They look real to me Erik. Check out his other auctions. There is one with a dozen 12oz cans of R12 listed for $360 w/ a "buy it now" option.

Cant buy it anyways, gotta be EPA certified. Well i guess if some1 wants to have a big ol group buy of R12 and split it we need some1 whos EPA certified.

I'm certified. ;) Anyone can take the test Erik, it's a "open book" type test. All the answers are there, you just need to read through the booklet and then answer the questions. I believe they charge a $20 fee for the test that you include when you send it in. You should be able to pick up a test booklet from almost any parts store for what it's worth.

The test is $18. Just took it like a month ago.

Which brings me to my next point....I'm also certified. :icon_biggrin:

If you do ever buy..don't get fooled by Freeze 12. ITs not the same as R-12. Freeze 12 doesn't cool for jack compared to R-12. R-134a cools good if you change the WHOLE system over from R-12.

Fright tools sells a nice cheap vacume if you do ever drain your whole system. I have the $1K+ unit and the cheap Fright Tools air compressor powered unit...they work just as good. Pressure test your system. It could be that your dryer is full of crap and/or the orfice is clogging up.

Yea, and don't let anyone at a shop tell you it's ok to mix Freeze12 and R-12 together.. because it's not! Freeze12 is consists of 80% R134a, so mixing that with an older R-12 system is just asking for disaster.
This is why I've started to do my own AC work and learning things myself.
That auction link you posted had some affordable gauge kits, so I may have to pick one up sometime.

Prospeeder · July 07, 2006, 11:42:08 AM

Ah ic. So im curious, what all has to be changed to go to R134a? What components will I be able to keep?

pontiac6ksteawd · July 08, 2006, 11:40:11 PM

Someone recently did a write up on how to convert R-12 to R-134a. His conversion table is pretty spot on, but you really dont have to change all the O-rings that are suggested. I didnt and my system worked great for a year until the AC lines blew. Then I replaced the o-rings suggested cause they came with the new AC lines.

Prospeeder · July 09, 2006, 12:56:39 AM

im wondering if i Have R134a, any quick way to tell, like by the fittings? Because I have the sticker that says THIS VEHICLE HAS R12 blah blah and then right next to it is another sticker, but its all bleached out, and iv NEVER seen it on any other grand prixs, so its leading me to belive it might have said its been converted....

pontiac6ksteawd · July 09, 2006, 09:57:15 AM

The nipples would be completely diferent (but dont try using that line on your wife). R-12 will have threaded nipples that look like oversized tire valve stems. R-134a will have no threads, but a lip that should go completely around the outside edge.

eh its R12, crap

TurboGTU · July 13, 2006, 12:27:05 AM

:laugh: I've been buying almost everything there.

There was an oil type that the a/c compresso rebuild shop said not to use on any system that would lock up your compressor after a while. I'm going to ask pops which one it was.

Theres a method of saving the R12 that required putting the empty cans in watter and using a vacume (not the air compressor type) pump. But I don't think you wanto use dirty refrigent in a new, clean system. But this will keep the tree huggers types happy.

If your system seems to work fine after some pressure readings with the guages test...then you prob just need a recharge, with new dust caps just incase.
