    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.

  7. Check the 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.

    NOTE:

    Ensure cylinder head bolt holes in the block are clean, dry (free of residual oil or coolant), and threads are not damaged.

  8. Install the Variable Valve Actuation Assembly (VVAA) oil supply filter (1) in the engine block.

  9. Clean the cylinder head sealing surfaces with isopropyl alcohol in preparation for sealant application.
    CAUTION:

    Engine assembly requires the use of a unique sealant that is compatible with engine oil. Using a sealant other than Mopar® Engine Sealant RTV Silicone Rubber Adhesive may result in engine fluid leakage.

    CAUTION:

    Following the application of Mopar® Engine Sealant RTV Silicone Rubber Adhesive to the gasket surfaces, the components must be assembled within 10 minutes and the attaching fasteners must be tightened to specification within the next 10 minutes. Prolonged exposure to the air prior to assembly may result in engine fluid leakage.

  10. Place two pea size dots of Mopar® Engine Sealant RTV Silicone Rubber Adhesive (1) on the cylinder block as shown.

  13. Position the cylinder head onto the engine block.
    NOTE:

    Make sure the foam pad is not out of position. Inspect the positioning of the pad from below to make sure that no part of the pad is between the cylinder head and the engine block surface. 

  14. Lubricate the cylinder head bolt threads with clean engine oil and install all the cylinder head bolts finger tight.
  15. Tighten the cylinder head bolts in the sequence shown, following this 4 step torque plus angle method. Tighten according to the following torque values:
    • Step 1: All to 10 Nm (7 ft. lbs.)
    • Step 2: All to 16 Nm (12 ft. lbs.)
    • Step 3: All to 35 Nm (26 ft. lbs.)
    • Step 4: All an additional 160° ± 2° Do not use a torque wrench for this step.
