TORQUE SPECIFICATIONS
The cylinder head bolts are tightened in sequence in two steps:
Step 1: 129-142 Nm (95-105 ft. lbs.).
Step 2: 143-151 Nm (105-112 ft. lbs.).

When cylinder head bolts have been tightened following this procedure, it is not necessary to retighten the bolts after extended operation. However, the bolts can be checked and retightened if desired.
