Help with R134 Convertion

[kraziebaby158]

I plan on converting my S13 (1992) to R134a. What would I need to buy to to do so? And how would I do it? I know alittle about woring on cars, but never did anything with the a/c. I would really appreciate the help and suggestions.

what is a r134a? you mean s13.4(s13 coupe with s14 kouki front)?

He might mean a s13/R34 conversion?

you guys are tards. he's talking about the A/C refrigerant.

Found this link that might help you out, but it's not 240SX specific. It's a program that tells you how to do the conversion.
You have to purchase it though.

I think he's talking about the fuild the AC uses.

I don't know whats involved, but you can still get the older stuff at select few shops. You just gotta look at the right places.

Edit: Damnit, Jimmy beat me to it

haha, i failed.

First you need to find out what type of System you have, (maybe it was changed over from the previous owner, Mine was) Look on the low pressure side (before the compressor) and look for a "hook up port" if its a threaded shreader valve then you have an R12 system if its a Quick disconect fitting then its R134A.

but you should take it to an A/C shop so they can replace the seals, Filter Drier, and the low pressure line, pull a vacuum and fill with refrigerant and oil.

So really a shop should take care of it, Unless you can do it yourself

Some autoparts stores sell a kit, i remember when i worked at advance they had one for 3x.xx dollars. Comes with fittings, book, and dvd i think.

lol.. i literally thought palmface too after i read those first two posts.

anyways, you may want to check to see if using r134a refigerant will mess up your rubber seals and whatever else because i read a thread about some FD guys discussing converting refigerant, but it was mentioned that the system wasn't made for it, and it will fuck up the compressor/or seals.

i guess its sort of like using ps fluid in your ps pump for s13/s14 when you're suppose to use atf.

take it to a shop. Best bet. Releasing refrisgerant into the air is illegal and just not cool. There are too many holes in the ozone already.

Im not a green party vegan pussy, Im just saying.

And yeah those 2 first posts after the OP... Classic. R134a?
But yeah you can still buy R12 places if you look. I know my shop has about 10 cans of it left.

Wow Instant comedy......!!!!!!

This thread made me laugh so hard. Not to be a jackass or anything but the replies and the spelling pushed a little shit out of me. No offense. Thanks for making my stressful shitty day do a 180. Nuff Respect.

I have a can of R12 refrigerant that I got from a friend of my dad. From what he told me, the stuff can't be bought anymore so there's not much of it left. If I had the stuff to refill it I would do it for you if you were local but, you're not local and I need the tools.

[Silverbullet]

i have nothing to contribute to this thread except LOL at the first 2 posts !!

[MyLevinGTZ]

you can have it drained and do the majority of the work yourself if you feel so inclined. you'll have to pull the whole system out and flush it with some oil (spirits), replace the seals between all the connections with 134a safe ones, and the evap canister. i'd even go as far to say you should rebuild the compressor (seals) too.

134 has a much smaller moleculular structure and will escape from the R12 system much easier. R134a also uses a different oil for lubrication and must have the old system completely cleaned of R12 oil.

once the system is all hooked back up, take it to an AC shop and have them put vacuum to the system to make sure it's holding pressure and have them charge it too. if done right, it shouldn't cost THAT much. just a pain to get out some of the AC components and clean them out.

good luck. if you are unsure, better to pay a shop the $300+ to do it. some shops around here are actually buying the R12 from people doing conversions too, something to look into if your system is still charged.

u forgot to tell him not to have his ac system open for a long time to the outside or the drier will soak up with moisture soo... make sure u cap off the system when putting all ur stuff back together. The drier dont cost much but having to buy a new one still sucks.

[kraziebaby158]

First of all thanks to all of you that helped, hopefully I can do it myself without any problems. Second I am a girl! Lastly I cant believe the first two posts either...it's hilarious!
Again thanks for all the help.

its actually not that bad to do a retrofit system its pretty cheap too, but ive only done retrofits on old acuras, hondas and some nissans...the retrofits were less than 100$...if you lived in cali id do the retrofit for cheaper than shop cost since it really isnt that hard and i have the license to do it haha
