Cylinder Head Assembly

INSPECT CYLINDER HEAD SET BOLT

(a) Using a vernier caliper, measure the minimum diameter of the elongated thread at the measuring point.





Standard outside diameter:

10.85 to 11.00 mm (0.4272 to 0.4331 in.)

Minimum outside diameter:

10.70 mm (0.4213 in.)

Measuring point:

103 mm (4.06 in.)

HINT
* If a visual check reveals no excessively thin areas, check the center of the bolt (see illustration) and find the area that has the lowest diameter.
* If the diameter is less than the minimum, replace the cylinder head bolt.

CYLINDER HEAD SUB-ASSEMBLY RH

The 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 and in the sequence shown in the illustration.

Step 2






Mark the cylinder head bolt head with paint as shown in the illustration.
Tighten the cylinder head bolts another 90°.

Step 3

Tighten the cylinder head bolts by an additional 90°.
Check that the painted mark is now facing rearward.
