Adapter For Assembling Flushing Circuit

• The following table lists the different adapters necessary to connect the service station to the refrigerant circuit, to flush and to bypass the removed fluid reservoir or reservoir and expansion valve (depending on the vehicle).
• Using a charge hose with 5/8 -18 UNF connections (short version, for example Charge hose -VAS 6338/31-), connect the two adapters (contained in VW/Audi passenger vehicle set adapter chest -VAS 6338/1-) which have been installed for the removed reservoir or fluid reservoir.
• If a flushed refrigerant circuit is not to be reassembled immediately after the flushing, leave the adapters on the connections and seal the connections on the adapters with sealing caps -VAS 6338/30- (from VW/Audi passenger vehicle set adapter chest -VAS 6338/1-).
• Depending on the version of the A/C compressor and on the time period of production, various connecting and sealing technologies can be found on the refrigerant circuit. Refer to [For engine(s) BGP, BPY, BGQ, CBTA, CBUA, CCTA, CBFA] Description and Operation .
