Zdeno Posted March 16, 2004 Share Posted March 16, 2004 I bought the expansion valve for my 1991 LS with 168K , today (last part what I need to my A/C be good again, I hope) and would like to ask you guys if I have to drain off all the freon when I will exchanging expansion valve. You know guys I want to exchange the valve by myself and then to take the car to the service to they exchange the compressor and drier. My guess is that I have to drain off it. Am I right ?? Thank you !! Quote Link to comment Share on other sites More sharing options...
obergc Posted March 17, 2004 Share Posted March 17, 2004 You will definitely be removing the gas from the a/c system if you replace the expansion valve, no choice. Quote Link to comment Share on other sites More sharing options...
VBdenny Posted March 17, 2004 Share Posted March 17, 2004 Good to hear from you Curt. If you need to drain R-12, you really should find a way to evacuate and recycle. Then you will need a vacuum pump to completely eveacuate the system. The most important thing is, to make sure your oil charge doesn't change. Too much or too little and you have a big problem. I ususally do my own as I have all the equipment accessible, not to mention that I have 30lbs. of R-12. Quote Link to comment Share on other sites More sharing options...
Zdeno Posted March 17, 2004 Author Share Posted March 17, 2004 Thank you guys. I need to change the compressor and drier anyway so I´ll let change the valve at the same time and I think I will need new freon. I Already have R134 in it. thanks again Quote Link to comment Share on other sites More sharing options...
2XLexV8 Posted March 18, 2004 Share Posted March 18, 2004 Good Evening, May I ask why you are changing the compressor, drier, and expansion valve on an R134a system? Is it completely dead? Quote Link to comment Share on other sites More sharing options...
