Tighten all cylinder head bolts.
Tightening Torque 34.3 - 44.1 Nm (3.5 - 4.4 kg-m, 26 - 32 ft. lbs.)





Turn all bolts 90 to 95 degrees clockwise [target: 90 degrees (angle tightening)].

CAUTION: Check the tightening angle by using angle wrench [SST]. Avoid judgment by visual inspection without tool.

Check tightening angle indicated on angle wrench [SST] indicator plate.
Turn all bolts 90 to 95 degrees clockwise again [target: 90 degrees (angle tightening)].
