System Specifications
INSPECT CYLINDER HEAD FOR FLATNESS
a. Using a precision straight edge and a feeler gauge, measure the surface contacting the cylinder block and the manifolds for warpage.
Maximum warpage:
Cylinder block side 0.05 mm (0.0020 inch)
Intake manifold side 0.10 mm (0.0039 inch)
Exhaust manifold side 0.10 mm (0.0039 inch)
If the warpage is greater than maximum, replace the cylinder head.
INSTALL CYLINDER HEAD SUB-ASSY
a. Place the cylinder head on the cylinder block.
b. Apply a light coat of engine oil on the threads and under the heads of the cylinder head bolts.
c. Using a bi-hexagon wrench 10, install and uniformly tighten the 10 cylinder head bolts with plate washers, in several passes, in the sequence shown.
Torque: 49 Nm (500 kgf-cm, 36 ft. lbs.)
d. Mark the front of the cylinder head bolt with paint.
e. Retighten the cylinder head bolts 90° in the numerical order shown.
f. Check that the point marked bolts are moved at 90° angle.
