Torque Head Bolts
NOTE: Cylinder head bolts are allowed to be reused and torqued only three (3)
times. Discard these bolts after the third torque because they lose their elasticity and
strength and should not be torqued for a fourth time. Remove cylinder head covers.

Tightening Process is as follows:
a. After lubricating bolt and thread part, tighten the bolts to 30N·m; follow the order in
Illustration 14.
