Cylinder Head Assembly

Cylinder Head

The cylinder head bolts are tightened in 2 progressive steps.

Using several passes, uniformly install and tighten the 10 cylinder head set bolts and plate washers with a 10 mm bi-hexagon wrench in the order shown in the illustration.





Torque 49 Nm (500 kgf-cm, 36 ft-lbf)

Mark the front side of the cylinder head bolts with paint.





Further tighten the cylinder head bolts an additional 90°, then once more 45° as shown in the illustration.
Check that the paint mark is now at a 135° angle to the front.
