my car currently with the engine in it...does not have AC, however. the new motor that i'm putting in has an AC compressor on it already. but my Q's is...is it worth going with AC in the car? if so what parts do i need to get to get AC installed and working order.

what motor? and how extensively was it removed on your current car? Or did the car never have it?

damn dude that will be alot of work..... you can have all my old a/c stuff if i can find it all! youll have to tear your dash out and run some wiring and lines.. not sure about anything else

I've got the complete system sitting in my garage. It's not really that difficult to install. The only hard part might be some wiring under the dash but I'm not sure what's all involved there. JADKAR put his in recently so maybe he can tell you exactly what needs to be done with wiring under the dash. Where are you located?

well i have till summer time to figure this all out. so i have time!

i had to take my dash out to get all the a/c parts out, it wouldnt be too bad if you had it apart

Maybe I missed something then b/c I only had to remove the glove box to get to the condensor. What else is there?

well you could do it like that, i had my dash out all ready, donig something else

OK guys here's the REAL deal. I bought my car new 1990 and I didn't opt for AC. Once I decided I wanted it in 1993 all the OEM kits in the US were long gone so I just dealt with it. Now that I'm doing an extensive rebuild (and I'm an old man) I decided I want to stay cool.

Here's what you need to install AC in your CRX if it was never there before.

• Used AC system from a "reputable" source. Best bet would be a member on-line you know & trust. The kit needs the following
  • AC evaporator (behind the glove box)
  • All AC lines (there's a lot of them)
  • Receiver dryer (I bought a new one, they're cheap)
  • AC condenser
  • AC Compressor (the one that comes with the AC kit should be used)
  • AC wiring harness (there's only one harness and it will have all the relays attached)
  • AC button on the climate control
  • AC fan (it should come with the kit, you may need a slim one, see below)
  • If you want to be slick and OEM, you will most likely need to buy all the brackets and grommets to secure the lines and what not to the car (I did this and it makes it look totally OEM)

Some notes:
The dash DOESN'T need to come out. The way the dealer installed it is by taking only the glove box out. You have plenty of room to install the evaporator. All you do is take out the "dummy" duct and then bolt the evaporator back in where the duct was. The evaporator has three fittings on it that poke through the firewall. The holes in the firewall are already there, just remove the grommets. 2 are for the AC lines, and the 3rd is for the evaporator "water drain" tube. The wiring harness has it's own hole in the firewall and it gets snaked into the evaporator vicinity. it's plugs into the evaporator housing and also into the main harness via a plug that's hidden under the carpeting. That's it for wiring, no need to splice anything into the climate controller, the cars are already pre-wired!!! The only other thing in the car you need to do is pop off the "dummy" button and plug the new AC button in.

Now under the hood. Pull the tie-bar off the car unbolt the radiator top brackets. Move the radiator back a little and drop the AC condenser in front of the radiator. There's already brackets in the car to accept the condenser (as long as you got a CRX kit). Mount the receiver dryer, it goes next to your washer tank. Run all the AC lines mount them with the brackets you should have bought. The hardest thing is going to be getting the AC compressor to fit with your engine. There are several brackets on the market and it's going to depend on your engine and your choice of compressors. For me I bought a JDMSh!t AC bracket for use with a CRX compressor and a B series block. Mount that bitch up and connect the lines to it. The fan is the next hardest thing. If you have a big after market radiator, or header you are most likely going to have a huge space issue. You are not going to be able to get that clunky OEM fan in between the header and the radiator. Your best bet is to do what I did, get a "slim-line" fan and try to squeeze that in there. If it still doesn't fit (mine didn't) wire the fan as a pusher, take you bumper off and put it in front of the AC condenser If you do that make sure you get a small 6" or 8" fan. Finally the rest of the wiring needs to be snaked along the engine compartment and connected to the fuse box, compressor, pressure switch, and AC fan.

I maybe leaving some things out but you get the idea. It's really not that hard. I thought the hardest task was sourcing the correct AC parts and hoping they came undamaged. For me, I had to replace 4 lines because the were busted. I charged my system and tested it (in January) and it seemed fine. Compressor kicks on, AC fan kicks in as well. Cold dry air came out of the vents. However, it was Winter so I need to check again when it gets warmer.

I will be posting photos to this thread and detailing some more steps when I get more time.

Hope this helps

The dryer should be replaced any time the AC system is opened, so definitely get a new one. Don't try to cut costs and use the one that's with the rest of it, because any water in the system will result in acid that will cause you problems down the line.

When I bought my 91 HF, the previous owner had stripped out the back and all the HVAC in the car. I really would like to get ac back in my car but could never find anyone who was selling there ac components. Any ideas on where I could find an ac setup?

For those of you doing your own ac install remember if your going to charge your system yourself you can get the refrigerant in a kit from wal-mart. Make sure before you install the compressor you add about 1 to 2 ounces of pag oil forthe 134-a system. Be sure to add about the same amount to the dryer. Once everything is installed youll need to pull a good vacuum on the system to get all the air out of the system before charging. Once vacuum has been pulled for about 20 minutes let it stand and check your vacuum gages to ensure there are no vacuum leaks. If there are no leaks prceed adding refrigerant to factory specs. Now most will tell you the amount of pag oil i told you to use is to much, that is correct but remember when pulling the vacuum youll lose about half of your pag oil into the vacuum and the lines this is ok. There will still be enough in the system to operate it safely. Another helpful hint anytime you do ac work or open a line always replace your orifice tube, this is like a screen that will catch any debree that might be in your system failure to change this will deffenitly result in ac failure, when the orifice gets stopped up the pressures in the lines get to high and it will automaticaly cut the ac compressor off before it blows lines or the compressor. Oh i almost forgot after adding the oil to the compressor turn it over slowly by hand to allow the oil to circulate through the compressor.

Nice I never knew that, good thing I dont do my own AC work. Never had to remove one Doesnt sound to fun

*~edit~* I take that back I have once. In the supra. heh oops
