I have a 95 4runner and am selling my A/C system

i was wondering if anybody can tell me how to release the freon, if there is a special way.. but the book says have a shop do it, but i dont want to do that

any help would be greatly appreciated
thanks

Why do you want to lose it? It wont work with out it...unless you are going to convert to R-134a. You should put a vacume on the lines so the new stuff will go in easier. There is a high side and a low side. Do some googling. haha.

Go to youtube, type in davidsfarm and look for a video by him called "ac repair"

Getting a shop to release the freon will cost you a couple dollars. That's it.

i really cant take it to the shop since there is no motor in it, but pretty much i just wanna know what i have to do to remove the ac system, like any special tools or anything.. i dont know if i have to relieve the freon or not, but if i can get the system out without doing that then that would be cool

PlugItIn

its gona be a little work to get all those lines and everything off. Theres a lot of little hoses and lines that are a joy to get loose and then off. You wont be able to get it all out with the freon in it...freon is supposedly bad for the environment so you dont just want to dump it in the atmosphere.

Its actually illegal to dump Freon (r12) into the environment, and carries a hefty fine.

R134a is NOT "freon", it is a refridgerant. They claim its environmentally safe. I would still not suggest venting it, but I believe you can do so without any repercussions.

desert-rat660

your system should be r134a

PlugItIn

thats what i was thinking...if you want to vent it, just undo a hose from the condenser or the compressor, or push down the little check valve...as long as its 134...

mickeycrack18

or you can take a valve core extractor to the low side if its r12. they did a study and they found theres nothing that harms the ozone in that stuff. it was just propaganda bs to get ppl to by their product and not theres. or if you want to find an old truck tube and just get a transfer hose there like 3 dollers and fill it up

Who is they? Do you have links or proof?

I know that at our wrecking yard, we are regulated by the EPA and its a very big no no to vent R12. It is indeed very harmful to the environment.

You could look around make sure no ones looking and cut the line...But as stated above it is illegal.

PlugItIn

He cant cut it, cause he's trying to sell it...Click on me for some more info on R12

Edit...Look under the hood for a sticker or on the AC compressor, it should be 134A...if it is, use a valve stem tool as stated above or just undo a hose...

Then why WOULD you even say it? Its illegal for a really, REALLY good reason. This stuff literally eats away the ozone layer, that invisible thing that prevents the sun's rays from cooking us all.

Take it to a shop or call a certified AC mechanic. Hell, with the fact that r12 is so hard to get these days when I did a conversion they took it for free. Its worth a lot of money.

If you dump it straight into the air, you are no better than ANY other loser mechanic that just dumps his oil or coolant in the yard or street. You give US all a BAD name!!!!!

Bobzombie

if its r12 then an evac ac machine is the ONLY way it shopuld be done. If it is r134a then you can simply loosen one of the lines any where on the ac system and wiggle line until it starts leaking. Watch your eyes as there is pag oil in there and it is under pressure.

YOTA_FORCE

GVOLCRunner....Stop the crying..I wasnt saying he should do it. If you want to freakin complain and cry about the world go to another forum. Of course he should take it in and dispose of it properly. But hes going to do what he wants.

turborich

just vent it out of one of the fittings. It's really no big deal & nobody will ever know.

Matt16

Good post. You may think its just a little bit, but that stuff is SERIOUSLY potent. There has been a large measurable positive effect in high arctic ozone after CFCs were phased out of most applications.

No ozone= prevalence of skin cancer rises. You know the lead blanket they place over your nuts during an x-ray? Ozone= lead blanket. It only makes a very small fraction of the atmosphere, so very little of it in the first place.

Matt16

Stop giving out crap advice. "No one will ever know"... do you also steal if you don't think you'll get caught? No one likely will ever know if you steal a handful of nuts and bolts, or mix in a few extra boards from a lumber yard. People who follow those words of advice are leeches on society. Two thumbs down.

dude calm down on him. jesus. dont jump up his arse cuz he asks a question.
actually, if you break down the chemical of both r12 and r134, they are basically the same thing, but 134 uses different oil, which is what screws up a r12 system. also, the patent on r12 ran out, so they brought out 134. when that patent starts to run out, they will come out with a R256 and say 134 is bad for the atmosphere.
also, r12 works slightly better than 134, it gets colder faster.
but for a POLITE answer, i wouldnt discharge it urself unless u know FOR SURE that its 134. or, as stated, its a hefty fine if ur caught.

Matt16

The OP asked a legitimate question as it appears he didn't know that R12 was.

"Turborich" may be a good guy, who knows, but the comment made is so typical of short sighted people who figure because they didn't immediately get cancer or change the climate when he vented his AC that it doesn't affect the environment in which we live (no, I don't mean Amazon rainforests or somewhere removed).

Its the idea that you can get away with it because you're one person and one person won't have any effect. BIG problem with that is that if everyone thought like that, life would be pretty ****ty. In effect you're taking advantage of society. That's where I'm raising objection,
