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) or equivalent. Repeat the procedure, re-tightening all cylinder head bolt to the specified torque.
Cylinder head bolt
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 and repeat it one more time as shown in illustration.

4. Install the timing belt tensioner pulley.
5. Install the timing belt on the camshaft sprocket, making sure that the tension side is tightened by turning the camshaft sprocket in reverse, all timing marks are in alignment.
6. Adjust the timing, refer to Timing Components.
7. Install the rocker cover and tighten the bolts to 8-10 Nm (80-100 kg. Cm, 5.8-7.2 ft. Lbs.).
8. Install the timing belt cover.
9. Install the new intake manifold gasket and the intake manifold, tighten the nuts and bolts to 15-20 Nm (150-200 kg. Cm, 11-14 ft. Lbs.).
10. Install the new exhaust manifold gasket and the exhaust manifold, tighten the nuts and bolts to 15-20 Nm (150-200 kg. Cm, 11-14 ft. Lbs.).
11. Install the surge tank and tighten the nuts bolts to 15-20 Nm (150-200 kg. Cm, 11-14 ft. Lbs.).

Good morning,

I attached a chart for the torque for you to view.

Using the sequence shown in the illustration and a cylinder head bolt wrench tool No. 09221-11000, or equivalent, tighten all cylinder head bolts in two steps using the following specifications:
M10: 30 Nm (22 ft lb) + (60 +65 ) + (60 +65 )
M12: 35 Nm (26 ft lb) + (60 +65 ) + (60 +65 )
