Removal Procedure

    Object Number: 1852296 Size: SH
  1. Remove the left exhaust camshaft actuator. Refer to Camshaft Position Actuator Replacement - Bank 2 (Left Side) Exhaust .
  2. Remove the intake camshaft position actuator bolt.
  3. Remove the left intake camshaft position actuator.

Installation Procedure

    Object Number: 1852294 Size: SH
  1. Ensure the proper camshaft position actuator is installed. Observe the body of the camshaft position actuator for the IN marking (3).

    2. The marking is for an intake camshaft position actuator.


    Object Number: 1853919 Size: SH

    Notice: Ensure the proper camshaft position actuator is installed in the correct position. Failure to install the proper camshaft position actuator can effect engine performance and set an engine code.

  2. Ensure the proper camshaft position actuator is being installed. The reluctor wheel on the right intake camshaft position actuator (1) is indexed in a different position compared to the left intake camshaft position actuator (2).

    3. Object Number: 1853928 Size: SH
  3. On the left intake camshaft actuator the edge of the reluctor wheel (1) lines up with the peak (2) of the sprocket tooth.

    5. The circle marking is for alignment to the highlighted timing chain link on the left side of the engine.

    Notice: Refer to Torque Reaction Against Timing Drive Chain Notice in the Preface section.

  5. Use an open wrench on the hex cast into the camshaft in order to prevent camshaft rotation when tightening the camshaft position actuator bolt.

    6. Object Number: 1852296 Size: SH
  6. Locate the intake camshaft position actuator to the camshaft and loosely install the bolt.

    7. Notice: Refer to Torque Reaction Against Timing Drive Chain Notice in the Preface section.
