c.Loosen all bolts completely.
d.Tighten all bolts to 39 N×m (4.0 kg-m, 29 ft-lb).
e.Method A:
Turn all bolts 90 to 95 degrees clockwise with Tool or
suitable angle wrench.
Method B:
If an angle wrench is not available, mark all cylinder head
bolts on the side facing engine front. Then, turn each cyl-
inder head bolt 90 to 95 degrees clockwise.
f.Turn all bolts another 90 to 95 degrees clockwise.
g.Ensure that paint mark on each bolt faces the rear of the
engine. (Method B only)
Do not turn any bolt 180 to 190 degrees clockwise all at once.
