Cylinder Head Assembly: Specifications

Cylinder Head
CYLINDER HEAD SUB-ASSEMBLY RH (for Bank 1)

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 N*m (367 kgf*cm, 27 ft.*lbf)
If any one of the cylinder head bolts does not meet the torque specification, replace the cylinder head bolt.

Step 2:
Mark the cylinder head bolt heads with paint as shown in the illustration.
Tighten the cylinder head bolts another 90° in the sequence shown in step 1.
Step 3:
Tighten the cylinder head bolts by an additional 90° in the sequence shown in step 1.
Check that the painted marks are now facing rearward.

CYLINDER HEAD SUB-ASSEMBLY LH (for Bank 2)

Install the 2 bolts in the order shown in the illustration.
Apply a light coat of engine oil to the threads of the cylinder head bolts.
Install the 2 cylinder head bolts. Using several steps, tighten the bolts uniformly in the sequence shown in the illustration.
Torque 30 N*m (306 kgf*cm, 22 ft.*lbf)

CYLINDER HEAD SET BOLT
Using a vernier caliper, measure the outside thread diameter of the bolt.
Measuring point 73.0 mm (2.87 in.)
Standard outside diameter 10.85 to 11.0 mm (0.427 to 0.433 in.)
Minimum outside diameter 10.7 mm (0.421 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.
