I yanked the whole AC system (drier, condensor, evaporator, compressor and lines) out of a Civic, and I think it was a 93 with R12. I'm ordering parts and plan to buy another drier, so I need to know if I have to stay with an R12 drier even though I plan to convert to R134A. Now, I'm not 100% sure that the system was R12, so is there any way to check?

If it matters, the system is going into a 1993 Civic CX with a 1995 Acura Integra GSR engine and I'm using the 1997 CRV P7J AC bracket.

 

The filling plugs tell you.

The type of gaz is also wright on the sticker on the compressor.

 

ok, thanks. I didn't see the sticker under all the black filth on the compressor.
