    GM5608828Courtesy of GENERAL MOTORS COMPANY
    NOTE:

    The alignment mark on the camshaft position actuator (2) and the alignment mark on the crankshaft sprocket (1) 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.

  9. If the alignment marks on the camshaft position actuator (1) and crankshaft sprocket (2) 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 camshaft position actuator. Mark the gear tooth directly opposite of the alignment mark on the crankshaft sprocket.

  10. The timing chain has 30 links. Place links (1) and (30) on either side of the mark made on the camshaft position 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.

    GM5608839Courtesy of GENERAL MOTORS COMPANY
    NOTE:
    • Properly locate the camshaft position actuator (1) onto the locating pin of the camshaft (2).
    • The sprocket teeth and timing chain must mesh.
    • The camshaft and the crankshaft sprocket alignment marks MUST be aligned properly.
