AIR CONDITIONING
Air blower unit
62
REMOVAL
An air blower unit can only be changed following
removal of the evaporator (refer to the
"Evaporator" section).

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

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).

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).
