hey what is the difference between oil charge and the refrigerant on freeze 12?

[u3b3rg33k]

Buy duracool from the great white north. They have plenty of cold so send you cheap. I bought some Canadian cold, pumped it into the '30, and it's quite happy. I've been using it already to help keep the fog on the outside of my car.

bring it to a shop, shouldnt they do it for free because they can sell the r12?

and in cali they cant sell r12....but you can buy weed on the cornor! lol =)

ryann,

beleive it or not the system still has pressure...so i dont think there is a leak. now it might spring one when it is fully charged...
i think this might not be a diy project...

The primary problems with 134A in an R12 system are that their compressor lubricants are incompatible, and normal operating pressures are different. There is a product called "Hot Shot" that is compatible with R12 compressors/filter driers and the oils they use. Any experienced refrigeration mechanic will be familiar with this gas. Although it was not marketed as an automotive refrigerant, I have used it to recharge uncontaminated automotive R12 systems with success. Your main issue will be charging your system with nitrogen in order to figure out where your R12 went. Fix that issue first, then pump down and recharge.

that es-12a looks like the ticket...but how do i safely discharge the remaining r12..,?
just dumping it in the air aint right.....

im convinced that ES-12a is the best solution and it's what im going to with if i can find it locally. it's cheap, much more efficient, easier on the compressor, doesnt leak as well and not anymore flammable than r134a.

I only needed 2 cans

[619E30]

If you come down to sd I can do it, I have a bunch. 10 bucks a can

[gone002]

r12 is getting cheaper and cheaper actually. there are fewer and fewer cars out there that run r12. you can find cans on craigslist, and most shops still have it. don't convert to r134 unless you have to, it sucks compared to r12.

for example:

wow dude at f**kin around ! he hit me up already..how many cans do i need?

[gone002]

Just get Duracool. Best $20 I ever spent. Or drive to TJ and get it refilled with R12. Don't get shot.

yeah i wont be driven to TJ unless in need a burritto and an open gunshot wound!

i looked everywhere for r12 no one will touch the stuff here in cali

for 50$ freeze 12 looks like the sheet!
how come none of the shops i talked to offered it?
