Cylinder Head Bolt Torque and Sequence

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.
Torque 29 Nm (300 kgf-cm, 22 ft. lbs.)





Mark the front of the cylinder head bolts with paint.
Using the same sequence as step (c), retighten the cylinder head bolts by additional 90° and one more additional 90° as shown in the illustration.
Check that each paint mark is now at 180° opposite to the front.
