1989 Trans Am GTA R12 to R134A Conversion - Third Gen Camaro and Firebird Conversion

[@av8tor1908]

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.

[@michaelm3381]

Good video. The AC has blown hot air in my 1998 Firebird for years, but I just suffer through.

[@RamblinGarage]

Easy fix and relatively cheap.. you can use my gauges!

[@williamodonnell7053]

It's 2 valves bro easy fix

[@RamblinGarage]

@@williamodonnell7053 a little more if you want it to work well, but easy nonetheless.

Bad ass car 😏

[@RamblinGarage]

Sure beats a Chrysler 200 amirite

@@RamblinGarage damnnn 😂

[@afr946]

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

[@RamblinGarage]

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.

[@Aerozona23]

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?

[@RamblinGarage]

There's calculations for it, I had to search on the third gen pages

[@Berniessen]

Did u keep the old R12 oil in?

[@RamblinGarage]

@@Berniessen no, cleaned the lines out and replaced with r134 and pag.

[@Berniessen]

@@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).

[@aztekaamusiik]

You put in 4 cans of R134a

[@RamblinGarage]

@@aztekaamusiik 39.2 Oz, you have to go by weight, not necessarily can numbers.

[@aztekaamusiik]

@@RamblinGarage im literally put in in tha cans so far ive put 2, 250ml cans

[@aztekaamusiik]

And nothing its still blowing hot air out

[@RamblinGarage]

@aztekaamusiik I think you have a ways to go yet, is the compressor kicking on yet?

[@aztekaamusiik]

@@RamblinGarage yes

[@oldskool1979]

R134A is crap on old cars.. too high pressures causes leaks ! R12 much colder and less pressure !

[@RamblinGarage]

That's why you replace o-rings and valves :) R12 isn't much colder if at all to 134a.

[@ericheld4382]

R12 and R 134a pressures are almost the same.

[@Heve62]

Its the size of the r134a molecyle that can escape through a smaller hole that causes the leak with r12 orings
