Cylinder Head Torque/Sequence





Tighten cylinder head bolts.
a) Apply a coat of engine oil to washers and bolt threads.
b) Tighten all bolts to 29 Nm (3.0 kgf-m, 22 ft. lbs.) in alphabetical sequence.
Then tighten all bolts to 69 Nm (7.0 kgf-m, 51 ft. lbs.) in alphabetical sequence.
c) Back off all bolts by 180° first; back them off by 180° again.
d) Tighten bolts (a) and (b) to 34 Nm (3.5 kgf-m, 25 ft. lbs.).
e) Tighten bolts (c), (d), (e) and (f) to 15 Nm (1.5 kgf-m, 11 ft. lbs.).
f) Tighten all bolts by 80° to 90° in alphabetical sequence.

CAUTION: Do not tighten bolts more than 90°.


g) Further tighten all bolts by 80° to 90° in alphabetical sequence shown.

CAUTION: Ensure that the total "re-tightening angle" [in the former two steps], do not exceed 180°.
