r12 but get a 134 kit and change it over for about 35.00 (wallmart) you have to be a regesterd mecanic to get r12
Was built for R12, should be converted to R134a
never use it
R-134
A 1982 Oldsmobile was built to use R12, it would need retrofitted to R134a..
it takes r134a freon
R134A
FREON USED IS R-12
It does not use Freon as a refrigerant. It uses R134 refrigerant.
its probablly r-134-a freon
R134s freon
BY "freon" do you mean R-12? If so then the answer is no. The system uses 134A refridgerant and does not need to be converted.
Only if you replace the Dryer, install adapters on the lines, and use compatible oil.
