REMOVAL SERVICE POINT

<<A>> POWER STEERING OIL PUMP ASSEMBLY REMOVAL
1.With the hose installed, remove the power steering oil pump assembly from the bracket.
2.Tie the removed power steering oil pump assembly with a string at a position where it will not interfere with the removal and installation of the inlet manifold.

INSTALLATION SERVICE POINTS

>>A<< SCREW INSTALLATION
caution Do not over-tighten. As the self-forming-type screw is used, the excessive torque can damage the inlet manifold threads.

>>B<< MANIFOLD ABSOLUTE PRESSURE SENSOR INSTALLATION
caution
  • Install the manifold absolute pressure sensor, taking care not to give a shock to it.
  • Do not use a manifold absolute pressure sensor that has fallen down.

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