Intake Manifold (W/ Glow Plug Controller) -- Inspection



1. INSPECT INTAKE MANIFOLD

NOTICE:
Hilux. Tgn26, 36 Kun25, 26, 35, 36 Ggn25
Do not adjust the adjusting screw or 2 swirl control valve actuator installation bolts.


  1. Check the operation of the swirl control valve.

    1. Check that the valve is fully opened under normal conditions.

    2. for DPF:
      Connect a vacuum pump to the control valve. Check that the valve is fully closed when a negative pressure of 35 kPa (263 mmHg, 10 in.Hg) is applied.



    3. for i-ART:
      Connect the vacuum pumps as shown in the illustration. First apply negative pressure to the diaphragm closer to the intake manifold. This will cause the actuator rod to move, which causes the swirl control valve to move. Then, apply negative pressure to the diaphragm on the outer side. This will cause the actuator rod to move further, which also causes the swirl control valve to move further. Check that the valve is fully closed when a negative pressure of 35 kPa (270 mmHg, 10 in.Hg) is applied.

      HINT:
      When applying negative pressure to the diaphragm on the outer side, the diaphragm closer to the intake manifold must be in a vacuum state.

    4. Leave it for 1 minute and check that the vacuum pump needle does not move. If the result is not as specified, replace the intake manifold.
