Installation Procedure
Notice: Refer to Engine Emission Notice in Service Precautions.
1. Install the valves, the springs, the seals and the caps to the cylinder head.
Notice: Head gaskets are not interchangeable. The head gasket must be installed with the arrow pointing to the front of the engine. Installing the head gasket in any other direction will cause gasket failure and possible engine failure.
2. Position the head gasket with the arrow pointing to the front of the engine.
3. Install the cylinder head.
Notice: 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.
Notice: This engine uses special torque to yield head bolts. This design bolt requires a special tightening procedure. Failure to follow the given procedure will cause head gasket failure and possible engine damage.
Notice: Refer to Fastener Notice in Service Precautions.
4. Install the new cylinder head bolts (1-8).
- Tighten the cylinder head bolts (1-8) in sequence to 50 Nm (37 ft. lbs.).
- Rotate each cylinder head bolt (1-8) 120 degrees in sequence. Use the J 36660-A.
- Rotate the center four cylinder head bolts (1-4) an additional 30 degrees. Use the J 36660-A.
