How many pounds of freon can a Hyundai Elantra take?
It contains no Freon. Freon or R12 has been banned for years and is no longer used as a refrigrant. It more than likely is charged with R-134a. If it needs recharging then it has a leak and the leak needs to be repaired. It is illegal to recharge an A/C system without first repaiing the leak. Take it to a professional.
