INSTALLATION SERVICE POINTS

>>A<< INLET MANIFOLD/INJECTOR PROTECTOR FRONT INSTALLATION
Install the inlet manifold and the injector protector front, and tighten mounting bolts and nuts temporarily.
note The tightening of the fuel delivery pipe, the inlet manifold and the injector protector front and rear has the specified order. Temporarily tighten the inlet manifold and injector protector front mounting bolts and nuts (Refer to GROUP 13A - Injector ).

>>B<< INLET MANIFOLD STAY INSTALLATION
Make sure that the inlet manifold stay is in intimate contact with the inlet manifold and cylinder block boss before tightening it to the specified torque of 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
