Cylinder Head Torque and Sequence
HINT:
The cylinder head bolts are tightened in 2 progressive steps.
If any cylinder head bolt is broken or deformed, replace it.
Apply a light coat of engine oil to the threads and under the heads of the cylinder head bolts.
Install and uniformly tighten the 10 cylinder head bolts, and plate washers, in the order shown in the illustration.
Torque 40 Nm (408 kgf-cm, 30 ft. lbs.)Initial Torque + 90° + 90°
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 order shown.
Retighten the cylinder head bolts by an additional 90°.
Check that the painted mark is now at a 180° angle to front.
