I know this is probably the wrong forum, but I didn't know where to post this. I have an 85 IROC and I wanted to know what type of freon it originally used.

Thanks.

 

R12.

 

i got mine charded today, using r34, i recomend u using r34 my uncle does repairs on a/cs, got mine working today, cost me under 20 bucks if everything is working properly, if urs isnt workin at the momemnt, check your clutch on your compresster, if it moves then ur compressor clutch is good which is often out on thirdgens, then take it from there, hope this helps

 

ya it works, just wasn't cold anymore. I don't think its ever been charged. Thanks guys.

 

Yeah, switch your R-12 over to R-134 if you can. R-12 is sooooo damn expensive. Mine needs charging and it's still R-12, so eventually I'm just going to switch over. I hear it's not too hard of a process to do yourself.

 

R-12 is colder than R-134A I hear. But I hear 'ya. R-12 is getting expensive!

 

If you can get 12 and you system doesn't leak just top it off with 12. The cost of a proper conversion to 134 will be MORE than what 12 will cost, plus you'll still get snow from the ducts as opposed to 134 which takes longer to get cold even in a vehicle designed for it. If you are down a pound you may be only talking $60 bucks or so for a fill.

 

u all may say im stupid or something, but hell, u dont need the kit to swith over to r134, its just a waist of money to tell u the truth, my uncle is a mechanic and has worked on a/c's his whole life, and he says that u dont even need the kit, so he done mine, without the kit, and its colder than my moms brand new s10, so u all take it fromt here, if u dont believe me, then try for yourself, and if u think im wrong, prove me wrong, if u can,

 

I really wouldn't want to prove you wrong if that's the case.

 

I'm not worried about the cost of R12. Where I'm going, I don't have to pay for it. Its not what you know, its who you know.

 

Well in that case, lemme tag along with you and get some of that free stuff.

 

As long as you don't mind the drive. I'm about 30 miles south of DC.
