^ Tools Required
- J 28410 Gasket Remover
- J 45059 Angle Meter

Removal Procedure





1. Remove the following subassemblies:
^ The left exhaust manifold.
^ The generator.
^ The water crossover.
^ The intake manifold.
^ The camshaft cover.
^ The engine front cover.
^ The left secondary camshaft drive chain.
2. Remove the power steering return hose retaining bolt from the cylinder head.





3. Remove the 3 M6 external drive bolts from the front portion of the cylinder head.

Important: DO NOT reuse the M11 cylinder head bolts.

4. Remove and discard the ten M11 internal drive cylinder head bolts.





5. Remove the left cylinder head. Make sure that no dowel guide pins are stuck in the cylinder head.

Important: You must clean the thread sealant material from the cylinder head bolt holes in the cylinder block. Failure to do so could cause false torque readings during reassembly.

6. After removing the cylinder head, remove any remaining bolt thread sealant material from the threaded cylinder block holes.

Important: DO NOT reuse the cylinder head gasket.





7. Remove the left cylinder head gasket.
8. Remove all remaining gasket material from the cylinder head and cylinder block using the J 28410.
9. Place the cylinder head on a flat, clean surface with the combustion chambers face-up in order to prevent damage to the deck face.
10. Clean and inspect the cylinder head.

Installation Procedure





1. Make sure all the cylinder head locating pins are securely mounted in the cylinder block deck face.

Important: Failure to remove all the old thread sealant material from the cylinder block could cause false torque readings.

2. Make sure any old thread sealant material is removed from the cylinder head bolt holes in the cylinder block.





3. Install a new left cylinder head gasket using the deck face locating pins for retention.





4. Align the cylinder head with the deck face locating pins.
5. Place the cylinder head in position on the deck face.

Important: DO NOT reuse the old M11 cylinder head bolts.





6. Install new M11 cylinder head bolts in the cylinder head.
7. Install the M6 cylinder head bolts at the front of the cylinder head.

Notice: Refer to Fastener Notice in Service Precautions.
