Cylinder Head Assembly

CYLINDER HEAD SET BOLT





Using vernier calipers, measure the tension portion diameter of the bolt.
Standard outside diameter: 8.95 to 9.05 mm (0.3524 to 0.3563 in.)
Minimum outside diameter: 8.75 mm (0.3445 in.)
If the diameter is less than the minimum, replace the bolt.


CYLINDER HEAD LH

Maximum warpage
Cylinder block side: 0.05 mm (0.0020 in.)
Intake manifold side: 0.10 mm (0.0039 in.)
Exhaust manifold side: 0.10 mm (0.0039 in.)

NOTE: The cylinder head bolts are tightened in 2 successive steps.





Using several steps, install and tighten the 8 cylinder head bolts uniformly in the sequence shown in the illustration.
SST: 09011-38121
Torque: 54 Nm (550 kgf-cm, 40 ft-lbf)





Mark the front side of each cylinder head bolt head with paint as shown in the illustration.
Retighten the cylinder head bolts by 90° in the same sequence as step (c).
Check that each painted mark is now at 90° angle to the front.





Using a socket hexagon wrench 8 mm, install the hexagon bolt.
Torque: 19 Nm (189 kgf-cm, 14 ft-lbf)





Using several steps, install and tighten the 2 bolts and intake air connector bracket No.2 uniformly in the sequence shown in the illustration.
Torque: 7.0 Nm (71 kgf-cm, 62 in-lbf)
