i'm desperately in need of a can of r12 refrigerant. mine is runnin out and needs charging. unless i want to have the whole ac system drained and evacuate the condenser accumulator and everything to be replaced with like 134 i think i need a pound of r12.

EDIT- sorry man, but you'll have to post a classified ad, we're not allowed to have sale ads or requests on the boards.

 

sorry Jay, wish I could help, I need a pound or so myself...

 

Since R12 is a discontinued refrigerant you'd only find some at a specialty shop that does AC recharges and whatnot. R134 is the replacement for that but be warned. If you do plan to change to 134 use only 80% of the R12 that is supposed to go in there. R134 is a higher pressured refrigerant and would turn your AC system to crap is you put too much in. If you do happen to find some R12 remember to ALWAYS fill it up on the low end side otherwise you'd have to get more when you blow all the pressure out.

 

that applies to recharing with r134a as well. if you connect it to the high pressure side, you run the risk of the can exploding from the excess pressure, and injuring yourself.

i stock a generic recharge kit at napa that costs $29.99 plus tax. any napa store should carry it.

 

umm... R12 can only be baught if you have the proper licence for it. R134a can be gotten at any parts store and i know i have a case for the retrofit in my garage. R12 can also be found at any parts store. they are expensive for one can. I got the retro kit that came with 3 cans and all teh hardware for 40 last year.... but mind you, that was with teh discount. R12 is a lot more then that.

 

since i have had r12 in the system already don't i have to bleed the system and evacuate all the r12 thats left in there? i could be wrong but i think thats what i heard. i know nothing about ac systems except how to delete them!! if i do have to bleed the system how do i do that??

 

i belive you can add it to teh system and not have to evactuate anything... only way you would have to do that is by using R134a where the oils dont mix. I suggest you get a R134a retrofit kit done to your car, because if you plan to keep this car, or keep it in good shape, a retrofit would be a good idea for later on when it needs to be refilled. Its A LOT cheaper in the long run. Its like 110 to retro fit, or 100 to fill it with R12.... then if you retrofit, then all you have to do from there on is get a can at your local store, and fill up your system.

 

There used to be a website - can't remember the name- where you could get certified to buy R12 online. You had to take a test (online) after studying (cough) the online book, and they gave you an hour for the test. That was years ago... if I find it on my computer somewhere, I'll put it up.

If there was a leak, you might need to hook a vacuum pump up to the system to "suck it empty"... I forget the numbers but there needs to be a certain level of vacuum (not pressure) inside the tubes. Harborfreight.com used to sell a $20 vacuum pump, but, of course, you needed an air compressor to run it.

And who needs a/c? Just yank the whole system out like I did. Of course, I love the heat...

 

Cool, they're still in business. http://www.epatest.com to take your test! You might want to fix any leaks, anyway... R12 is expensive. It's illegal (at least in the US) to make any new R12; all the R12 that you buy is recycled. That's why it's so expensive... the dying supply, and the recycling.
