Component Tightening Specifications and Sequences

Cylinder Head
Using several steps, uniformly install and tighten the 10 cylinder head set bolts and plate washers with a 10 mm bi-hexagon wrench in the order shown in the illustration.
Torque 70 Nm (714 kgf-cm, 52 ft. lbs.)





Mark the front of the cylinder head bolts with paint.
Retighten the cylinder head bolts by 90° as shown in the illustration.
Check that the paint mark is now at a 90° angle to the front.
Cylinder head set bolt
Standard bolt length 141.3 to 142.7 mm (5.563 to 5.618 inch)
Maximum bolt length 144.2 mm (5.677 inch)

CYLINDER HEAD FOR WARPAGE
Using a precision straightedge and feeler gauge, measure the warpage of the contact surfaces of the cylinder block and manifolds.
Maximum warpage 0.08 mm (0.0032 inch)
If the warpage is greater than the maximum, replace the cylinder head sub-assembly.





CYLINDER HEAD FOR CRACKS
Using a dye penetrant, inspect the combustion chamber, intake ports, exhaust ports and cylinder block surface for cracks.
If cracked, replace the cylinder head.
