Cylinder HeadCYLINDER HEAD SUB-ASSEMBLY
Place the 2 cylinder heads in position on the cylinder head gaskets.
Install the cylinder head bolts.
HINT:
The cylinder head bolts are tightened in 3 progressive steps (Procedures "A" and "B").
If any cylinder head bolt is broken or deformed, replace it.
Install the plate washer to the cylinder head bolt.
Install and uniformly tighten the 10 cylinder head bolts on one side of the cylinder head in several steps in the order shown in the illustration, then do the other side in the same way (Procedure "A").
Torque 40 Nm (408 kgf/cm, 30 ft. lbs.)
If any one of the cylinder head bolts does not meet the torque specification, replace the cylinder head bolt.
NOTICE: Do not drop the plate washer for the cylinder head bolt into portion A of the cylinder head. If dropped into portion A, the plate washer will pass through the cylinder head and cylinder block into the oil pan.
Mark the front of the cylinder head bolt head with paint.
Retighten the cylinder head bolts by 90° in the numerical order shown (Procedure "B").
Retighten the cylinder head bolts by an additional 90°.
Check that the painted mark is now at a 180° angle to front.
CYLINDER HEAD SET BOLT
Using vernier calipers, measure the thread outside diameter of the bolt.
Standard outside diameter 9.810 to 9.960 mm (0.3862 to 0.3921 in.)
Minimum outside diameter 9.700 mm (0.3819 in.)
Inspect for warpage.
Using a precision straight edge and feeler gauge, measure the warpage of the contact surfaces of the cylinder block and the manifolds.
Maximum warpage 0.10 mm (0.0039 in.)
If warpage is greater than the maximum, replace the cylinder head.
Inspect for cracks.
Using a dye penetrant, check the combustion chamber, intake ports, exhaust ports and cylinder block surface for cracks.
If cracked, replace the cylinder head.
