Torque Specifications

Tighten cylinder head bolts in numerical order using angle wrench [ST10120000 (J24239-01)].

Apply engine oil to threads and seating surfaces of cylinder head bolts before installing them.
Cylinder head bolts for 4, 7, 9 and 12 are longer than the others.

L-1: 127 mm (5.00 inch) for 4, 7, 9 and 12
L-2: 106 mm (4.17 inch) for others

Install intake manifold and cylinder head at the same time using the following procedure:

1. Tighten cylinder head bolts to 29 Nm (3.0 kg-m, 22 ft. lbs.).
2. Tighten cylinder head bolts to 59 Nm (6.0 kg-m, 43 ft. lbs.).
3. Loosen cylinder head bolts completely.
4. Tighten cylinder head bolts to 10 Nm (1.0 kg-m, 7 ft. lbs.).
5. Tighten intake manifold bolts and nuts to 4 Nm (0.4 kg-m, 2.9 ft. lbs.)
6. Tighten intake manifold bolts and nuts to 18 Nm (1.8 kg-m, 13 ft. lbs.)
7. Tighten intake manifold bolts and nuts to 16 to 20 Nm (1.6 to 2.0 kg-m, 12 to 14 ft. lbs.).
8. Loosen intake manifold bolts and nuts completely.
9. Tighten cylinder head bolts to 29 Nm (3.0 kg-m, 2.2 ft. lbs.).






Turn cylinder head bolts to 60 to 65 degrees clockwise. If an angle wrench is not available, tighten cylinder head bolts to 54 to 64 Nm (5.5 to 6.5 kg-m, 40 to 47 ft. lbs.).
Tighten cylinder head sub-bolts to 9.0 to 11.8 Nm (0.92 to 1.20 kg-m, 6.7 to 8.7 ft. lbs.).
Tighten intake manifold bolts and nuts to 4 Nm (0.4 kg-m, 2.9 ft. lbs.).
Tighten intake manifold bolts and nuts to 9 Nm (0.9 kg-m, 6.5 ft. lbs.).
Tighten intake manifold bolts and nuts to 8 to 10 Nm (0.8 to 1.0 kg-m, 5.8 to 7 ft. lbs.).


















Install crankshaft and main bearing caps and tighten bolts to 90-100 Nm (9.2-10.2 kg-m, 67-74 ft.lb)
Prior to tightening bearing cap bolts, place bearing cap in its proper position by shifting crankshaft in the axial direction.
Tighten bearing cap bolts gradually in two or three stages. Start with center bearing and move outward sequentially.
After securing bearing cap bolts, make sure crankshaft turns smoothly by hand.


Connecting rod bearing nut
1. Tighten to 14 to 16 Nm (11.4 to 1.6 kg-m, 10 to 12 ft. lbs.).
2. Turn nuts 60 to 65 degrees clockwise. If an angle wrench is not available, tighten nuts to 38 to 44 Nm (3.9 to 4.5 kg-m, 28 to 33 ft. lbs.).
