Move aside the dashboard by removing:
- the six steering column mounting bolts,
- the four dashboard side retaining nuts and the
two bolts behind the ashtray assembly.
NOTE: take care to protect the sections of the
dashboard which are susceptible to damage using
cloths.
Remove the two evaporator housing mountings
behind the dashboard on the passenger side.
Remove the evaporator housing.
Carefully remove the evaporator from its housing.
REFITTING
Check that the harness tubes are not in contact
(risk of noise).
Proceed in the reverse order to removal.
Tighten the retaining nut (connecting pipes to
pressure relief valve) to 0.8 daN.m (pay attention
to the condition of the seals).
NOTE: when refitting the dashboard, check:
- that the electrical wiring is positioned correctly,
- that the air flow pipes are positioned correctly
(glove box for example).
Create a vacuum, then fill the R134a coolant cir-
cuit using the filling equipment.
IMPORTANT
When an evaporator is changed, add 30 ml of
P.A.G. SP 10 oil to the circuit.
Use the same oil for refitting the seals taking care
to position them correctly.

Disconnect the battery.
Drain the R134a coolant circuit using the filling
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
retaining bolt:2.1 daN.m
- Pipes to pressure relief valve
retaining nut:0.8 daN.m
- Pipes to condenser
retaining bolt: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.
