What type of freon does a Toyota Camry use?
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.
