Message	I have searched and got some info.. but I have some questions. I know there are the retrofit kits that allow you to run R134a in an otherwise "stock" R12 system. I have heard mixed things about using R12 compressor and lines with R134a refridgerant. Some say it works with no problems.. some say it will kill the compressor, leak from lines etc. I am currently doing a TT conversion on my 90 2+2. I figure now is a great time to convert the system. I plan on replacing all O-rings and drier and condensor. I have all the AC lines from a 95' TT as well as 95' AC compressor. However; would I be able to use those lines with my 90 Evaporator? Would it just be easier to use a retrofit kit, leaving my lines native R12? Or should I change out the whole system to 95' style, 95 compressor, 95' evaporator etc.? Please let me hear your views and what you have done.. and most importantly.. what has worked for you and how long has it been? Thanks alot!

I found this.. - KongZTT GT28RS MD 18:47:31 02/13/13 I wonder how he "flushed" the condensor? Compressed air? (n/m) - Jayru 20:21:29 02/13/13 duraflush - aliaZ 21:35:45 02/13/13 Yep.

I believed you - LivinTheDream 21:16:20 02/13/13 So the gasket thread selant goes on all the O rings - Jayru 21:56:38 02/13/13 Goes on all threaded fittings not the o-rings themselves. - LivinTheDream 23:37:28 02/13/13 nylog is primarily an o-ring lubricant - aliaZ 23:48:12 02/13/13 Damn. Guess I messed up on that part of the install. Sorry - LivinTheDream 19:18:34 02/14/13 no worries (n/m) - aliaZ 06:32:55 02/15/13 I just recently installed all of the AC components back into - Ash's Z 07:20:48 02/14/13 the problem is the TSV is calibrated differently for R12 - aliaZ 06:39:46 02/15/13 Nice - good to know. (n/m) - Ash's Z 12:01:26 02/15/13 The key to a successful conversion is a thorough flushing - aliaZ 06:55:36 02/15/13
