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.
