STS AWD V8-4.6L VIN A (2006)
4. Important: 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.
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:
1. Make an alignment pin from drill rod 15/64 inch diameter and at least 50 mm (1.97 inch) long.
2. Verify that the alignment pin will pass through the camshaft position actuator solenoid alignment hole.
3. Verify that the alignment pin will fit into the alignment hole in the camshaft position actuator oil control valve.
4. Apply a 2 mm (0.079 inch) bead of RTV GM P/N 12378521 (Canadian P/N 88901148) around the flange of the camshaft position actuator
solenoid.
5. Install the camshaft position 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 camshaft position actuator solenoid bolts.
^
Tighten the camshaft position actuator solenoid bolts to 8 Nm (71 inch lbs.).
8. Remove the alignment pin.
9. Install a NEW camshaft position actuator solenoid plug.
10. Repeat steps 4 through 9 for the exhaust camshaft position actuator solenoid.
6. Install the right camshaft cover.
7. Install the right intake camshaft sensor.
8. Install the right exhaust camshaft sensor.
9. Install the camshaft sensor harness to the retainers.
10. Install the fuel injector sight shield.
