1. Remove the remote power steering reservoir. Refer to Remote Power Steering Fluid Reservoir Replacement.
2. Remove the air conditioning, power steering and water pump drive belt tensioner. Refer to Drive Belt Tensioner Replacement - Air Conditioning, Power Steering, and Water Pump.
3. Disconnect the actuator solenoid electrical connector.
4. Remove the left exhaust camshaft position (CMP) actuator solenoid bolts.
5. Remove the left exhaust CMP actuator solenoid.

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

To allow for CMP actuator solenoid to CMP actuator oil control valve alignment, DO NOT install the NEW CMP actuator solenoid alignment plugs at this time.

1. Make an alignment pin from drill rod 15/64 inch diameter and at least 50 mm (1.97 in) long.
2. If necessary remove the black alignment plug on the actuator and 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.

Caution: Refer to Fastener Caution in the Preface section.

7. With the alignment pin in place, install the CMP actuator solenoid bolts and tighten 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 air conditioning, power steering and water pump drive belt tensioner. Refer to Drive Belt Tensioner Replacement - Air Conditioning, Power Steering, and Water Pump.
12. Install the remote power steering reservoir. Refer to Remote Power Steering Fluid Reservoir Replacement.
