Our cars originally used R 12 refrigerants and are non exsistant correct? From researching, the R12s are bad for the environment and that the R134a is the one out there in stores avaliable. I understand that you need an adaptor (retrofit) on the factory port.
Do I need to remove the old R12 stuff out of the AC system in order to add R134a refrigerant? Can both R12 and R134a be compatiable in the AC system?
Btw the coolness in the car is not completely drained. But I feel its not as cool as it was before.
not compatible. i believe there are refill kits available that are r12 compatible though. look into that. may not need to convert.
however, if the system is low, it indicates a leak and should be looked at. especially with r12
I just spent a half hour in studying and reading this^. Its too complicated for my brain and I’m actually a mechanically inclined kind of person. I understand that basically you’ll have to convert your valves to fit r134. Easy. I now how to remove parts and such like the “drier” . but It got too technical after that.
There were some links to videos that made it easier to understand. That’s really just a DYI, but good info in general on what you need to replace to have a good working system.
Eric the car guy on you tube helped alot. yeah the videos make them more understandable. Thanks. Now I got to buy that “manifold gauge” and a vacuum from harbor freight tools.
Question: in the beginning of the Eric video, he mentioned to perform the evacuation of the freon before you start the steps in this video. I couldn’t find the link of evacuating the AC system. Can you send the link? thanks.

Obviously not everyone is going to want to go buy gauges and things like that. At least if you decide to take it to a shop, you can be semi knowledgeable about what needs to be done and what they are telling you is wrong after watching and reading all that. I’m not sure on evac to be honest. I was going to have a shop do that part.
absolute truth… initially I was going to take this on myself, but after seeing hom much ot would cost me to do it, and adding to the fact that my car didn’t have the best working AC to boot when I bought it. I now know what it should costy and can add 1 hour labor to the cost of parts…
it is pretty straightforward, but after totalling up the cost for tools and equipment I will likely only use 1 time it probably wouldn’t set me back so bad to just have my mechanic do it, and be able to know it was done correctly and to standard. After that I have no problem recharging on my own…
