Tightening Torque & Sequence

TORQUE









CYLINDER HEAD






Tighten the cylinder head bolts in the sequence shown using the following four step torque-turn method:
Step 1: All 61 Nm (45 ft. lbs.)
Step 2: All 88 Nm (65 ft. lbs.)
Step 3: All (again) 88 Nm (65 ft. lbs.)
Step 4: + 90° Turn

CAUTION: Do not use a torque wrench for this step.

Bolt torque after 90° turn should be over 122 Nm (90 ft. lbs.) in the tightening direction. If not, replace the bolt.

HEAD BOLT REUSE/REPLACE










The cylinder head bolts must be examined BEFORE reuse. If the threads are necked down the bolts must be replaced. Failure to replace a damaged bolt may lead to possible engine damage.
