Before carrying out any work, check that the customer uses the air conditioning
correctly.
Non regulated air conditioning.
Check the level of coolant in the cooling
circuit.
NOTE: if the coolant level is too low, the cir-
cuit may become unprimed when driving at
low load and at idle.
Repair if necessary.
Does the fault persist?
Visually check that moving the control
moves the mixing flap.
Does it move?
yes
Check the coolant circuit.
NOTE: fitting an oil, water or air cooler which
has not been approved by the research centre
and which is incorrectly connected may re-
duce or even stop the flow of coolant in the
heater radiator.
Repair the coolant circuit if necessary.
Does the fault persist?
Remove the heater radiator.
Clean or change it if necessary.
Check that the components which were removed are connected correctly.
Check that the system operates correctly.

AIR CONDITIONING
Evaporator
62
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.

REMOVAL
An air blower unit can only be changed following
removal of the evaporator (refer to the
"Evaporator" section).
Remove the two heater fan assembly mounting
bolts.
Remove the heater fan assembly.
REFITTING
Refitting does not present any special points.
After refitting the heater fan assembly and the
evaporator, create a vacuum and then fill the
R134a coolant circuit using the filling equipment.
IMPORTANT
Ensure that all of the seals are positioned correct-
ly. Lubricate them with
P.A.G. SP 10 oil.

Compressor
62D7F ENGINE
13829R1
REMOVAL
Drain the R134a coolant circuit.
Disconnect the battery.
Remove:
- the compressor drive belt,
- the two connecting pipes (A),
- the retaining strut bolt (B),
- the three compressor retaining bolts (C).
Remove the compressor.
NOTE: it is essential to place plugs on the pipes
and on the compressor to prevent the entry of hu-
midity into the circuit.
REFITTING
If it is changed, the compressor is supplied filled
with oil.
Position the compressor the correct way round
(filler plug facing upwards).
Tighten the three bolts (C) (Tightening torque:
2.1 daN.m).
Fit the strut retaining bolts (B).
Refit the two R134a coolant pipes (A) on the
compressor (Tightening torque:
2.1 daN.m).
Fit the drive belt and tension it.
Create a vacuum, then fill the R134a coolant cir-
cuit using the filling equipment.
NOTE: when refitting the connecting pipes on the
compressor, it is essential to fit all the bolts, then
bring them into contact before torque tightening
them. The aim is to ensure that the pipe is positio-
ned correctly so that it is not damaged at the cut
off (1).
Check the condition of the seals and lubricate
them with
P.A.G. SP 10 oil.
IMPORTANT
When changing the compressor, it is essential to
top up the oil.
