Just had to fix mine so I know. It uses R12. I had to replace my compressor so I had it modified to134a.

No, but it will effect the heater. The only fluid that will effect the AC will be your refrigerant known as R-134a
Don't confuse engine coolant and air conditioning refrigerant. Engine coolant is Dex cool- Do not use any other kind as the sensors in the system will read differently with the wrong coolant and make incorrect adjustments in your system. Air conditioning refrigerant in your car is R-134a.
Hfc-134a is the refrigerant used in moble air conditioning systems (MVAC).
Standard R-134a coolant will damage an R-22 coolant system because they are chemically different. They also have different characteristics for pressure and freezing point.
Refrigerant R-134a.
