Engine Size: 3.6
Refrigerant Type: R134
Country of Origin: Australia
Bought a used compressor, filled the system up with r134 and now the compressor turned out to be faulty! So i have to change the compressor!
Can i recover the r134, change the compressor, and have them refill the system with the same r137 that was recovered?
Yes, if you have the equipment to do this sort of thing.
That's the way its suppose to be done, least in the USA. But with so many different EPA approved blends out there, have to make sure, it is R-134a you are recovering. So now one is required to have a refrigeration identifier.
But the refrigerant is only half the story, other half is the oil, correct and precise amount, then additives may have been added that augment the problem. So the system has to be taken apart, new accumulator or receiver, has to be absolutely moisture free, and flushed. With a faulty compressor, the condenser should be replaced.
Sometimes its easier just to flush and leak test the evaporator and replace everything else for a reliable system. Really no short cuts with R-134a, was with R-12.
