TIGHTENING TORQUES
2-12
TIP
Cylinder head bolt
Tighten all the cylinder head bolts evenly in the tightening order to 30 N·m (3.0 kgf·m, 22 lb·ft). Remove
the one bolt according to the tightening order. When doing so, do not remove the other bolts. Retighten
the bolt to 15 N·m (1.5 kgf·m, 11 lb·ft), and then tighten it further to reach the specified angle (60
). Re-
move the remaining bolts one by one in the same manner and retighten them. Finally, tighten all the
bolts to reach the specified angle (60
). Total tightening angle: 60
+ 60
= 120
(The first and second
time, be sure to apply molybdenum disulfide oil to the bolt threads and seats as well as to both sides of
the lock washers.)
