SOURCE: Need Cylinder head bolt torque specs and sequence

  1. Install the cylinder head gasket. Ensure the arrows point towards the front of the engine. The left cylinder head gasket has the letter L stamped next to the arrow.
  2. Notice
  3. This bolt is designed to permanently stretch when tightened. The correct part number fastener must be used to replace this type of fastener. Do not use a bolt that is stronger in this application. If the correct bolt is not used, the parts will not be tightened correctly. The system or the components may be damaged.

  4. Install the cylinder head.
  5. Install new cylinder head bolts. Tighten
    Tighten the cylinder head bolts to 50 N·m (37 lb ft) in sequence.
  6. Use the J 36660-A to rotate each cylinder head bolt 120 degrees in sequence. Use the J 36660-A to rotate the four center cylinder head bolts an additional 30 degrees in sequence. Refer to Notice Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

What is the cylinder head torque 3.8l


First off, these bolts are designed to stretch when they are installed; so do not reuse the original bolts; always use new.
With that in mind, the first torque setting is 37ftlbs make sure to use the correct sequence always working from the center out, and one side across to the other. Once all the bolts are set to 37, go through and tighten to 120ftlbs using the same sequence center and across working your way out. 110312gif_00000002576.gif
