CYLINDER HEAD





Tighten the cylinder head bolts 1-8 in the sequence shown in. 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.

HEAD BOLT REUSE/REPLACE

The cylinder head bolts should be examined BEFORE reuse. If the threads are necked down, the bolts must be replaced.
