Cylinder Head Bolt Torque and Sequence

Tightening Sequence:

Install the cylinder head bolts. Starting at top center, tighten all cylinder head bolts in sequence as shown in illustration, using the Cylinder Head Bolt Wrench(09221-11001). Repeat the procedure, retightening all cylinder head bolts to the specified torque.

Cylinder Head Bolt Tightening torque:
M10: 30 Nm (300 kg.cm, 22 ft. lbs.) + (60° - 65°) + (60° - 65°)
M12: 35 Nm (350 kg.cm, 26 ft. lbs.) + (60° - 65°) + (60° - 65°)

NOTE: When tightening the cylinder head bolt, using special tool and torque wrench, tighten the bolt to the specified torque [M10: 30 Nm, M12: 35 Nm] and then turn the torque wrench 60° - 65° in sequence, then another 60° - 65° in sequence, as shown in illustration.
