What happens if you put 134A in an R12 system?
What happens if you put 134A in an R12 system? R134a systems work at higher discharge-side pressures than R12 systems, which could lead to compressor seals leaks. Additionally, since R134a is composed of much smaller molecules, it has a greater chance of leaking from an R12 system. Can you convert R12 to R134a? Before 1995 most vehicles came with R12 refrigerant in the air-conditioning system. If your air conditioning is no longer cooling as well as it once did, then chances are you need to recharge the refrigerant in the system. Instead you can convert an R12 system to an...
