What year did they change R12 to R134a?
When the automotive industry made the shift to R-134a back in 1995-1995, they all published Technical Service Bulletins that covered retrofit procedures for their various makes and models.
Can you still use R12 refrigerant?
It became known as R12 or Freon. When used in refrigerator and A/C systems, R12 cooled incredibly well. And it was safe—neither poisonous to breathe, nor flammable. International manufacturing of new R12 ceased in 1996, but existing R12 can still be reclaimed and purified.
Can I mix R-12 with 134a?
No. Federal law prohibits topping off an R12 system with a different refrigerant. Or you can convert the system using one of our R134a retrofit kits, that will allow you to now add 134a refrigerant to your automotive air conditioning system.
Can R12a replace R134a?
It’s illegal to vent R134a into the atmostphere! You don’t just blow it out! Just adding R12a to a 134a system doesn’t work very well because a 50/50 mix is very inefficient. If you don’t have a vacuum pump, you can still make it work though.
Why did they get rid of R12?
In conclusion folks R-12 Freon was banned due to the damage that it caused to the Ozone layer. The Chlorine found in CFC refrigerants like R-12 would not break down in the atmosphere when vented or leaked. The Chlorine would then erode the Ozone bit by bit.
Is there a replacement for R-12 Freon?
There is now a direct replacement for R-12 on the market from Houston-based Pennzoil, called FR-12 and carrying the brand name FRIGC (pronounced frij-ik). There’s some good news for owners of cars that use R-12 Freon refrigerant in their air-conditioning systems.
How much refrigerant is in a Toyota 4Runner?

Do you need to convert R-12 refrigerant to R-134a?
If you drive an older vehicle (pre-1994), the air conditioning system contains R-12 refrigerant (Freon). As long as the A/C system has no leaks and it cooling normally, there is no need to convert from R-12 to the new “ozone safe” R-134a refrigerant.
Can a refrigerant retrofit be done on a R-12 vehicle?
If the vehicle has barrier style hoses and the compressor and seals are compatible with R-134a, the only thing that has to be changed is the compressor lubricant. A retrofit can be done one of two ways.
