    Install the crankshaft sprocket (1) onto the front of the crankshaft. Align the crankshaft key with the crankshaft sprocket keyway.

  2. GM2911792Courtesy of GENERAL MOTORS COMPANY

    Rotate the crankshaft sprocket until the sprocket alignment mark (1) is in the 12 o'clock position.

  3. GM2911795Courtesy of GENERAL MOTORS COMPANY

    Compress the timing chain tensioner guide and install the EN 46330  pin (1).

    CAUTION:

    Refer to Fastener Caution .

    Install the timing chain tensioner and left side bolt (1). Do not install the right side bolt at this time. The right side bolt will be installed after the camshaft position (CMP) actuator and chain have been installed onto the engine.

    Remove the tie strap (1) from the actuator.

    NOTE:

    The alignment mark on the CMP actuator and the alignment mark on the crankshaft sprocket are off-center from the oil pump feed hole gasket on the timing chain tensioner. The alignment marks need to be lined up with one another, but NOT with the oil feed hole.

    The camshaft and the crankshaft sprocket alignment marks MUST be aligned properly.

    If the alignment marks on the CMP actuator and crankshaft sprocket are difficult to see or line up, an alternate method can be used. Mark the gear tooth directly opposite of the alignment mark on the CMP actuator (a). Mark the gear tooth directly opposite of the alignment mark on the crankshaft sprocket (b).

    The timing chain has 30 links. Place links (1) and (30) on either side of the mark made on the CMP actuator and place links (15) and (16) on either side of the mark made on the crankshaft sprocket. This will ensure that the factory alignment marks are in the correct position and that the engine is properly timed.

    NOTE:
    • Properly locate the CMP actuator onto the locating pin of the camshaft.
    • The sprocket teeth and timing chain must mesh.
    • The camshaft and the crankshaft sprocket alignment marks MUST be aligned properly.
    • Do not use the CMP solenoid valve again. Install a NEW valve during assembly.

    Identify the alignment hole (1) in the rear face of the CMP actuator and the locating pin (2) on the front face of the camshaft.

  10. GM1714942Courtesy of GENERAL MOTORS COMPANY

    Install the CMP actuator and timing chain. Align the hole in the rear face of the CMP actuator with the locating pin on the front face of the camshaft. If necessary, rotate the camshaft or crankshaft sprockets in order to align the timing marks. Use care to install the actuator completely onto the front of the camshaft. Position fingers onto the face of the actuator sprocket and push the actuator onto the front of the camshaft. Never push on the reluctor wheel when attempting to install the actuator.

    CAUTION:

    This vehicle is equipped with torque-to-yield or single use fasteners. Install a NEW torque-to-yield or single use fastener when installing this component. Failure to replace the torque-to-yield or single use fastener could cause damage to the vehicle or component.

    Install a NEW CMP actuator solenoid valve (1). With the CMP actuator properly positioned onto the camshaft, the CMP actuator solenoid valve can be threaded completely into the camshaft using light hand pressure. Tighten by hand until snug.

    1. Tighten a first pass to 65 N.m (48 lb ft).
    2. Tighten a final pass an additional 90 degrees using EN-45059  angle meter.

    NOTE:

    It is possible to push the camshaft rearward when installing the CMP valve. Verify that the camshaft lobes are centered in the valve lifter bores after the CMP actuator is installed.

    Locate a straight edge across the front face of the engine block and inspect for proper installation of the CMP actuator and timing chain. With the CMP actuator properly and completely installed onto the front of camshaft, the timing chain will not protrude beyond the front face of engine block.

  13. GM1670623Courtesy of GENERAL MOTORS COMPANY

    Inspect the sprockets for proper alignment. The mark on the CMP actuator sprocket (1) should be located in the 6 o'clock position and the mark on the crankshaft sprocket (2) should be located in the 12 o'clock position.

  14. GM2911802Courtesy of GENERAL MOTORS COMPANY

    Install the right side bolt (1) into the timing chain tensioner and tighten both bolts to 25 N.m (18 lb ft).

  15. GM2911804Courtesy of GENERAL MOTORS COMPANY

    Remove the EN 46330  pin.
