Disconnect the battery.
Drain the R134a coolant circuit using the filling
equipment.

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.

• 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.
