Before reconnecting the AIR BAG

cushion it is necessary to apply the air bag system
operational check procedure :

• Check that the AIR BAG warning light on the

instrument panel is illuminated when the igni-
tion is switched on.

• Connect an inert ignition unit to the AIR BAG

cushion connector and check that the warning
light extinguishes.

• Switch off the ignition, connect the AIR BAG

cushion in place of the inert ignition unit and
secure the cushion on to the steering wheel.

• Switch on the ignition, check that the air bag

warning light illuminates for three seconds
when the ignition is switched on and then ex-
tinguishes and remains extinguished.

If the warning light does not operate as indicated
above, please consult section 88 of the workshop

equipment.

LOW PRESSURE PIPE

REMOVAL

Remove the mounting bolt on the pressure relief
valve.

Fit plugs to the pressure relief valve and the pipe.

Remove the mounting bolt on the compressor.

Fit plugs to the compressor and the pipe.

Unscrew the pipe retaining lug.

Remove the low pressure pipe.

REFITTING

Proceed in the reverse order to removal.

Check the condition of the seals and lubricate
them with

P.A.G. SP 10

oil.

When changing a pipe, add 10 ml of SP 10 oil or
when a pipe bursts (rapid leak), add 100 ml.

Create a vacuum, then fill the R134a coolant cir-
cuit using the filling equipment.

NOTE:

- Pipes to compressor

NOTE:

the front bumper must be removed on the

version fitted with the E7J engine, in order to re-
move the cut off (1) retaining bolt.

COMPRESSOR-CONDENSER HIGH PRESSURE PIPE

REMOVAL

Remove the mounting bolt on the compressor.

Fit plugs to the compressor and the pipe.

Remove the mounting bolt on the condenser.

Remove the pipe.

Fit plugs to the condenser and the pipe.

REFITTING

Proceed in the reverse order to removal.

NOTE:

When refitting this connecting pipe to the
compressor, it is essential to fit all the bolts and
then bring them into contact before torque tigh-
tening them. The aim is to ensure that the pipe is
positioned correctly so that it is not damaged at
the cut off (1).

Check the condition of the seals and lubricate
them using

P.A.G. SP 10

oil.

When changing a pipe, add 10 ml of SP 10 oil or
when a pipe bursts (rapid leak), add 100 ml.

Create a vacuum, then fill the R134a coolant cir-
cuit using the filling equipment.

Disconnect the pressure sensor connector.

Remove the mounting bolt on the pressure relief
valve.

Fit plugs to the pressure relief valve and the pipe.

Remove the mounting bolt on the dehydration ca-
nister.

Fit plugs to the dehydration canister and the pipe.

Remove the pipe.

• EVAPORATOR SENSOR (depending on assem-

bly)

REMOVAL

Disconnect the battery.

Remove:
- the windscreen wiper arms,
- the air inlet grille,
- the evaporator protector in the plenum cham-

ber.

Disconnect the evaporator sensor connector and
the air recirculation motor connector.

Free the wiring from its fasteners.

Remove the evaporator sensor.

REFITTING

Proceed in the reverse order to removal.

Ensure that the sensor is correctly positioned on
its seat on the evaporator.

FAN ASSEMBLY SPEED RESISTOR (2)

This is secured to the engine cooling fan support.

•

RECIRCULATION MOTOR

It is only possible to gain access to the recircula-
tion motor following removal of the air blower
unit (refer to the relevant section) and therefore
the evaporator assembly.

•

PRESSURE SENSOR

The pressure sensor (1) is located next to the
condenser on the pressure relief valve-
dehydration canister high pressure pipe.

All work on the pressure sensor can be carried out
without draining the coolant circuit. It is secured
to a "SKRADER" valve.

Tightening torque: 0.8 daN.m.

This pressure sensor is fitted with seal. Check that
it is in good condition on refitting and lubricate it
using

P.A.G. SP 10

oil.
