pigmaster Posted June 22, 2009 Share Posted June 22, 2009 A while back I pulled out my engine on my 91 legacy. To make it easier, we emptied the AC line (very little left in it), and removed the compressor completely. Since I wouldn't easily be able to recharge the line I never put the compressor back on. Now that it is blazing hot, and I'm living in a busier place so I'm stopped more often so I don't get the advantage of windflow, I'm wanting to put AC back in my car. I still have access to the original compressor that came off, but I hear I need to get a 'kit' to upgrade it to support r-410A (?) since the original stuff that came out is now an enviromental hazzard. What would be the easiest way to go about getting AC back on this? Is it possible to get a compressor from a new legacy and charge that? Or could I put the original back on and try and find a shop around town that would recharge it? Or should I find this kit and install it? Thanks!

ericem Posted June 23, 2009 Share Posted June 23, 2009 your best bet is to hook everything back up the way it was. Did you cap everything though ? Supposedly you need to replace the drier to. You can use over the counter r12a refrigerent. I would also get a bottle of stop leak. You will need 4 cans. Just need to pull a vacuum first. If you know someone in hvac they can pull a vacuum for you. Link to comment Share on other sites More sharing options...
Rooster2 Posted June 23, 2009 Share Posted June 23, 2009 My suggestion is to reinstall your old A/C compressor, if it was working properly prior to removal. You will prolly want to use new "O" ring seals when hooking up the lines. A new dryer would be nice, but not necessary. Suggest then going to an automotive shop to have refrigerant 134a installed in the system. Yes, the 134a conversion kits work well, but since it is necessary to draw a vacuum on the system to rid if of atmospheric air and moisture, you will need to go to a shop to do this. I had a 91 Leggie some time back. The 134a conversion gas works well in the system. Good luck! Link to comment Share on other sites More sharing options...
Legacy777 Posted June 24, 2009 Share Posted June 24, 2009 134a works fine in these systems. I'd suggest reading over my tutorial on the Legacycentral BBS http://bbs.legacycentral.org/viewtopic.php?t=1083 My only suggestion/change to that tutorial would be to flush the system out, and use PAG 100 oil instead of esther. Esther does not do as good a job lubricating. Link to comment Share on other sites More sharing options...
