What type of refrig. does the AC use in a 92 dodge caravan
Unless the labels are missing from the car, it will state which type of refrigerant is used. Could be either R12 or R134a. If originally R12, it could have been replaced by R134a with an upgrade kit. The easiest way to tell if the labels are missing, is to look at the valves on the AC system. If they are Schrader valves (same as used on tires), then it is the older R12. If the caps are Red (high pressure side) and blue (low pressure side), then it is R134a. The sale of R12 to non-certified mechanics is illegal in all states as far as I am aware. R134a is available in most states and retro-fit kits are available in most states.
I have done the retro-fit on 2 vehicles with acceptable results. It is recommended to remove all the old R12 with a vacuum pump. Autozone (in my area anyway) rents these.
Good luck if you need and decide to retro-fit yourself.
