Cylinder Head Cover
Cylinder Head Cover:
Tighten cylinder head bolts in numerical order using angle wrench [ST10120000 (324239-01)].
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 (L1) than the others.
L1: 127 mm (5.00 inch) for 4, 7, 9 and 12
L2: 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, 22 ft. lbs.).
10. 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.).
11. 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.).
12. Tighten intake manifold bolts and nuts to
4 Nm (0.4 kg-m, 2.9 ft. lbs.).
13. Tighten intake manifold bolts and nuts to
9 Nm (0.9 kg-m, 6.5 ft. lbs.).
14. Tighten intake manifold bolts and nuts to
8 to 10 Nm (0.8 to 1.0 kg-m, 5.8 to 7 ft. lbs.).
Intake Manifold Installation Sequence:
If only intake manifold is removed and to be used again, install it using the following procedure:
1. Tighten all bolts and nuts to
4 Nm (0.4 kg-m, 2.9 ft. lbs.).
2. Tighten all bolts and nuts to
9 Nm (0.9 kg-m, 6.5 ft. lbs.).
3. Tighten all bolts and nuts to
8 to 10 Nm (0.8 to 1.0 kg-m, 5.8 to 7 ft. lbs.).
CAUTION: If replacing intake manifold with a new one, cylinder head gasket must also be replaced with a new one.
