DATE: Aug 1, 1994
SUBJECT:
R-134a Refrigerant System Components, Replacing and System Capacities
MODEL(s):
Golf III, Jetta III, Passat, Corrado, EuroVan From m.y. 1993
This Bulletin Supercedes Technical Bulletin Group 87, No. 93-01, issued May 10, 1993
CONDITION
Replacement A/C compressors, evaporators and condensers are filled with Nitrogen.
Replacement A/C compressors are filled with the total refrigerant oil (PAG oil) quantity needed for the entire refrigerant system (except for EuroVan
models with two evaporators).
SERVICE
If Nitrogen gas does NOT escape when the caps are removed from a new compressor, evaporator or condenser, the component may be leaking, do not
install.
Always replace the receiver drier whenever the refrigerant system has been discharged due to leaking or damaged components.. Keep refrigerant system
and replacement components sealed for as long as possible to minimize the chance of dirt and moisture contamination.
If the system has been discharged due to a damaged or leaking component (hose, pipe, compressor, evaporator, condenser, etc..), flush the refrigerant
system first with compressed air, then with nitrogen (available locally). This will remove the refrigerant oil which may be saturated with moisture.
If a new compressor is installed, do not add any additional oil (except for EuroVan models with two evaporators) as the total amount of oil required is
already in the compressor.
Follow all Cautions and Warnings listed in the Repair Manual, Repair Group 87 when working on an R-134a A/C system.
Refrigerant R-134a
Obtain R-134a refrigerant from a local A/C supplier under one of the following names:
^ R-134a
^ Tetrafluoroethane
^ CH2F CF3
^ SUVA(R) TRANS A/C
^ ARCTON(R) 134a
Note
R-134a refrigerant is packaged in different containers. One variation is SUVA(R) COLD MP used only for commercial applications. This type of
R-134a is sold in cylinders using a 1/4 flare fitting which will not connect to the 1/2"-16 ACME fittings used on the vehicle and servicing equipment.
Use only R-134a which comes in containers having the correct type of service fitting.
