).
  8. Remove the alignment pin.
  9. Install a NEW CMP actuator solenoid plug.
  10. Connect the electrical connector to the actuator solenoid.
  11. Install the fuel injector sight shield. Refer to «Fuel Injector Sight Shield Replacement»(ref-197575-S37763020362005101200000) in Engine Mechanical - 4.6L (LH2).
