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 10 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. Refer to Cylinder Head Cleaning and Inspection .

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 the Preface section.




8. Tighten the left cylinder head bolts in the sequence shown.

Tighten

1. Tighten the left cylinder head M11 cylinder head bolts to 40 N·m (30 lb ft) in the sequence shown.
2. Using the J 45059 , tighten the left cylinder head M11 cylinder head bolts an additional 70 degrees in the sequence shown.
3. Repeat the sequence turning each bolt another 60 degrees.
4. Repeat the sequence again turning each bolt a final 45 degrees (total 175 degrees).
9. Tighten the M6 bolts at the front of the cylinder head.

Tighten
