Do you need to replace the compressor on a R12?
You should replace the compressor of your old vehicle with a new and powerful compressor as R134a uses high pressure due to its larger sized molecules as compared to the R12. So simply filling the old compressor with the new refrigerant will not make things work out as they should, and you will face performance issues.
When did cars start using R12 instead of R134a?
Many organizations believe that R134A contributes to global warming. Vehicles manufactured before 1994 used R12 for air conditioning. Vehicles older than 1994 started using R134A instead of R12. So what if you have a car that was made in 1994 or even earlier?
