There should be a sticker under the hood some place. You can tell by the test connections where you hook up the gages. R-12 has 1/4" flare (about 1/2"od)and the R-134a has a much larger one (maybe 3/4"?).

It should use R-12. I believe 1994 was the first year the automotive industry used R-134a

If it uses R-12 then if you need some extra then you can add freeze 12 which will work with R-12 and you don't have to have a license to buy the stuff and is cheaper than even 134. My mechanic has bought freeze 12 for me in the past and a friend has informed me that you do need a license to purchase freeze 12 so i'm not sure if you do or not now. All in all the freeze 12 is compatible with R-12 and is indeed much cheaper.

'94 was the first year for R134. If I'm not mistaken, all of the '94's I've looked at had it. As stated above, it's clearly marked on a sticker on the compressor.

Actually, on automotive R-134 I believe they are all using the Quick connect type fitting. Industries way of making sure we dont confuse them. I know in commerical refrig. they are using a flare fitting which is slightly larger then a standard R-12, R-22 hose fitting.

I've never heard of "freeze 12". What is that, is that even freon? BTW, Dodge used R-134 in my 93 intrepid.
