R12 to R134
 

I read some time ago, I think in Car Craft where they pumped R134 into an older a/c system and in their words "blew like winter". But I'm quite certain it wasn't a Ford, I don't know if that's an issue or not.

Is there an inexpensive solution here? I just put a new a/c condensor on my 86 5.0 so the system is empty right now.

Has the price of R12 come down? Should I just stick with R12 and forget about it?

R-134 won't cool as well in a Mustang as well as R-12 due to the size of the standard condenser. I converted my '89 last summer and it does a fair job, but not as good as it was.

If you convert, basically, you should replace the evaporator/drier, flush the oil from the system, change the oil in the compressor and install the proper oil for R-134. If you can swing the cost of R-12, use it.

Go to http://www.ackits.com and read the message boards and information about the proper way to do the conversion.

My car was converted from r-12 to r-134 and blows very cool, I was pleased with the conversion.

I still cling to the R-12 b/c, as was stated before, it cools a hell of a lot better than R-134. I live in Florida though and one you need is AC.
Interestingly, the tree huggers have discovered that R-12 isn't the satanic evil they thought. It is still expensive though, about $50 a can I believe.

Gee, I wonder if I could drive it over to Mexico and get it charged for cheap? Hmmmm.....

Mine works OK too...
 

We converted my '69 to 134 several years ago... it seems to work just a good as before... I think my friend has a case of R12 stashed away... he might want to sell it by now... I'll check with him if anyone is interested...

I live in florida also and deal with this hot humid climate all the time, the 134 cools just fine, get it done by a proffesional and you'll have no problems with cooling.
