In the course of this replacement it is also recommended to flush the air-conditioning system. In addition, the mineral oil of the R12 system is to be replaced with PAG or PAO oil. All components should be checked for function and damage.

In the course of conversion, the system must be checked for leak tightness. R134a was and is used as replacement refrigerant besides several 'drop-in' refrigerants (refrigerant mixtures).Д®ven today, the conversion from R12 to R134a is still an ongoing topic in the area of classic and modern classic cars as well as in several non-EU countries. Ever since then, R12 systems had to be converted during maintenance or repair work. 2001 marked the official final end of R12 in vehicle air-conditioning systems. There are still numerous vehicles on the market with air-conditioning systems originally designed for refrigerant R12.
