Tightening Sequence:
Cylinder Head Bolt Tightening Sequence:
Tighten the cylinder head bolts sequentially in two or three steps.
- Apply clean engine oil to the bolt threads and washer contact surfaces.
- In the final step tighten to 96 Nm (71 ft. lbs.)
NOTE: The manufacturer recommends using a beam-type torque wrench. When using a preset-type torque wrench, be sure to tighten slowly and not to over-tighten.
