Cylinder Head Assembly
CYLINDER HEAD SUB-ASSEMBLYThe cylinder head bolts are tightened in 3 progressive steps.
Apply a light coat of engine oil to the threads and under the heads of the cylinder head bolts.
Step 1:
Using a 10 mm bi-hexagon wrench, install and uniformly tighten the 8 cylinder head bolts with the plate washers in several steps in the sequence shown in the illustration.
Torque 36 Nm (367 kgf-cm, 27 ft-lbf)
Step 2:
Mark the front side of each cylinder head bolt head with paint.
Tighten the cylinder head bolts another 90°.
Step 3:
Tighten the cylinder head bolts an additional 90°.
Check that the paint mark is now at a 180° angle to the front.
