  1. If removed, install the oil temperature sensor (1) and tighten to the proper specifications. Refer to TORQUE SPECIFICATIONS  .
  2. If removed, install the ignition coil capacitor, along with ground strap and tighten to the proper specifications. Refer to TORQUE SPECIFICATIONS  .
  3. Clean and prepare the gasket sealing surfaces of the cylinder head and block. Refer to ENGINE GASKET SURFACE PREPARATION  .
    CAUTION:

    Non-compressible debris such as oil, coolant or RTV sealants that are not removed from bolt holes can cause the aluminum casting to crack when tightening the bolts.

    CAUTION:

    When cleaning cylinder head and cylinder block surfaces, DO NOT use a metal scraper because the surfaces could be cut or ground. Use ONLY a wooden or plastic scraper.

  4. Clean out the cylinder head bolt holes in the engine block.
    WARNING:

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

    CAUTION:

    The installation of the cylinder head gaskets are not interchangeable between the left and right cylinder heads. They are clearly marked (3) with "R" for right and "L" for left. They must be applied on a dry surface, without the use of any adhesives.

  5. Position the new cylinder head gasket (1) on the locating dowels (2).

    CAUTION:

    The cylinder head bolts are tightened using a torque plus angle procedure. The bolts must be examined BEFORE reuse. If the threads are necked down the bolts must be replaced.

  6. Check cylinder head bolts for necking by holding a scale or straight edge against the threads. If all the threads do not contact the scale (2) the bolt must be replaced.
  7. Position the right cylinder head to the engine block, slightly forward in order to access the wire harness connectors.
  8. Connect the oil temperature sensor wire harness connector.
  9. Connect the ignition coil capacitor electrical connector.
  10. Position the cylinder head onto the cylinder block. Make sure the cylinder head seats fully over the locating dowels.
    NOTE:

    Do not apply any additional oil to the bolt threads.

  11. Install the eight cylinder head bolts finger tight.

  12. Tighten the cylinder head bolts in the sequence shown, following this 9 step torque plus angle method. The torque sequence must be used for each step. Tighten according to the following torque values:
    • Step 1: All to 30 N.m (22 ft. lbs.)
    • Step 2: All to 45 N.m (33 ft. lbs.)
    • Step 3: Re-tighten all to 45 N.m (33 ft. lbs.)
    • Step 4: All + 125° Turn (optional angle if 125° rotation cannot be accomplished in one motion; tighten all by turning 35° followed by tightening all by turning 90°) Do not use a torque wrench for this step. 
    • Step 5: Loosen all fasteners in reverse of sequence shown
    • Step 6: All to 30 N.m (22 ft. lbs.)
    • Step 7: All to 45 N.m (33 ft. lbs.)
    • Step 8: Re-tighten all to 45 N.m (33 ft. lbs.)
    • Step 9: All + 130° Turn (optional angle if 130° rotation cannot be accomplished in one motion; tighten all by turning 40° followed by tightening all by turning 90°) Do not use a torque wrench for this step. 
    NOTE:

    For engine builds using a new block follow steps 1-9. For engine re-builds (reuse block) follow step 6-9.

  13. Install the RH cam chain guide (1) with three bolts (2) and tighten the bolts (2) to the proper specifications. Refer to TORQUE SPECIFICATIONS  .
  14. Install the RH cam chain tensioner (3) to the engine block with two bolts (4) and tighten the bolts (4) to the proper specifications. Refer to TORQUE SPECIFICATIONS  .
  15. Reset the RH cam chain tensioner (3) by pushing back the tensioner piston and installing Tensioner Pin (special tool #8514A, Pins, Tensioner) (5).
  16. Install the RH tensioner arm (6).

  17. Drape the right side cam chain onto the idler sprocket (1) so that the dimple (2) is aligned with the plated link (3) on the cam chain.
    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.

  18. If removed, install the hydraulic lifters. Refer to LIFTER(S), HYDRAULIC, INSTALLATION .
    NOTE:

    If the rocker arms and hydraulic lifters are being reused, reassemble them into their original locations.

  19. Install the rocker arms and camshafts. Refer to CAMSHAFT, ENGINE, INSTALLATION .
    CAUTION:

    Do not rotate the camshafts more than a few degrees independently of the crankshaft. Valve to piston contact could occur resulting in possible valve damage. If the camshafts need to be rotated more than a few degrees, first move the pistons away from the cylinder heads by rotating the crankshaft counterclockwise to a position 30° before-top-dead-center. Once the camshafts are returned to their top-dead-center position, rotate the crankshaft clockwise to return the crankshaft to top-dead-center.

  20. Remove the Tensioner Pin (special tool #8514A, Pins, Tensioner) from the RH cam chain tensioner.

  21. Rotate the crankshaft clockwise two complete revolutions stopping when the dimple (7) on the crankshaft is aligned the with the block/bearing cap junction (6).
  22. Rotate the crankshaft clockwise to place the number one piston at Top Dead Center (TDC) on the exhaust stroke by aligning the dimple (7) on the crankshaft with the block/bearing cap junction (6). The left side cam phaser arrows (4) should point toward each other and be parallel to the valve cover sealing surface (3). The right side cam phaser arrows (5) should point away from each other and the scribe lines (1) should be parallel to the valve cover sealing surface (2).

  23. There should be 12 chain pins (2) between the exhaust cam phaser triangle marking (1) and the intake cam phaser circle marking (3).
  24. If the engine timing is not correct. Refer to INSTALLATION 
  25. Install the engine timing cover and cylinder head covers. Refer to INSTALLATION 
  26. Install the wire harness trough to the right cylinder head a secure the fasteners.
  27. Secure the wire harness trough to the left cylinder head.
  28. Install the spark plugs. Refer to 3.6L

  30. Install the oil level indicator (1).
  31. Install the right side catalytic converter to the cylinder head. Refer to 3.6L ENGINE
  32. Connect the right upstream oxygen sensor connectors to the main wire harness.
  33. Install the upper and lower intake manifolds. Refer to MANIFOLD, INTAKE, INSTALLATION 
  34. Install a new oil filter and fill the engine crankcase with the proper oil to the correct level. Refer to STANDARD PROCEDURE - ENGINE OIL AND FILTER CHANGE  .
  35. If equipped, install the skid plate. Refer to INSTALLATION
  36. Fill the cooling system. Refer to COOLANT SYSTEM AIR EVACUATION
  37. Connect the negative battery cable.
  38. Run the engine until it reaches normal operating temperature. Check cooling system for correct fluid level. Refer to COOLANT SYSTEM AIR EVACUATION
NOTE:

The Cam/Crank Variation Relearn procedure must be performed using the scan tool anytime there has been a repair/replacement made to a powertrain system, for example: flywheel, valvetrain, camshaft and/or crankshaft sensors or components.
