Component Tightening Specifications and Sequences
Cylinder HeadBank 1
Install the 8 cylinder head bolts.
HINT:
The cylinder head bolts are tightened in 2 successive steps (steps (3) and (5)).
If any cylinder head bolts are broken or deformed, replace them.
Using several steps, tighten each bolt uniformly with a 10 mm bi-hexagon wrench in the sequence shown in the illustration.
Torque 36 Nm (367 kgf-cm, 27 ft. lbs.)
If any cylinder head bolts do not meet the torque specification, replace them.
NOTICE: Do not drop the washers into the cylinder head.
Mark the front side of each cylinder head bolt with paint.
Retighten the cylinder head bolts 180° as shown.
Check that the painted marks are now at 180° from the engine front.
