Equipment needed to self-service R134a air conditioner
Hey all -
I'm anticipating having to open up my air conditioning system on my '85 Corolla because there is a leak and I don't want to have to keep taking this thing into the shop to have it serviced. I already planned on getting an electric vacuum pump and a manifold gauge set. What else would I need to empty the refrigerant and oil, flush, vacuum, and refill? I am using R134a, the car has been retrofitted with fittings and o-rings. THanks James |

Probably best to see if a shop will reclaim and use your refrigerant for free. If the system is now empty it sounds like your list will get you by. You might want to get some UV sensitive dye and a blacklight.

Will dumping my refrigerant into the atmosphere get enough out to safely put a vacuum on it anyway? Won't there still be oil in the system? And is it important to have the system flushed out? > You might want to get some UV sensitive dye and a blacklight. > > Don > www.donsautomotive.com > > Thanks Don.
