Thanks all of you for the help ive joined the army and im shiping out on the 26th I wanted to fix my ac before I left but that may not happen becuase I didnt know what I was getting into, but thank you for the loads of help! :-) I really appreciate it

 

I hate to say it but you totally screwed yourself by putting r-134a in there, suck that **** out immediately!

It's not compatible with the old R-12 oil and r-134a and old r-12 oil turns into acid...not a weak acid, but a strong one.

You can recharge your old R-12 system with no issues with r-152a... also known as computer duster

It actually works. I have it in my car.

 

I didnt put r134a I put an r12 equivalent in from a recharge kit

 

Joe....let me be the first, on this thread, to thank You for willing to service OUR GREAT COUNTRY in the Armed Forces....I am a pilot...got bounced around job to job...had a chance to go in (to the Army) as an officer, but they couldn't promise me a flight training slot....so, I went back to flying...then looked at it again..( a few years later) and I was too old...LOL....

THANK YOU SIR.

 

oh Yea, keep ur head down!!!!!

 

+1 on JJs advice. This is why you need to replace the dryer and completely evacuate
the system before adding anything. I've done the 152A on 3 different vehicles and
it works great. My 2000 BMW 323i blows colder now that it ever did in 2000. Add the
needed oil back into the system as liquid in the dryer and the compressor then
seal it up and fill with coolant.

 

Sorry for stepping on the OP thread, but this topic is really hitting home for me and I wasn't sure what to do; wanted to confirm folks' guidance here....

Air conditioning in my 85 FB GSL has gradually been petering out in cooling ability, and I'm pretty sure it's the charge...I've read all the warnings about using stuff other than R12 (which I believe is not legal anymore??)--but wasn't clear on whether there was a direct replacement.

So, sounds like 152A can be used as a direct replacement? No ruining the AC?

I'm a little reluctant to undertake this myself; is this something a shop can do for me? Or is it a pretty easy thing to do?

Again, sorry for jumping in, hope folks can clarify.

Thanks!

 

No shop will mess with 152a as it's not a standard refrigerant. Easy to do if you get the right tools and do some reading.

 

Has anyone used RS-24?

It's advertised as a drop-in replacement, but didn't find any references on the board.
