CAUTION:

The magnetic timing wheels (1) must not come in contact with magnets (pickup tools, trays, etc.) or any other strong magnetic field. This will destroy the timing wheels ability to correctly relay camshaft position to the camshaft position sensor.



    1. If removed, install the Engine Coolant Temperature (ECT) sensor (2) and tighten to the proper 

       
    1. If removed, install the ignition coil capacitor and the engine wire harness retainer bracket and tighten to the proper 

      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.



      NOTE:

      Typical cylinder head bolt shown.

       
    1. Check cylinder head bolts for necking by holding a scale or straight edge against the threads. If all of the threads do not contact the scale (2) the bolt must be replaced.


      NOTE:

      Right head gasket shown, left head gasket similar.

      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.

       
    1. Clean and prepare the gasket sealing surfaces of the cylinder head and block 

      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.

       
    1. 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.

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

       
    1. Using care, position the cylinder head onto the engine block.

      NOTE:

      Do not apply any oil to the bolt threads.

       
    1. Install the eight head bolts finger tight.

       
    1. 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.



      NOTE:

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

       
    1. If removed, install the hydraulic lifters 

      NOTE:

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

      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.

Position the cam phasers so that the arrows (4) point toward each other and are parallel to the valve cover sealing surface. Press the exhaust cam phaser onto the exhaust cam, install and hand tighten the oil control valve.
