4.

Use special tool to tighten bolts according to the following
procedure (tightening for plastic zone).
(1) According to the sequence in the figure, tighten

bolts to the specified torque 74 

±

 2 N·m.

(2) In the reverse sequence of the figure, fully loosen

bolts.

(3) According to the sequence specified in the figure,

tighten bolts to the specified torque 20 

±

 2 N·m.

(4) Indicate paint markings on the heads of cylinder

head bolts and cylinder head, and tighten bolts at
the angle of 90 degrees in the sequence specified
in the figure.

(5) When bolts are tightened at the angle of 90

degrees according to the figure, ensure that the
paint markings on the heads of cylinder head
bolts and cylinder head are standing in line.

Caution
