Cylinder head Bolts





Clean the bolt threads and the bolt holes in the cylinder block
Apply a sufficient coat of engine oil to the washer and bolt thread.

CAUTION
To avoid erroneous tightening of the bolts, clean out the bolt holes sufficiently by blowing with compressed air to eliminate engine coolant etc

Tighten all bolts to 40 Nm (4.1 kgf-m, 29.5 ft-lb) in alphabetical order.
Retighten all bolts to 95 Nm (9.7 kgf-m, 70.1 ft-lb) in alphabetical order.

CAUTION
If the bolt makes stick-slip sound during tightening, repeat the procedure from step 1. In this case, the cylinder head gasket can be reused.

Loosen all the bolts by 180° in the reverse order of installing
Loosen them further by 180°.
Tighten all bolts to 10 Nm (1.0 kgf-m, 7.4 ft-lb) in alphabetical order.
Retighten all bolts to 30 Nm (3.1 kgf-m, 22.1 ft-lb) in alphabetical order.
Retighten all bolts to 70 Nm (7.1 kgf-m, 51.6 ft-lb) in alphabetical order.
Retighten all bolts by 80 - 90° in alphabetical order.
Retighten all bolts by 40 - 45° in alphabetical order.

CAUTION
The tightening angle of the bolt should not exceed 45°

Retighten bolts (A) and (B) by 40 - 45°.

CAUTION
Make sure the total "tightening angle" does not exceed 90°
