a 92 would have R12 in it, but they make a change over kit to use the newer stuff because R12 is next to impossible to get anymore.

I believe that the 134A is being phased out as well.

Check with you local auto parts store, they should be able to get you the kit and the 1LB cans of Freon.

Most part stores have kits that have about 10oz of freon included that connects to the high pressure hose. pretty easy to do.

1994-1995 are R-134a Factory equipped. 1987-1993 are factory R12 equipped however yours may have been retrofitted ti R-134a. The easiest way to tell is if the service ports have a cap with screw threads on the outside of the fitting underneath it is still a R-12 system if the service port has no threads on the outside it has ben retrofitted to R-134a.DO NOT add R-134a to a system that has not been properly retrofitted, it may work for a while but SERIOUS damage WILL occur sooner than later.BTW I am an ASE certified A/C tech (retired) and have extensive experience with retrofits.Feel free to pm me with any questions .Good Luck

There should be a refrigerant ID sticker under the hood. 92 is safe to assume is r12 because Chrysler didn't move to R134-A until 93. Careful with those so called conversion kits.....if all parts aren't switched out it may not work very well. Also if you do make sure you flush the system because if the R12 & R134-A mix it'll throw the pressures off and you'll have huge issues.

R 12 is not impossible to find. its all over craigslist. R 134a is not as cold and the system will never be as goo as an r 12 system. you can retro fit the system to accept r134

A PROPERLY retrofitted system WILL perform as good as a R-12 system.
Retrofitting is more than changing fittings,oil and refrigerant.All the parts in the system have to be in top notch condition,a modern condenser, a compressor in great condition and the appropriate expansion device.I have done literally thousands of retrofits and the only ones that were problematic were ones that the customer wanted to cheap out on.Once all the other demons are exorcized from my jeep I plan on adding A/C and you can bet it will be an ice cold R134a system.
