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.

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.
