viali8 is an unknown quantity at this point
does any one know anything about freeze 12 (not r12). I was getting a valve cover gasket this morning and told the guy i was going to have my ac system changed over to the r134a stuff. He asked my why and then showed me this freeze 12 stuff for 10 bucks a can. can this do damage to the system or is it ok? i have been reading some articles on line and some said to either pick r12 or 134a. is it ok to put nock off freon in the system. any help is appreciated. thanks

It is your car so you can do with it as you please. However, what refrigerant is currently in the system (R 12 or 134a)? If you go to freeze 12. and then ever take the car to AC shop and they discover what is in the system, they may refuse to work on the car. I would stay with what is currently in the car unless it is R 123 and you decide to convert to 134a.

Keep in mind that your A/C system is a enclosed system and won't "use" freon. If you have to add freon at all, you have a leak. Freeze 12 is no beter than R12. They both damage the ozone layer, don't belive me, read the can. With freeze 12 you don't have to flush and refill your A/C system as with a 134a change over.

A 134a conversion (done right) will work as good as any R12 system out there. If you really want to freeze your but off, install a 134a condenser and drier with the stock R12 evap core. I have seen vent temps at around 30 deg. With 100 deg @ 70% hum. out side worth the bucks if you live down south. (This setup has known to ice over the evap. at times, Just so you know)
