Re: How To: Install A/C air conditioning in a 92-95 Civic
This thread rules. You guys have started to turn my fantasy of installing A/C in to my '93 CX into a reality. Well, you guys and Pick 'n Pull, who will apparently sell me a complete A/C system for $100! 
My question now is, what A/C systems will actually fit in my car? I know that the 94-95 Civic A/C is preferred over the 92-93, but it sounds like I can also yank parts from the Del Sol? What years? What about Integras, Accords, CR-Vs, …? I can check Pick 'n Pull's inventory online before I head down there, so I can see when appropriate cars hit the yard, but I'd like to know what all of my options are when searching.

Great write-up! This forum continues to deliver, you guys are the best of the best in my eyes! Can't wait to install a/c in my 95 DX.
P.s. I find it amazing how many people think the previous owner took the A/C out.

Re: How To: Install A/C air conditioning in a 92-95 Civic
So I am installing AC in my 92 hatch VX and I have all the parts necessary, including the climate control with the AC button. I have read in this thread a few times that the AC button is required. This is obvious, but can the button simply be removed from the AC climate control and be 'popped' into the old one (current one in car withou AC)? That way I don't have to pull the climate control assembly out of my current car. If so, how can this be done? Thanks for any input. I just did not read/see this aspect in the thread while reading it. I apologize if I overlooked it.

Just curious, I see that a different crank pulley is needed. Do they make one that has just alternator belt and AC compressor belt ribs on them and not the power steering?

A different crank pulley? No, that is not needed. But to answer your question, a crank pulley does exist without the power steering belt section on a vehicle that didn't have power steering.

Man, you are quick! I apologize about the question. Again, my memory was serving me incorrectly as I sit away from my car.

I think this is a much better question. Do you recommend using the OEM dryer or simply a generic brand one from the auto parts store? I usually run OEM, but the price difference is about $50 and wasn't sure if it was worth it on such a part.

I've been reading this post for a min now and I am about to attempt to install A/C into my 93 civic cx...today I just picked up everything A/C off a 95 civic ex so hopefully it goes all good...so I guess it looks like I have to switch out that 3 wire plug and O-rings..everything else i'll let the shop do the vac, drain, a/c fill etc..wish me luck

Grab the evap box out of a CRV or the latter 6th gen Civic. They have provisions for a cabin air filter that blocks all the crap from clogging up the evap. The EKs very rarely have the filter or filter frame, but it looks like the CRV got them standard.
Depending on which you get, you may have to wire up the three wire thermostat vs the EG's two, but it's very simple. All three wire colors match up to your stock wiring in that harness in front of the evap box.

Re: How To: Install A/C air conditioning in a 92-95 Civic
EVERYTHING will fit in 92-95 Honda Civic all models. I promise you, I have tried ALL of it. Only thing you need to make sure is...if you use a R12(92,93) AC unit then it must be ALL R12. If you use R134a(94,95) then it must ALL be R134a. Both R12 and R134a will fit in any year and model car, it's just they will not fit with each other. The thermostat that has different harness under the glove box is removeable. Example. If you have a 92 or 93 civic and it has only a 2 plug harness; then you can remove a thermostat off a 92 or 93 R12 AC system and use it for an R134a AC system or 94, 95 Civics. Vise versa.
Make sure to flush the system with AC flush fluid. You cannot flush through the compressor or drier. The evaporator requires you to remove the valve in order to flush. I do not recommend any other fluid beside AC flush fluid. I also recommend if you are using R134a to flush the compressor with PAG 46 oil and refill back to spec with PAG 46 oil afterwards. R12 Ac compressor requires different oil, so make sure you have the correct oil for the correct compressor. If you are using R12 AC system use ONLY R12 freon. If you are using R134a AC system then use ONLY R134a freon. Before charging the system make sure you evacuate the system. Meaning; you have to vacuumn the AC system to at least -25psi(30psi is perfect vacumm). Leave it there for atleast 30 min. to make sure you have no leak and to boil off any excess fluid that might still be in your lines.
I recommend putting R134a AC system in all models Civics. Because the freon bottles are a lot easier to find and a lot cheaper. The R134a is a lot easier to work with also due to most of the R12 parts and items are off the market due to not being so enviromentally friendly. So having said his; reminder if you are going to use a R134a then make sure you take a thermostat off a 92, 93 ONLY IF you have a 92, 93 Civic. If you have a 94, 95 Civic then get 100% R134a.
Things you need:
Compressor - can be found under power steering
Belt w/ tensioner - near compressor
Low side AC hose - Bigger hose connecting compressor to evaporator
High side AC hose - Smaller hose connecting compressor to condensor to drier to evaporator
Drier - Near/next to where you fill up your windshield wipers fluid
Condensor - Next to radiator (condensor is on driver side)
Evaporator w/ theromostat - Behind glove box
Ac wireharness. - Starts from passenger headlight/airbox area, goes between radiator and bumper all the way to driver side headlight.
AC button. - On center console.
This could be very confusing at first so good luck. If you guys have any questions feel free to email me anytime at mikenguyen85@hotmail.com I will be glad to help you out. I once was mind boggle about all these AC **** until I had to learn the hard way and now I would like to help anyone so they do not needto go through what I went through for a cold car cabin.

I second this. I just swapped over all my parts from r12 to r134. Not fun. But well worth it.

so whatever that is on the crv or ek evap box..i can use it on my eg evap box?
I just noticed when I took off this 95 civic evap box..it had a bunch of leaves in there..so if I get that crv or ek evap box..whatever that is on there will help not get any leaves in there?

Re: How To: Install A/C air conditioning in a 92-95 Civic
Was working on a friend's 95 EX and realized that it uses a three wire thermostat. So apparently it's the mid generation change, 92-93 with R12 have the two wire, and 94-95 have the three wire just like the EKs and CRV.
In any case, it's easy to wire the three wire to a 92-93 since it's color for color and they're all there in the harness.
da9bigboi too late to answer your question but you swap in the entire CRV or EK evaporator and box. It bolts up, lines hook up (R134a) and you then have a slot for a cabin filter. If you get an EK box, you need to get a cabin filter frame but all CRVs have the frame and filter included. Either way you have to order a new filter on amazon because none of the parts stores carry it.

Re: How To: Install A/C air conditioning in a 92-95 Civic
damn I didn't know the ek or crv bolts right up..i prob would have done that...
ok today I finally got the belt on and took it in to get service and hey..it worked..it blows cold but not cold enuff...I bought a temp gauge and its at 70 when its like 100 degrees outside...shouldn't it be colder like around 60 or less?..i have a 93 civic cx d15b8 slow engine with black leather gsr seats front and back...I wonder if changing the 3 pin to 2 pin thermostat changed anything on the evap box making it less cool...but it does keep me cool..no sweating..since replacing all parts I didn't buy anything new on the lines, compressor, dryer..all came from a ex civic coupe with 200,xxx miles..only thing new is a ac belt...I too wonder if changing the dryer or cleaning the condenser will make it cooler too..

Re: How To: Install A/C air conditioning in a 92-95 Civic
There's really just one way it all goes in to the vehicle. You need everything from the 134a or R12 system. No mixing or matching. Everything is plug and play with maybe the exception of the thermostat in the cab behind the glove box. There are details on that in this thread as well. I just hooked up the box with the in cab air filter and its associated thermostat to my old 92 (that unit comes from about a 98). Just look at the wiring diagrams and it is simple. Blue/Red seemed to be the constant, then hook up black/yellow to the black yellow in the harness that runs by it (need to solder all these) and then finally the third color will hook up to the other and only color left in the 2 pin plug (92/93 versions).
You NEED a new dryer. That is likely a large reason why yours doesn't work as well as it should. As soon as you expose the dryer to atmosphere then you should get a new one. They are pretty cheap. Hopefully you replaced all the o-rings with AC rated orings as well.
