R12 Freon for 944's
Was somebody looking for some R12 recently? If so I have two 12oz cans of Dupont R12. $15.00 each plus shipping.
I realize this should be posted in the for sale section, but thought I would offer it to a 944 guy first.

Can you even ship R12 anymore? Or does it have to carry a hazardous label?
And if the other guy never shows or doesn't want 'em, can I get them? Do you have a tap to go with them? EDIT: Damn, too late. :P

hmm.. he raises a good point...
need to ship via a means that isn't border checked... I'll take both cans by the way..... oh, are they real R-12? or is it that fake "freeze-12" stuff you see on ebay all over?

I was trying to fit my '83 944 with 134a but..... I can't find the low pressure side. I can see one attach point by the left head lamp but it appears to be on the High pressure side, Help please it was 42'C today and I have Black interior, the 2-60 AC I am currently using (2 windows down at 60mph) can't keep up
Would it be better to find some R-12 if anyone has any left and fill it that way?

Oh crap is it the one that points at the alternator
had an unsettling feeling that the only fitting I could see was the High pressure one OH and one more quick question I saw two different brands of 134 one said to hold the can upside down the other said to hold right side up. I have always held the belief that Liquid doesn't compress and may crack a compressor open so I have never held a can of refrigerant upside down to let the liquid freely go into the low side. though I have watched people put a full can of 134 in the High side before starting the engine on an empty system is this a good idea??

and while someone is answering that question, can someone tell me how to free a system of existing R12 before I do a re-charge?
I know you technically should go to a place and have it done because it's illegal to just vent it into the air.. but is there a way to do it yourself? legal or otherwise? for strictly educational purposes only, of course....

Open the high pressure side valve with the car running with AC on, that should clear the system out. or hook a vacume pump to it

just do it out side and try not to get refrigerant on your hands/eyes can cause severe frostbite, and the oil is an irratant.
if you release the R12 or 134 in a small garage while laying on the floor it could possibly rarely cause breathing problems or um very rarely death, so um yea do it outside while your neighbors aren't looking. and if anyone questions your actions say the valve stuck open um yea that'll work. Oh by the way I don't condone participating in Illegal activities thats why I never got those nine speeding tickets that um are somehow parking tickets  Love you Mr. and sometimes Ms. DA

okie, so just to be clear... process is as follows..
-open high side (will the R12 come out immediately? or do I need to tap the valve somehow? -turn on car -turn on the A/C and let run -refill with R12 do I need to add any oils or anything? there's a "free" a/c check place around the corner.. might be worth my time to go in and see how "free" a pressure check would be..

NO! Do not run the compressor while evacuating the system!
The Freon is also the carrying medium for the compressor lubricant, if the compressor runs with low Freon, it has a _very_ good chance of seizing. This is why the cars have a low-pressure cut-out sensor that shuts down the compressor if the pressure of Freon drops below a certain point. The only way to get the R-12 out is to pull a vacuum on the system for a few hours. Furthermore, you _cannot_ just put R-134a in after evacuating the R-12. You need to replace the condensor (if you want adequate cooling, R-134a will use a larger condensor if available) and will definitely need to replace the receiver/drier as well as changing the compressor oil. THe oil that is used with Freon does not dissolve into R-134a and so is not carried through the system with R-134a. This means that just dumping 134a into an evacuated R-12 system will eventually result in compressor problems. Take the car to a qualified shop unless you're just dumping R-12 into it. Aaron

Another thought, why on earth do you need to evacuate the old R-12? It doesn't wear out. Just charge the system with new R-12 (on the low-side port) with the engine running and the A/C on. When the sight glass is clear of bubbles, you're good to go.

Just to clarify a few points:
1. It is "real" Dupont R12 2. It can be shipped in the US, not sure about international. 3. You do not need to remove your old R12. 4. I assume you are either EPA certified or buying for resale. Eldorado has first grabs at it, if he falls through, AaronM has it.

Oh can anyone tell me for shure that the port behind the left headlamp is the High side or low pressure side. From tracing all of the lines it looks like the High side BUT everyone I talk to is conflicting.

It is the HIGH side port. The low side port is on the suction port of the compressor accessable from underneath the front end on the drivers side.

timely post!, I've been intending to add some r12 for a while now. Is it easy to see the low-side under the car?, it looks like I'll have to jack it up, can you follow an ac line from somewhere?
If I have what's pictured below, should that be easy to do? Is there a quick step-by-step available somewhere?
