What refrigerant is used in a 1994 Ford Aerostar?
An A/C shop will know. The leak must be repaired before adding refrigerant.
It is R134a. Please under NO circumstances use the refrigerant that has stop leak added. If you have to take it to a repair shop and need repairs, it will ruin the equipment that is used to recover the refrigerant. Also, you need to be exact in the amount that is in the system. There should be a sticker under the hood with all of the information on it.
All modern motor vehicles, including yours, use R-134A type refrigerant. Most vehicles prior to 1994 used the R-12 type refrigerant, which is now no longer used in vehicles, due to its chlorofluorocarbons which deplete the ozone layer. Since 1994, all vehicles are equipped with the R-134A, and any older vehicles that need air conditioner servicing are required to be retrofitted with R-134A, as R-12 is no longer produced and is outlawed. Hope this helps!
All devices used for refrigerant recovery must be certified by the EPA. If the device was manufactured before November, 1993, It must be capable of recovering 80% of the refrigerant in the appliance. If the device was manufactured after this date, it must be capable of recovering 90% of the refrigerant.
It depends on the year of the car. From 1994 on, R134a refrigerant is used. Prior to that, they used R12 refrigerant (Freon). R134a is technically not "Freon". Be alert, however, as many older cars (like my 1986 Camry) have been retro-fitted with R134a systems, and can no longer accept Freon, as the two refrigerants are not compatible.
