Main Bearing Cap Tightening Sequence
Install bearing caps and tighten cap bolts to the specified torque in the sequence of the center, No.2, No.4 front and rear caps. Cap bolts should be tightened evenly in 2 to 3 stages before they are tightened to the specified torque. The caps should be installed with the arrow mark directed toward the crank pulley side of engine. Cap numbers must be corrected.
Cylinder Head 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.
