Cylinder Head Assembly

NOTE: New cylinder head bolts must be installed. They are torque-to-yield designed and cannot be reused.





Position the LH cylinder head and gasket and install the bolts. Tighten the bolts in six stages, in the sequence shown:

Stage 1: Tighten to 40 Nm (30 ft. lbs.).
Stage 2: Tighten bolts 90 degrees.
Stage 3: Loosen one full turn.
Stage 4: Tighten to 40 Nm (30 ft. lbs.).
Stage 5: Tighten 90 degrees.
Stage 6: Tighten 90 degrees.

Cylinder Head Flatness

NOTE: The straightedge used must be flat within 0.0051 mm (0.0002 inch) per foot of tool length.

Support the cylinder head on a bench with the head gasket side up. Inspect all areas of the deck face with a straightedge and feeler gauge. The cylinder head must not have depressions deeper than 0.0254 mm (0.001 inch) across a 38.1 mm (1.5 inch) square area, or scratches more than 0.0254 mm (0.001 inch) deep.
