R12 refrigerant has been banned from import for decades, so any vehicle still on an original R12 system either holds a very old charge or has already been converted. Retrofitting to R134a is straightforward when it is done properly and a disaster when it is not.
A correct conversion means flushing out the mineral oil, because mineral oil will not circulate with R134a and the compressor starves; renewing seals and O-rings to R134a-compatible material; fitting barrier hose, since original hose is porous to the smaller R134a molecule; changing the drier; and fitting the correct service ports with the charge weight recalculated to roughly 85 to 90 per cent of the original R12 figure.
We enjoy this work and we do it on everything from Australian classics to imported project cars.
