Hi guys. A while ago when I replaced the alt belt, I accidentally undid the a/c line underneath (stupid, but this is how we learn). I got a nice blast of refrigerant and I assume the whole system is now voided. Will I have to take this to a professional for a machine job or will a few cans of recharge stuff take care of it? Should I pressure check first to gauge?
Thanks in advance! This post has been edited by SwissFerdi: Jun 14, 2016 - 11:35 AM -------------------- '97 ST \ Eibach \ KYB \ Kenwood \ Alpine \ Cusco \ OEM+ [sold 10/18]

I did a DIY recharge when I replaced my condenser at home on the 7G, it also contains the dryer though. $50 vacuum pump, borrowed cheap gauge set from my friend, can tap, and a 12oz can of 134a I grabbed on sale. I got enough charge to run the system to make sure it worked then topped it up at the shop. The biggest trick is to put the 134a can in HOT HOT water so the pressure rises and you can get more of the can in there, I had nothing but vapor in the can and not even very much of that. If you charge that way you can get close to a correct charge and verify the system is working, cooling, and not leaking. Charging by low/high pressure is fairly close to charging by weight, that's how my Celica is charged right now since the scale is a little off at work.
