Torque Specifications

Cylinder Head Bolts




Measure the diameter of each cylinder head bolt at point A and point B.
If either diameter is less than 10.6 mm (0.42 inch), replace the cylinder head bolt.




Tighten the cylinder head bolts in sequence to 39 Nm (4.0 kgf-cm, 29 ft. lbs.).




After torquing, tighten all cylinder head bolts in two steps (90° per step).
If you are using a new cylinder head bolt, tighten the bolt an extra 90°.


Intake Manifold




Tighten all intake manifold mounting bolts/nuts in a crisscross pattern in two or three steps, beginning with the inner bolt.


Rocker Arm Assembly Torque and Sequence




Tighten the bolts to the specified torque.
Specified torque:
8 mm bolts: 22 Nm (2.2 kgf-cm, 16 ft. lbs.)
6 mm bolts: 12 Nm (1.2 kgf-cm, 8.7 ft. lbs.)
6mm bolts: (21), (22), (23)


Exhaust Manifold and Shield




Tighten the bolts/nuts in a crisscross pattern in two or three steps, beginning with the inner bolt.
