Removing
Removing
Special tools and workshop equipment required
   
t  Torque wrench -V.A.G 1331/- (5…50 Nm)
  W00-0427
t  Air conditioner service station -VAS 6007A- or later model.
  Note
t  The refrigerant circuit must be purged with refrigerant R134a under the following circumstances:
t  If dirt or other contamination is in the circuit.
t  If during the evacuation of a leak-tight refrigerant circuit the vacuum is not maintained at the gauge (there is moisture in the refrigerant circuit and this generates vapour pressure).
t  If the refrigerant circuit has been left open for longer than normally required for repairs (e.g. following an accident).
t  When pressure and temperature measurements in the refrigerant circuit indicate that there is moisture in the refrigerant circuit.
t  There is doubt about the amount of refrigerant oil in the refrigerant circuit.
t  The air conditioner compressor has to be exchanged because of internal damage (e.g. noisy or lack of power).
  W00-10176
t  If only the ancillary bracket is to be removed, the refrigerant lines on the air conditioner compressor need not be loosened: it is sufficient to secure the air conditioner compressor to the body with suitable material, e.g. welding wire.
The procedure for purging with refrigerant R134a is described in ELSA under Heating, ventilation, air conditioning system; Air conditioning system with refrigerant R134a → Rep. gr.00 Technical data; Clearing refrigerant circuit of contaminants.
Notes on repair work to vehicles with air conditioning and on handling refrigerant can be found in ELSA under Heating, ventilation, air conditioning system; Air conditioning system with refrigerant R134a → Rep. gr.00; Technical data.
Notes on testing equipment and tools for repair work to vehicles with air conditioning can be found in ELSA under Heating, ventilation, air conditioning system; Air conditioning system with refrigerant R134a → Rep. gr.00; Technical data.
  N87-0382
–  Extract refrigerant, e.g. with air conditioner service station -VAS 6007A- before opening refrigerant circuit. Observe notes → Chapter.
–  Remove noise insulation under engine → Rep. gr.50.
–  Remove poly V-belt → Rep. gr.13.
  WARNING
Danger of freezing injuries.
If refrigerant circuit has not been evacuated, refrigerant will escape.
Extract refrigerant before opening refrigerant circuit. If the refrigerant circuit is not opened within 10 minutes after it has been evacuated, pressure may develop in coolant circuit due to re-evaporation. Extract refrigerant again.
–  Detach connector from air conditioner compressor.
–  Remove bolts -4- and separate refrigerant lines -2- and -3- from air conditioner compressor -1-.
–  Remove securing bolts -5- and remove air conditioner compressor.
