Use the freeze 12, it will work just like the r-12. You'll be very happy. I've used it in cars for several years now w/o any problems.
+1

Freeze 12 is almost identifcal to R134a (BTW) so it won't last as long as the original R12 did. But it will do the trick.

I'd swap if it were me though.

Just my $.02,
Ivan

What do you mean it won't last as long?

Well, so long as it will do no harm, I think I'll go get a can or two. Do I need pressure guages to install it, or do I just bung a can on in? Thanks for all the help guys.

The elements in the two (R12 and R134A) are different. The molecular structure of the two are similar in the aspect of they can both be compressed and the temperature will reduce.

However, the elements being different, R134A (Freeze 12) breaks down with repetitive thermocline cycles and the duty life of it is greatly reduced as compared to R12.

That's about what I could tell you without having to kill you...

You don't need to have gauges but just be careful. There should be a sticker on the condenser that tells you the amount needed to fill the systems completely...should be between 32-38 ounces.

Just don't put more than that in the system when you do it. I mean you can, but a check valve in the compressor will blow out the overage all over your engine once you turn it on and call for AC.

You know, the guy that figured out that my car had already been converted also said the R134 doesn't last as long. I believe you. So Karma, do I need guages to charge the system with cans from the auto parts store?

Hehehe..I was a Mechanical Engineer Major with a Minor in Fluid Dynamics. Then I got a part time job as a mech that turned into a job from hell. Then I gave my two weeks and now I'm a Mr. Mom until I decide to get another job.

Oh, yeah, I was also a Rocket Scientist when I was in the Navy..Just kidding. I did do alot of explosives and weapons and can tell you that there is 1.5 ounces of Tritonal in a Mechanical M904E4 nose fuze for a Mk 80 Series Low Drag General Purpose Bomb..

But that's another Thread.
