SURFACE VARIATIONCylinder Head For Out-of-flatness 0.0508 mm (0.002 in.)
CYLINDER HEAD
Tighten the bolts in sequence using the following steps and torque values:
Tighten the bolts 1 through10 to 27 Nm (20 ft. lbs.)
Tighten the bolts 1 through 10 to 27 Nm (20 ft. lbs.) again.
Tighten bolts 11 through- 14 to 14 Nm (89 in. lbs.)
Rotate bolts 1 through10 an additional 90°.
Rotate bolts 1 through 10 an additional 90° again.
Tighten bolts 11 through 14 to 26 Nm (19 ft. lbs.)
HEAD BOLT REUSE/REPLACE
The cylinder head bolts are tightened using a torque plus angle procedure. The bolts must be examined BEFORE reuse. If the threads are necked down the bolts should be replaced.
