    GC0144206Courtesy of CHRYSLER GROUP, LLC
    NOTE:

    The left side ignition coils are shown in illustration, the right side ignition coils are similar.

  35. Remove the ignition coils (2). Refer to COIL, IGNITION, REMOVAL .
    CAUTION:

    When aligning timing marks, always rotate engine by turning the crankshaft. Failure to do so will result in valve and/or piston damage.

    CAUTION:

    Always reinstall timing chains so that they maintain the same direction of rotation. Inverting a previously run chain on a previously run sprocket will result in excessive wear to both the chain and sprocket.

    Fig 16: Rotating Crankshaft Clockwise To Position No. 1 Piston At TDC On Exhaust Stroke
    GC0144142Courtesy of CHRYSLER GROUP, LLC
  36. Rotate the crankshaft clockwise to place the number one piston at TDC on the exhaust stroke by aligning the dimple (4) on the crankshaft with the block/bearing cap junction (5). The left side cam phaser arrows (2) should point toward each other and be parallel to the valve cover sealing surface (3). The right side cam phaser arrows (7) should point away from each other and the scribe lines (9) should be parallel to the valve cover sealing surface (8).
  37. Mark the direction of rotation on the timing chain using a paint pen or equivalent to aid in reassembly.
    CAUTION:

    When the timing chains are removed and the cylinder heads are still installed, DO NOT rotate the camshafts or crankshaft without first locating the proper crankshaft position. Failure to do so will result in valve and/or piston damage.

    NOTE:

    If the rocker arms are to be reused, identify their positions so that they can be reassembled into their original locations.

  48. Remove the rocker arms. Refer to ROCKER ARM, VALVE, REMOVAL .
    NOTE:

    If the hydraulic lifters are to be reused, identify their positions so that they can be reassembled into their original locations.

  49. If required, remove the hydraulic lifters. Refer to LIFTER(S), HYDRAULIC, REMOVAL .
  50. Using the sequence shown in illustration, remove the cylinder head retaining bolts.
    WARNING:

    The multi-layered steel head gaskets have very sharp edges that could cause personal injury if not handled carefully.

    CAUTION:

    Do not lay the cylinder head on its gasket sealing surface, due to the design of the cylinder head gasket, any distortion to the cylinder head sealing surface may prevent the gasket from properly sealing resulting in leaks.
