Convert your automotive air conditioner from R-12 to R-134
Refrigerant.
If you have an older car it may have R12 refrigerant in the air

is a brief explanation of the procedure with a few insider tips
to help you. To begin you will need a conversion kit with all
the necessary materials. It will include: 2 new adapter
fittings, 2 -3 cans of R-134, and a hose with adapter. Once you
have all the materials, you can begin the process. The first
thing you have to do is have the R12 recovered with a
refrigerant recovery machine. (It is illegal to just open the
valve and let it out in the air.) Now that the air conditioning
system has no pressure, it is time to install the new valve kit.
