CYLINDER HEAD

HINT: The cylinder head bolts are tightened in 2 successive steps.

Apply a light coat of engine oil to the threads of the cylinder head bolts.





Using several steps, install and tighten the 10 cylinder head bolts and plate washers uniformly with an 8 mm bi-hexagon wrench in the sequence shown in the illustration.

Retighten the cylinder head bolts by an additional 90° and then another 90°, as shown in the illustration.

Check that the paint mark is now 180° opposite to the front.
