I have purchaed three 12 ounce cans of the "Freeze 12" brand R12 substitute refrigerant. Could someone please tell me what the capacity of the original R12 is on an '89 Legend A/C system, AND if the same capacity would apply to the Freeze 12 refrigerant when charging up the system? Thanks.

The capacity with R12 is approximately 2 lbs or 32 ounces.

I don't know what "Freeze 12" is, but I would think you would add it to the correct gauge
pressure. I wouldn't try doing that without a proper gauge set and make sure you add to
the low pressure (suction) side. If there is air in the system it needs to be pumped out with a vacuum pump and the receiver drier needs to be replaced.
