Cylinder Head Bolts
Clean the bolt threads and the bolt holes in the cylinder block
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.
Loosen all the bolts by 180° in the reverse order of installing, and 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" of steps does not exceed 90°.
Camshaft Cap bolts
Tightening torque:
T1: 9.75 Nm (1.0 kgf-m, 7.2 ft-lb)
T2: 20 Nm (2.0 kgf-m, 14.8 ft-lb)
After tightening the camshaft cap, ensure the camshaft rotates only slightly while holding it at base circle.
Camshaft Sprocket Bolt
Tightening torque:
Tighten to 30 Nm (3.1 kgf-m, 22.1 ft-lb)
Then Tighten further by 45°.
