Other type of quick-release hose clamps.
REMOVAL
The radiator is removed after first removing the
air blower unit, the dashboard and the air distri-
bution unit.
Engine compartment end
Fit a hose clamp and disconnect the quick-release
clamps from the heater hoses.Fit a deflector and blow out the remaining liquid
using compressed air.
Remove the heater pipe flange bolt on the bul-
khead.
Passenger compartment end
Unclip the four securing clips (E) and take out the
radiator.
REFITTING
Refitting is carried out in reverse order to remo-
val.
Fit two mounting bolts (F) onto the body of the
unit if the clips have broken.

In the passenger compartment
Remove :
- the air distribution unit,
- the heater unit radiator.REFITTING
Check :
- that the wiring is correctly routed behind the
dashboard,
- that the air ducts are correctly secured to pre-
vent noises developing.
Change the steering wheel bolt (pre-bonded bolt,
tightening torque : 4.5 daN.m).
IMPORTANT : 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
repair manual.

Are they correct?
Check that the air extraction circuit
is not blocked.
Repair if necessary.
Does the fault persist?
Is it a passenger compartment

Remove the heater radiator.
It must be blocked, clean or change it
(only valid for vehicles which have been
driven without the particle filter).

With the engine cold, remove the engine
coolant thermostat and check that it is not
jammed in the open position.
Is it correct?
Check that there is no unwanted intake of
cold air into the passenger compartment
(seals, grommets, cables ...).
Repair if necessary
Does the fault persist?
Check the air inlets (particle filter)
and outlets.
Partially blocked air inlets or outlets
reduce the flow of heated air
into the
passenger compartment.
Repair if necessary.
Does the fault persist?
The heater radiator must be blocked. Remove
the radiator and clean or change it
(only valid for vehicles which have been
driven without the particle filter).

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.

REMOVAL
It is not necessary to use a lift.
Drain the R134a coolant circuit.
Disconnect the battery.
Remove:
- the plastic air deflector on the upper crossmem-
ber,
- the seal (1),
- the upper crossmember (2),
- the retaining bolt (3),
- the two R134a coolant pipes (4) (fit plugs to
prevent the entry of humidity),
- the two radiator upper retaining bolts.Move the radiator-condenser assembly as far back
as possible towards the engine.
Remove the four condenser to radiator retaining
bolts (6).
Carefully remove the condenser.
REFITTING
Proceed in the reverse order to removal.
Check the condition of the seals.
Create a vacuum, then fill the circuit with R134a
using the filling equipment.
IMPORTANT
When changing the condenser, add 30 ml of
P.A.G. SP 10 oil to the circuit.
NOTE: tightening torque of bolts (6) : 0.8 daN.m.

13828R1
Remove the dehydration canister from under-
neath the vehicle.
Fit plugs on each hole to prevent any entry of hu-
midity into the components.
REFITTING
Proceed in the reverse order to removal.
Check that the seals are in good condition and lu-
bricate them with
P.A.G. SP 10 oil.
Create a vacuum, then fill the R134a coolant cir-
cuit using the filling equipment.
When changing the dehydration canister, add 15
ml of
P.A.G. SP 10 oil to the circuit.
NOTE: tightening torque of bolt (2) : 1.2 daN.m
REMOVAL
Drain the R134a coolant circuit using the filling
equipment.
Remove:
- the two radiator upper mounting bolts,
- the two mounting bolts which secure the pipes
to the dehydration canister.
Move back the radiator-condenser assembly
slightly.
Through the bumper, remove the two dehydra-
tion canister to condenser retaining bolts (1).
