Thickness of 1.8 mm
The inhaling moment: 16 Н.м.

The prevention

When you remove the condenser in cars equipped 5цилиндровым the engine, first of all, unscrew a coolant line, the leader from the evaporator to the condenser.


Elements of management of the conditioner

1. The hatch of giving of fresh air and
recycling air
2. The external temperature gauge
3. The vacuum amplifier
It is intended for giving of fresh air in the hatch and for recycling air
4. An air inlet of the instrument panel
5. The bilateral valve
It is intended for giving of fresh air in the hatch and for recycling air
6. The delivery fan of fresh air
7. The panel of the central air inlet and a control system
8. The switch of giving of fresh air and a mode recycling
9. The switch of the air conditioner
10. The block of management of the conditioner
11. Ropes
Connection on the management block
Connections with folding заслонками
12. Apertures for heating of feet
13. Consecutive resistance of the delivery fan

The prevention

The devices described here, are located in a compartment of the engine and supplement elements of a central air of air.

For replacement of the faulty vacuum block it is necessary to remove a heater, first of all.


The scheme of an arrangement of components

1. The external temperature gauge
Removal and installation:
Uncover the ventilating hatch and a ware box
2. The hatch of giving of fresh air
3. The temperature gauge (on a cover)
4. The vacuum block of the managing director заслонки (having blown in feet and glasses)
Vacuum hoses
5. A connecting nest
For vacuum hoses and эпектрических heater contacts
6. An aperture for blowing feet
7. The vacuum block
Ensures functioning central air заслонки (заслонки regulating air receipt in apertures for blowing of feet and glasses)

8. The adjusting engine
Regulates position заслонки the temperature control (by means of a feedback potentiometer)
Feedback potentiometer
9. The vacuum block
Ensures functioning air заслонки retsirkulirouemogo/of fresh air
10. The engine of the fan forcing fresh air
11. A heater
Together with the evaporator
12. The management block
Regulates work of the delivery fan
13. The switch of low pressure
It is intended for maintenance of functioning of system of cooling
