79 A/C Freon
How can you tell what type Freon you have in your system. My '79's compressor was changed out in '99. I have looked at the label on the compressor and it makes no mention of Freon. The compressor is the short "pancake" type not the long cylinder type. It has one fitting on it that looks like a tires valve stem. Thanks for any post.

More than likely it has the r-12 in the system atleast that is what came from the factory. You can look at the servicing fittings and if the servicing ports still have the screw on type the system probably has not been modified. R-134 servicing fittings have a kind of slip on device like what you would have on your air compressor in your garage.

I agree that it is probably R12. However, believe it or not my friend is Mr. Goodwrench and converted my AC over to R134 by just changing out the fittings. Guess he also vac'd the system and maybe put in some different oil. Anyway the AC has worked fine for the last three years. Not what I'd say was cold enough to "hang meat" but is good enough to keep you cool if you decide to put the T's back on.
