REMOVAL AND INSTALLATIONTIGHTENING PROCEDURES
Intake Manifold
Intake Manifold Torque Sequence:
- Tighten in numerical order shown in the figure.
1. Tighten all bolts and nuts to 5 to 10 Nm (0.5 to 1.0 kg-m, 44 to 86 inch lbs.).
2. Finally tighten all bolts and nuts to 26 to 31 Nm (2.7 to 3.2 kg-m, 20 to 23 ft. lbs.).
- Tighten all bolts and nuts to the final torque, evenly dividing the tightening into at least five steps.
Fuel Tube
- Tighten in numerical order shown in the figure.
1. Tighten all bolts to 9.3 to 10.8 Nm (0.95 to 1.1 kg-m, 83 to 95 inch lbs.).
2. Then tighten all bolts to 21 to 26 Nm (2.1 to 2.7 kg-m, 15 to 20 ft. lbs.).
Fuel Pressure Regulator
Tighten fuel pressure regulator to 2.9 to 3.8 Nm (0.3 to 0.39 kg-m, 26.0 to 33.9 inch lbs.).
- Tighten screws evenly several times to have the fuel pressure regulator tightened at the specified torque.
- Always replace 0-ring with new ones.
- Lubricate 0-ring with new engine oil.
Throttle Body
- Tighten in numerical order shown in the figure.
1. Tighten all bolts to 8.8 to 10.8 Nm (0.9 to 1.1 kg-m, 79 to 95 inch lbs.).
2. Then tighten all bolts to 17.7 to 21.6 Nm (1.8 to 2.2 kg-m, 13 to 16 ft. lbs.).
Intake Manifold Collector
Tighten bolts and nuts to 11 to 15 Nm (1.1 to 1.6 kg-m, 8 to 11 ft. lbs.) in numerical order shown in the figure.
