Best way to convert to r134a?

[erehemantresni]

Anyone have any experience with this. I usually just take the whole unit out but with my current car I need it since I will be moving farther south. THanks.

bring it to a mechanic so they can flush it and shit, that's what I did... the conversion and charge was like $70... well worth it to me

Talk to Spaz. He is a certified A/C tech, and was (is?) going to do a writeup.

the easiest way is to just fill it with freeze 12 its like r12 but i guess its safer for the ozone but it doesnt get as cold as r12 but not as cold

i don't know where you get it as in british columbia, its iilegal to sell "top up cans" which that would be, generally i'd never use them, because it is never pure r12 or pure r134a, they mix it with other gases to pass epa regualtions. and another reason i would never use them is becuase lost contains propane....and well any mess up around the lines that creats a spark....boom....good bye car....and good bye life possible.

imo double check the contains before using top up can's.....which i wouldn't use in teh first place.

i just got my system recharged yesterday with R12.. cost me 200 bucks :shock:

the dude made is sound like converting to r134 would be more expensive, hardware wise... and that it would not get as cold as the R12.. he seemed like he knew what he was talking about, but you never know...

i'd be interested in seeing the 'how to'...stop drinking all that beer and get on it!!! 8)

In some cases you need to change alot of stuff, like hoses, the compressor and drier for it to function perfectly.
Before I knew anything about a/c, I replaced my leaking condensor, pulled a vacuum and just charged it with 134a, without changing the dryer or measuring the refrigrant. That was over a year ago and the a/c blows cold on the highway and when the temp is below 85 around town.
But in traffic, when its over 90, it doesn't work too well.

You can still get R12, we use it all the time in my shop. It's about $30 for 12oz, you'll probably need 3 cans. It may be more cost effective to have a shop charge it with 12, rather than pay for a drier.

im in ca so freeze 12 can be bought at any parts store in a can or 30lb bottle

Funny thead.
I have a 1990 325iS and just today i got my old system AC filled with the DURACOOL cans u guys mentioned, and it works like a charm. Two cans, and 40$cdn later, my AC was blowingpretty damn cold. I just hpe that the system itself doesn't have any leaks/mulfuctions I do not currently know about.... Definitely worth it to me... ;)
