TIGHTENING PROCEDURES
Intake Manifold





^ Loosen in reverse order shown in the figure.
^ Tighten in numerical order shown in the figure.
1. Tighten all bolts and nuts to 4.9 to 9.8 Nm (0.50 to 0.99 kg-m, 4 to 7 ft. lbs.).
2. Finally tighten all bolts and nuts to 26.5 to 31.4 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 three 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, 6.9 to 7.9 ft. lbs.).
2. Then tighten all bolts to 20.6 to 26.5 Nm (2.1 to 2.7 kg-m, 16 to 19 ft. lbs.).

Fuel Damper





Tighten fuel damper 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 damper tightened at the specified torque.
^ Always replace O-ring with new ones.
^ Lubricate O-ring with new engine oil.

Electronic Control Throttle Actuator





^ Tighten in numerical order shown in the figure.
Tighten all bolts to 7.2 to 9.6 Nm (0.74 to 0.97 kg-m, 64 to 84 inch lbs.).

CAUTION:
^ Perform "Throttle Valve Closed Position Learning" when harness connector of electronic throttle control actuator is disconnected.
^ Perform "Idle Air Volume Learning" when electronic throttle control actuator is replaced.

Intake Manifold Upper Collector

Intake Manifold Upper Collector / Torque Sequence:

^ Loosen in reverse order and tighten in numerical order shown in the figure.
Tighten all bolts to 17.6 to 21.6 Nm (1.8 to 2.2 kg-m, 13 to 15 ft. lbs.).

Intake Manifold Lower Collector

Intake Manifold Lower Collector / Torque Sequence:

^ Loosen in reverse order shown in the figure.
^ Tighten in numerical order shown in the figure.
Tighten bolts and nuts to 17.6 to 21.6 Nm (1.8 to 2.2 kg-m, 13 to 15 ft. lbs.).

Power Valve





^ Tighten in numerical order shown in the figure.
Tighten all bolts to 17.6 to 21.6 Nm (1.8 to 2.2 kg-m, 13 to 15 ft. lbs.).

Exhaust Manifold








^ Loosen in reverse order shown in the figure.
^ Tighten in numerical order shown in the figure.
Tighten nuts to 28.4 to 33.3 Nm (2.9 to 3.3 kg-m, 21 to 24 ft. lbs.).
