Cylinder Head Assembly

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 (L11) 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.).

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.
