Cylinder Head

Cylinder Head





Tighten the cylinder head bolts in sequence to 39 Nm (4.0 kgf-cm, 29 ft. lbs.). When using a preset-type torque wrench, be sure to tighten slowly and do not overtighten. If a bolt makes any noise while you are torquing it, loosen the bolt and retighten it from the first step.





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°





Bolt Reusability:
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.
