Step 3:

Mark each cylinder head bolt head with paint as shown in the illustration.






Tighten the cylinder head bolts 90° in the sequence shown in step 1.

Step 4:

Tighten the cylinder head bolts another 90° in the sequence shown in step 1.
Check that the paint marks are now facing rearward.

CYLINDER HEAD BOLT

Using a vernier caliper, measure the diameter of the threads at the measurement point.






Standard Diameter 10.85 to 11.00 mm (0.427 to 0.433 in.)

Minimum Diameter 10.6 mm (0.417 in.)

Measurement Point (Distance From The Seat) 106 mm (4.17 in.)

If the diameter is less than the minimum, replace the cylinder head bolt. Failure to do so may lead to engine damage.
If there is any thread deformation, replace the cylinder head bolt with a new one.
