Cylinder Head

1. Tighten the cylinder head bolts 1 - 8 in the sequence shown. Using the 4 step torque turn method, tighten according to the following values:
- Step 1: Bolts 1 - 8 to 61 Nm (45 ft. lbs.)
- Step 2: Bolts 1 - 8 to 88 Nm (65 ft. lbs.)
- Step 3: Bolts 1 - 8 (again) to 88 Nm (65 ft. lbs.)
- Step 4: Bolts 1 - 8 turn an additional 1/4 Turn. Do not use a torque wrench for this step.

NOTE: Bolt torque after 1/4 turn should be over 122 Nm (90 ft. lbs.). If not, replace the bolt.

2. Tighten head bolt number 9 to 33 Nm (25 ft. lbs.) after head bolts 1 - 8 have been tighten to specifications.
