No, there is retrofitting required.
It's only Freon if it was manufactured by DuPont, but to the important things... Your 89 would have had an R12 system from the factory. You can't use R134a in an R12 system unless you do at least a partial retrofit (evacuate all the R12 and compressor oil, replace the orifice tube, replace the accumulator, replace the hose connections, add PAG oil and R134a).
An R12 system must be retrofitted to be made compatible with R-134a.
No, you should not mix R134a and R12 refrigerants in a 1993 Buick LeSabre or any other vehicle. Mixing these refrigerants can lead to system damage and reduced efficiency, as they have different chemical properties and pressure requirements. If you need to convert from R12 to R134a, it's essential to properly evacuate the system and replace any necessary components to ensure compatibility. Always consult a professional for refrigerant conversions.
No. It is illegal, will not work properly and R12 Freon is not available for the public to buy anyway.
No, you should not mix R134a with R12 refrigerant. They are different chemical compounds with distinct properties, and mixing them can lead to system inefficiencies, damage, or even system failure. Additionally, the oil used in R12 systems is incompatible with R134a, which can cause further issues. It is essential to properly evacuate the system and use the correct refrigerant for optimal performance and safety.
To convert a 1990 Miata's air conditioner from R12 to R134a, first, you need to recover and properly dispose of any remaining R12 refrigerant in the system. Next, replace the receiver-drier and any O-rings with R134a-compatible versions to prevent leaks. Then, evacuate the system to remove moisture and contaminants, and finally, recharge it with R134a refrigerant, typically using approximately 75% of the original R12 charge. It's advisable to have this process done by a professional to ensure proper handling and system performance.
