CAUTION:
Use new cylinder head gaskets.
2) Tighten cylinder head bolts.
(1) Apply a coat of engine oil to washers and
bolt threads.
(2) Tighten all bolts to 29 N·m (3.0 kg-m, 22
ft-lb) in alphabetical sequence.
Then tighten all bolts to 69 N·m (7.0 kg-m, 51
ft-lb) in alphabetical sequence.
(3) Back off all bolts by 180° first; back them off
by 180° again.
(4) Tighten bolts (a) and (b) to 34 N·m (3.5
kg-m, 25 ft-lb).
(5) Tighten bolts (c), (d), (e) and (f) to 15 N·m
(1.5 kg-m, 11 ft-lb).
(6) Tighten all bolts by 80 to 90° in alphabetical
sequence.
CAUTION:
Do not tighten bolts more than 90°.
(7) Further tighten all bolts by 80 to 90° in
alphabetical sequence shown in figure below.
CAUTION:
Ensure that the total “re-tightening angle” [in
the former two steps], do not exceed 180°.
