FREON!! but you can convert it to R-132a. Buy a kit on any auto parts dealer.
R134a
R134a freon......
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.
All 1996 and newer vehicles use R134a refrigerant, which is available for the DIY at an auto parts store
FREON USED IS R-12
134A FREON IS USED.
