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

DEHYDRATION CANISTER-PRESSURE RELIEF
VALVE HIGH PRESSURE PIPE
REMOVAL
Detach the pipe from its mountings.
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.
REFITTING
Proceed in the reverse order to removal.
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.
NOTE:
- Pipe to dehydration canister
retaining bolt:0.8 daN.m
- Pipe to pressure relief valve
retaining nut:0.8 daN.m

• 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.
•0.28 Ω
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.
