92 Camaro A/C with R12

Posted by mapesii (My Page) on

I have a 92 Camaro with R12 A/C system. When I got the car it had set for a while. The A/C works but not real effiecent. The compressor seems to cycle on and off way to often. I have not hooked up my gauges to it yet but my guess is it is a little low on R12 from the long sit. My question is I have seen a product called Freeze 12 an R12 substitute. Can this be used in my system and without doing a complete evacutation and recharge(mixing the two)?

Don't think so. If it were me, I just take it in for service. Dispite all the horror stories about r-12 being $100 per pound, it only cost me maybe $20 more to have my r-12 system serviced a few years ago than had it had 134a. Maybe it's a regional issue. Maybe there's some shops trying to cash in. I know for a fact r-12 isn't hard to get.

Your vehicle will cool much better with the R12 that the system was designed for. And as stated above its not that expensive if the only problem is a low charge you may get off cheap at a shop. The Freeze12 is 80% or so R134a with I think 20% R142B. You are still supposed to have the epa cert 609 to purchase this stuff and if you get that heck I would just pick myself up some r12 if you wish to DIY. Mixing the two refrigerants will create a whole new blend Not Recommended
