INSTALLATION SERVICE POINTS

>>A<< INLET MANIFOLD/INJECTOR PROTECTOR FRONT INSTALLATION
1.Tighten the inlet manifold and the Injector protector temporarily, because they have the specified order.
2.When installing the fuel delivery pipe and fuel injector assembly, tighten the mounting bolts and nuts to the specified torque (Refer to GROUP 13C - Fuel Injector ).

>>B<< INLET MANIFOLD STAY INSTALLATION
1.Temporarily tighten the inlet manifold stay with mounting bolt.
2.Make sure that the inlet manifold stay is closely contacted with the installation surface of each part, and then tighten the mounting bolt to the specified torque.
Tightening torque: 20 ± 2 N·m

>>C<< O-RING/MANIFOLD ABSOLUTE PRESSURE SENSOR/PURGE CONTROL SOLENOID VALVE INSTALLATION
1.Apply a small amount of new engine oil to the O-ring.
2.Install the manifold absolute pressure sensor and the purge control solenoid valve to the inlet manifold with care not to damage the O-ring.
3.
caution Do not over-tighten. If the mounting screw is over-tightened, the inlet manifold can be damaged.
Tighten the mounting screws to the specified torque.
Tightening torque: 4.0 ± 1.0 N·m
