What type of refrigerant do you use for the air conditioning a 1991 Cadillac Coupe de Ville with 4.9 liter?

A 1991 Cadillac Coupe DeVille with a 4.9L engine likely used R-12 (Freon 12) refrigerant in its air conditioning system. However, R-12 is no longer manufactured or legally available for automotive use in most places due to its ozone-depleting properties.

If the system needs recharging, it must be converted to a refrigerant that's compatible with the existing components, such as R-134a. This usually involves adding an ester-based oil to lubricate the compressor, as the oil used with R-12 is incompatible with R-134a. A proper conversion requires flushing the system and replacing the necessary components depending on its condition.

Do not attempt to recharge an R-12 system with R-12. It's illegal and environmentally irresponsible. Find a qualified technician to perform a proper conversion to a modern, ozone-friendly refrigerant.
