Cylinder Head
Left Side
Important: DO NOT reuse the old M11 cylinder head bolts.
Step 1. Install new M11 cylinder head bolts in the cylinder head.
Step 2. Install the M6 cylinder head bolts at the front of the cylinder head.
Notice: Ensure the cylinder head bolts that are being used are the proper pitch or engine damage will occur. The thread pitch on the M11 cylinder head bolts and the engine block cylinder head bolt holes have been revised. In order to prevent engine damage it is important to identify which thread pitch is being used. Cylinder head bolts with a pitch of 1.5 mm have a thread length of about 48 mm (1.890 in) long. Cylinder head bolts with a pitch of 2.0 mm have a thread length of about 67 mm (2.638 in) long.
Step 3. Tighten the left cylinder head bolts in the sequence shown.
First Pass: Tighten the left cylinder head M11 cylinder head bolts to 30 N.m (22 lb ft)
Second Pass: Using the J 45059, tighten the left cylinder head M11 cylinder head bolts an additional 60 degrees
Third Pass: Repeat the sequence turning each bolt another 60 degrees
Final Pass: Repeat the sequence again turning each bolt a final 60 degrees, total 180 degrees
Step 4. Tighten the M6 bolts at the front of the cylinder head to 12 N.m (106 lb in)
