- 1989 Trans Am GTA R12 to R134A Conversion - Third Gen Camaro and Firebird Conversion
Showing how to convert from R12 to R134A in our 1989 Trans Am GTA. This process should be similar, if not the same, for all third gens and similar vehicles of their generation.
For this particular vehicle, you will need 8oz of PAG oil and 39.2 ounces of 134A. Note that some compressors come pre-filled with PAG oil.

Been looking for info on how to do this for a long time. Thanks to you, my GTA is blowing cold A/C again and I couldn’t be happier with the result. Thanks for posting stuff like this, sure appreciate it.
Awesome, glad to hear! I had a valve go bad shortly after this video, I need to fix it unfortunately.
Good video. The AC has blown hot air in my 1998 Firebird for years, but I just suffer through.
Easy fix and relatively cheap.. you can use my gauges!
It's 2 valves bro easy fix
@@williamodonnell7053 a little more if you want it to work well, but easy nonetheless.
Bad ass car 😏
Sure beats a Chrysler 200 amirite
@@RamblinGarage damnnn 😂
Did you have to put any inserts on the suction line that goes to the compressor? Getting a leak from there were the green o ring is at
I'm not sure I know which fitting you're referring to. I did have a valve give out on the high pressure side, so I need to get that swapped out this year.
where did you find the specification for how much r134a to put in and how much oil to put in? when you buy the compressor does it tell you?
There's calculations for it, I had to search on the third gen pages
Did u keep the old R12 oil in?
@@Berniessen no, cleaned the lines out and replaced with r134 and pag.
@@RamblinGarage perfectly done thats how u shut convert ure AC.
I am thinking of recharging my car with R12,meaning i have a 1984 GM car with the huge Harrison A6 compressor that stil has pressure,even the car is parked in a barn for several years,i will take it out next month,replace the tires fluids fuel and vaccuum the system and put R12 in it.(i was super lucky i got my hands on a big new 13 14kg cylinder).
You put in 4 cans of R134a
@@aztekaamusiik 39.2 Oz, you have to go by weight, not necessarily can numbers.
@@RamblinGarage im literally put in in tha cans so far ive put 2, 250ml cans
And nothing its still blowing hot air out
@aztekaamusiik I think you have a ways to go yet, is the compressor kicking on yet?
@@RamblinGarage yes
R134A is crap on old cars.. too high pressures causes leaks ! R12 much colder and less pressure !
That's why you replace o-rings and valves :) R12 isn't much colder if at all to 134a.
R12 and R 134a pressures are almost the same.
Its the size of the r134a molecyle that can escape through a smaller hole that causes the leak with r12 orings
