what specifically makes one system the R12 vs. r13 system? compressor, dryer, lines etc?
Here are the parts I have from the 95 del/civic
big foam covered hard lines,
under dash unit.
92-93 parts,
drier (need a new one anway so I can get the 95)
harness (only differnece was the positioning of 2 wires which were repinned)
compressor
evaporator (other radiator looking thing)
fan
smaller hard lines. </TD></TR></TABLE>
Both R12 and R134a has same components. Such as: compressor, drier, low lines, high lines, condenser, evaporator, harness. They will not work with each other. I stress to say again that R12 AC SYSTEM WILL ONLY FIT AND WORK WITH OTHER R12 PARTS. and R134A WILL ONLY FIT AND WORK WITH OTHER R134A PARTS. That being said kwest10, your evaporator will fit in your car fine, the big foam cover lines you are talking about is your low side line, that will fit from the evaporator fine. BUT it will not fit your compressor at all. It will be too big. If you want to keep your evaporator and low side lines than you must get a compressor, condenser, drier, and high side lines off a Civic 94-95. That to me will cost more, what I recommend is you keep your compressor, condenser, high side lines and trade/sell your evaporator and low side lines for 94-95 version. Also remember you state you are going to get a drier off a 95, so remember to do that also. Also to answer your questions, all the parts for 92-95 Civics will only work on 92-95 Civics, maybe Del sol. But for any other cars such as 88-91 Civics, 96-00 Civics, Integras will have their own AC unit. All cars 93 and older will use a R12 AC system and is recommend to use R12 if any of you are planning to install one for your car. Cars made 94 or newer will use R134a and is recommended to R134a. It is not that confusing, plain and simple, if you do not want a head ache, then what ever model and year car you have, only use parts coming from that exact model and year.
BOTH R12 and R134a to my opinion will work fine. They do not use R12 in most cars anymore due to the fact that it's very bad for the ozone layer. R134a is somewhat friendlier. Some may say R12 is much colder but to my honest opinion, done right, they both will deliver cold air. I have done cars with R12 and R134a and I have both gotten them down to low 40F, high 35F. To me, that is cold enough on a hot hot day. I mean, if you want to go pure numbers and see how low you can get it, then that's your project, but a 35-40F cabin is what most cars will produce coming off the factory floor.

Hmm, no updates on the forum maker on how his AC is going. Maybe I should rip mine apart and show you guys a complete how to. Who needs it? Let's take a vote, if there is a lot of people wanting AC, I'll do it. I have everything already so I should have the write up done in a few days.

Re: (lv6l)
I wouldn't mind seeing a complete DIY on an A/C install. I just got most of my A/C parts and it'd be nice just to know where they all exactly go. You have my vote.

Seems like not much people is doing AC. But if you like you can PM me when you do your AC and I can help you through. AC is a tricky process that people always under estimate.

Update: I've had to order a new dryer. I ordered one already but it was for a 94. There is a difference in the dryers from 92-93 and 94-95, and the fitting with the sight glass doesn't fit. So anyway...I'm hold for a new dryer.

A/C is working!!!!!!!!!! OMGZORZ!!!!!!!!!!!!
Ok, make sure you get the correct dryer. That's the first thing. The dryers are different from 92-93 and 94-95. They are both the correct overall OD but have different sized inlet and outlet holes. Whichever hole has the sight glass on it is the one that is different (the hole in the middle).
Anyway, once you connect everything you're basically good to go. Make sure that at this point you hand off your system to a professional. Making sure the system is moisture free, leak free, charging it, and monitoring the system after it is complete is critical. Thankfully my dad did commercial A/C for 18 years, so he took care of everything. Drawing a vacuum on it took 3 different oil changes in the vacuum pump due to how much moisture was in the system. Now why was there moisture in the system? Because the guy I bought it from left it outside without any plugs in it. When you leave it outside without any plugs in it you can introduce debris and moisture into the lines. I spent over 8 hours cleaning each individual line, compressor, condenser, etc, and there was still enough moisture in the lines to warrant changing the oil in the vacuum pump twice.
Anyway, after the dryer is installed just make sure that you charge the system up with approximately 2 cans of r134a from your local automotive store. Make sure you rev the engine after you have charged the system. Don't add any more refrigerant if you haven't rev'd the motor. Once you've rev'd and held the motor, check the level / amount again. However, having said that, you won't have to worry about it if you have a professional take care of it.
All the wiring behind the dash worked out just fine. It works so good that I can't leave it on all-the-way cold or it gets too cold. I LOVE IT!!

Re: (Electrodynamic)
Great thread. When it comes to used parts for an A/C installation (or for part replacement), what is the recommended way for cleaning out the lines, compressor, dryer, etc. prior to install?

Re: How To: Install A/C air conditioning in a 92-95 Civic (honda.lioness)
honda.lioness. . . . are you saying that you spliced the black/yellow wire from the new plug into the black/yellow wire that heads to the recirculation plug?
Thanks.
Thanks.

Oh yeah man same here. Its 130 degrees when I get into my car to go to work. I need A/C bad haha. Since this is my first Honda, I really am clueless about putting it back in. Only if I had someone to show me the way and we'll this thread seems to fit the bill!

Hi! I have air condition in my vehicle and I'm planning on removing. We don't use that much of a/c in Canada since it always cold here. Just wondering if move the a/c would need to move the belt from the compressor.. I'm not too certain sure.. Help..

Re: How To: Install A/C air conditioning in a 92-95 Civic
Its best (for me) to install the evaporator 1st and feed the hose thru the fire wall in the engine bay. There is a plag to remove on the engine bay side of the fire wall.

Re: How To: Install A/C air conditioning in a 92-95 Civic
does it just go through the fire wall & just sit there? or what?
can you send me a picture of where it goes plugged in on the
engine bay side please!
