Hi folks. Nice jeeps on here. I've got a 94 YJ with the 2.5 liter 4 cylinder engine. My Wrangler is a basic "S" model. I'll be soon giving my daily driver Volvo 240 wagon to my daughter to drive, so I'm going to begin driving the Wrangler daily. I live in the Washington, DC area and will need to add air conditioning so I don't sweat through my work clothes. How difficult a job is it to add an entire air conditioning unit to a YJ that doesn't have one?
Thanks,
Tom

it should not be hard but the YJs with air conditioning are hard to find (if you're thinking of getting the system from the junkyard) - if you want a new one they're not cheap but i've seen them on eBay for something like $1,200 (but don't quote me on it as this is what i remember, not sure if it is accurate or not).

Check out Vintage Air not sure about Jeeps but I know the have one for the FJ40 LC.

Hi Tom, I've got the same year/model YJ as you and also lived most of the 1970s through the 1990s in the DC-area. I know summer in DC is bad -- heat plus some evil humidity and, unless you are a tourist or student, you're probably not going to be wearing shorts or t-shirts either.
I had my no/AC 4Banger in DC for two years before I moved and I remember always bringing a couple of shirts with me on the road during the summers -- t-shirt to sweat-through when driving and then a work shirt I'd change to when I arrived. Big PIA
Getting AC installed in your 4Banger is probably the easy, though costly part (especially in light of the fact that unmodified, midly-modified YJ resale values aren't too much higher than the total of the cost of a few after-market AC kits to begin with). It's the 5-7% power (?) it pulls from the engine, when engaged, that could make driving the 4Banger even more of a hard chore.
You install AC, you might find yourself suddenly confronting some "hidden costs," as in: "I gotta do something about the way this thing drives with the AC on." So the around $700-1000+ you spend on the AC unit could double if you have to add performance parts, or do an axle gear change.
But, if you like your 4Banger ok and don't mind the cost, yeah, certainly get the AC installed. Good luck and hope it works for you :biggrin:

Vintage Air sells one. Their Jeep line has it's own domain, www.jeepair.com. AZ Mobile Air also sells one. www.ackits.com/ The only problem with these kits is that they use an aftermarket compressor. I know Vintage can supply an OEM as they sell compressors as well as the AC kit san compressor.
I'll probably be getting one of these kits sooner or later as well. It's a part of my wimpification process. :lol: It gets over 100* here in the summer for a few weeks. makes driving the Jeep unpleasant. Taking the top off is just like turning on a blowdrier in 100* temps. :finger:

ackits one is a little over $900 - that's a good deal imo. not sure if they sell incomplete kits but w/o the compressor can be even better deal (and pick one up off a TJ from a junkyard).

Jeepair.com has the same kit with the OE compressor for $900 as well. There's nothing wrong with the aftermarket compressor except it uses an additional bracket to mount the ears to the holes on the alternator bracket. I have a York so I can't have two brackets there. though.

Thanks guys. I really like my YJ and it's in good shape. Last summer we had something like 65 days over 90 degrees with over 70% humidity. It was brutal. I figure that to buy any sort of decent car for either me or my daughter to drive will cost $2,000-$3,000 and that will be something that is used and old and I won't know the history. So I figure I might as well improve the YJ for around $1,200 and I already know that it's in top shape.
I understand what you guys are saying about the power loss from the compressor. It's just something I'll have to deal with. I'm keeping my eyes out on Craigslist for an affordable 4.0 TJ with air conditioning, but I don't see one of those landing in my lap at a price I can afford.
As far as the technical side of the installation, does anyone know how difficult it will be? I can see where the compressor mounts. I presume I'll have to drill a hole in the firewall and somehow install the unit inside and under the dash. Besides that I guess I need to run some air conditioning lines, and install some new components under the hood and power the thing, but it doesn't seem all that bad to me unless I'm missing something???? I'll take it to a local garage to have the system evacuated and filled with R134.

I'm not sure if the aftermarket unit does it but I know on most modern cars the AC compressor turns off when you rev the engine up really high so you won't have any power loss. You just need to remember to turn off the AC for hills and such which wouldn't be that big a deal. I'd rather be cool and driving slow then flying up the hill and be sweating like a pig.
I would definitely buy a new OE compressor and not a used one. Both places should be able to supply one. I forget the exact model but you can find it on the jeepair.com site.
Installing one is fairly simple. You have to drill two holes though the firewall. I forget if the divots are on the firewall already or not. You basically bolt the underdash part and plug that in. Then drill the holes, add the grommets and pass the lines through. Bolt the compressor on and drill a few more holes for the condenser. You then unbolt the radiator and install the radiator. Run the lines and that's about it. Once it's installed, you can take it down to an AC shop and have the system checked for leaks and if there are none then fill it with R134.

I looked at both links you posted and ackits has the cheapest complete set for YJ 91-95 for $909 :thumb:
-
Good topic. I was thinking of doing the same for mine. I remember the first summer i got the jeep i laughed at some of those who complained about not having AC, as i was riding top down for most of the summer. Then the second summer rolled in and it was a real wet summer. I suffered through a summer where i had to have the windows zipped closed due to rain and the jeep became a sweat box. I couldnt take the top off much cause it was raining almost 2-3 times a week. This seems to be an affordable mod and i think it's worth it even if you do lose a bit of power.

i must be clicking somewhere else, i found it at $949 http://www.jeepair.com/air-conditioning/1991-1995-yj-wrangler-ac-kit-2-5-liter-engine-451.php
i'll dig some more, didn't see the one without compressor either.

I found a local guy on Craigslist that pretty much has a complete system off of a 1995. I'm not sure what he's asking for it yet. Which components (if any) do you think would make sense to buy used vs. buying a complete new kit?
Thanks,
Tom

Well, I'd be a bit worried about ALL of the seals. AC units don't like air. Also with a used kit you'll need to make sure all the controls and the high and low pressure sensors are OK. Then check the expansion valve as they are prone to failing and you don't want to have to purge the system a second time. I wouldn't trust a used compressor. If they are run while dry they will score the cylinder and leak. At minimum, I'd replace all of the seals and the compressor.

sounds like a pita to me
I'm the guy who gets the refrigerant drained and I dump the a/c parts for more power, fuel econ, and just run with the top down!! usually everyone is against me liking winter so I say deal with the heat lol

it's good to have the option, afterall if you don't turn it on won't take any power or decrease mpg, if you use it a lot then yes.
You guys got me thinking about this, would like to have one on mine as well, problem is that stock install location for the compressor is taken so i need to find a different solution.

Wouldn't be hard to run a compressor on the side like how the OBA york is done then add a V belt to the alt.

well, i have the air compressor there and the s/c mount where the stock a/c compressor goes. I am thinking that the best place would be under the P/S pump or under the alternator with it's own v-belt (the serpentine is already ridiculously long). I have a core block i can play with if i get myself to spend the money for the a/c kit I will have to come up with a mount for it.

You might think about going with an electric compressor then you'll have room.

For the OBA. Might be difficult to put an AC compressor under the PS pump. First, it's going to be awfully close to the exhaust manifold. Second the lines for the compressor will have to be long enough to clear the manifolds then get to the firewall.

you're right about exhaust, i'll have to look at how much space is there. don't want an electric oba, they suck or cost a pile of cash for a really good one. the other alternative would be under the alternator but not much room there either.

I can get the air conditioning system from a 1995 YJ for $350. I'm not sure if I should go for it or go with an entire new system. $600 is a lot of money to me, but it's not worth it if the used system is garbage.

Well that's pretty much what it boils down to. AC units as a whole are fineky and they do have problems when they get older. It's fairly common for an unused AC unit in a car to leak if not used regularly. You have to run it even in the winter so the seals get lubed and don't dry out. I think that's the biggest concern.

did you find a complete one for $600, so far $900 was the lowest one and included the compressor. I'd say $600 is a heck of a deal and it's worth over the used one at $350

I have AC on mine, and the power loss is not THAT bad. In fact, when I drive from Panama to San Jose, Costa Rica, I always do it with the AC on, and that drive, apart from being 520 miles, goes from sea level to about 3800 feet up (and considering San Jose is in a Valley, and that you have to go OVER the mountains to get here, I probably go a bit higher than that)...
-
I have also considered installing an AC system on my Yj. I like to have the top down and the doors off as much as possible during the summer, however, that does you no good when you are sitting on the interstate in stop and go traffic. The heat & humidity in the DC area is pretty brutal( I grew up in NH). If I can scrap the money together I might do that this summer.

I have the Jeep Air kit on my TJ.
We installed the parts and then took it to have the system charged.
Which was another couple hundred $$.
I had compressor problems because the guy I took it to for charging was a doofus.
Jeep Air warranteed the compressor.
You might want to add a bigger cooling fan as the ac does make the engine run warmer.

how did the guy charging it kill a compressor? that doesn't make any sense?
-
The compressor came with oil already in it. The instructions were clear on the fact that the compressor had the recommended amount of oil in it.
Doofus took it upon himself to pour the oil out and to put back what he thought was enough.
It lasted about a week. Only then did I find out what he did.
Took it to another shop to repair and that shop told me the first guy was a former employee.
He wouldn't elaborate but said there was a reason the guy wasn't working there any more.

so the compressor you have has a separate oiling system? that you can check from time to time? or is it just suppose to float around in the a/c system?
I have seen both styles. and if he drained your oil out he was a "doofus" then. because he would also run the chance of putting in the wrong oil as well.
sorry for being nosy but I had to ask lol
-
Jeep Air had actually backordered the compressor initially.
When it came, we had Doofus install it and charge it. The oil was inside it and was meant to circulate with the freon.
Although it is my understanding that the oil settles into the bottom of the compressor.

Yeah, they explicitly say do not add oil to the compressor.
Did you get the OE compressor or the universal?
-
I got the kit in 2009. I don't know which one I got, but I can say the compressor bolted right up to the existing bracket.

That' the OE compressor then. The universal uses a mounting bracket on top of the existing bracket.
-
On my 94 I had the Jeep ac put on when I bought the jeep brand new.
The places on the firewall where holes and such need put are all marked in the sheetmetal.
It only took the dealer about 2 hours to install.
Love being out wheeling in Eastern OR and being cool.
Note: the AC condenser and the power steering hoses are very close to each other.
Make sure post install they dont rub. It will crack the condenser tube.

I saw a tbi2.5l yj in the junk yard today.. even had ac.. was tempted to take the system but didn't have enough time to mess around with pulling it out. :brick:
-
I'm about to pull the trigger on this one and make the purchase. Unfortunately the Jeepair site is down :'(.
-
Reviving this thread.
I've talked to ACKits.com as well as Jeepair.com. ACKits won't sell you an OEM compressor with their kit which is unfortunate. On the other hand Jeepair will. They said internally the compressors are exactly the same. The only difference is the mounting. I don't see why they even bother using the other compressor other then to sell people the bracket unnecessarily. He said to call in to place the order to make sure they get it right.
I'm thinking about getting AC by winter. If I do then I can use the Jeep for my yearly LA road trip. I-5 without AC is a horrible experience. I'm sure once I add AC I'll be wanting to sound and heat deaden the Jeep sooner or later as well. Although I still haven't properly fixed the leak, even though it doesn't leak anymore. (ie. electrical tap across the cowl.)
-
Ac in my 95 wrangler sounds great! I have a taurus efan running on low, would this be sufficient cooling or would the higher speed be needed? Also thoughts about whether the stock radiator has enough cores for the cooling?
-

That would be dependent on how your fan is set up. AC needs air to cool the R134/R12. If it doesn't stay cool, performance drops. On a stock Jeep the fan is always running so air flow isn't a problem. With an electric fan, the fan turns off until it's needed. I have my fan setup so it turned on about 20-30 seconds after I stop.
The radiator shouldn't have any problem cooling the Jeep with the condenser on the front. It's still pretty big for the engine.
Also keep in mind that 2.5L YJ's did come with AC but it was a Dealer installed option. TJ's had it as a Factory Option.

As long as you are moving, there is more than enough airflow over the condenser to cool the AC. The taurus fan on low also is MUCH more than required. My DCC Controller would come on at 25% of low on the taurus fan when I turned the AC on (IIRC), and it woul dreally make the Jeep cold even in Panama´s hot weather.
-
Might be a dumb question but do they make any kind of portable ac unit that can run off your cig lighter or a power inverter, using my oem ac is just to much of a drag on my engine and id like to eliminate it all together, ive seen that newer hybrid cars use an elecrict compressor. Wonder how hard it would be to use one of those instead of a belt driven one

the reason hybrid cars are using an electric compressor is that the engine is not spinning all the time, power consumption for an equivalent cooling capacity would be the same so you won't gain anything.
EDIT: as far as a cigarette lighter goes, you still need all components for an a/c including a condenser, evaporator compressor and all the hoses so you won't find a compact enough unit to just plug it in your cig lighter.
-
I know a guy who uses a water mister that works by pumping up a bottle with air pressure (by hand) and an electric fan run off the cig lighter. Works pretty well for wheeling in the desert.

I don't think it will be a problem with my fan setup since my fan normally turns on no more then 20-30 seconds after I come to a stop. It turns off immediately after I get moving again.

Well, I got my system ordered. Using a new OEM compressor with Jeepair's kit. Supposed to be here by sometime next week.

How hard is it to add air conditioning?
Step one. Remove soft top or hard top.
Step two. Drive really really fast!!!
Hope that caused a laugh.

Yeah, everyone says that... Then you find out they have another car for their daily drive.
When temps hit 100+ or humidity hits over 40% and you want to get somewhere without looking like you wore your clothes in the shower, you're SOL.

Well, out of the two vehicles I have, my jeep is the cooler one to drive in. My Honda has no AC and it seems more closed quarters then the Jeep. In my Honda I just gotta swap the clutch off the AC and a new one in. To add AC to a Jeep, I wonder if that is more work then it is worth?
-
I went to Rockauto.com and found that some of the parts are interchangable like the AC compressor. Around here it is 25.00 for a used AC compressor from the yard. That right there could save you 200-350. Depending on a few of the other parts and if they can be reused or not may save you more. Just a thought.

It's not a good idea to buy a used compressor from an unknown vehicle. If the system has been dry and the compressor was turned on the seals could be gone. If you want a leak free system go with new parts. Otherwise you'll be spending a lot of time looking for leaks and having the whole system purged and then refilled. Or having to top off the system every year.

Yes, A/C will work with a soft top on.

Yes, A/C will work with a soft top on.
Not as good as it will on a hard top, though; less insulation on the top and a lot more drafts coming in...

Jeep sold and sells AC with the soft top still. Yeah, you're going to lose a lot of the cool air because of the thin top but I don't think it will be that bad. At least not with sail cloth. Denim is a bit thin but again, as long as it's blowing it will help.

I'm not saying it wont work (I used to run mine with the AC and soft top in Miami), but it's just better with the hard top...

Jeffy,
Did you get the kit yet? did you install it.

Jeffy,

No, I'm still waiting on it. I think they build the kits to order so the lines have to be custom cut for the compressor I want.
-
a writeup would be nice :wall:
not sure if i'll ever get to install one in mine but it is on my wishlist.
-
Well, I still don't have it. Actually there was a delay as they're waiting for more compressors and brackets. I had to talk with them to get my order sorted though. I didn't want the kit they offered since the compressor has tabs and uses an additional bracket. I wanted a OEM compressor so I can reuse my OBA. Took two days of emails back and forth to get this all sorted but I think it's gonna happen. Unfortunately they don't have the OE compressor either. They said they will email me when they do get it.
Supposedly, they said a rival when out of business and they have been sacked. Not sure who that is. ACKits.com and Collin Brothers both sell Jeep kits still. Actually ACKits now has a 10% off sale.

Years later I finally ordered the air conditioning kit from Jeepair. Price was $949. I'll report back how the installation goes. My daughter is driving my trusty Volvo 240 wagon that has air conditioning, so now I'm in the 1994 Wrangler full time. I can't take a Washington, DC summer in the Jeep in my work clothes without air conditioning!
Wish me luck.

I have a Vintage Air AC on my 1997 TJ with a soft top. I rarely use it, but when I do it works great. I was not the one that installed it, I bought this way. Mines an older model that uses a seperate small blue button (AC stamped on it) to engage the compressor. This thing is slow to begin with so performance wise I really don't complain. If you want some pic, send me PM and I will send you a few.

I worked on the Jeep on Saturday and Sunday. I've probably got about 10 hours into the project so far and I'm about half way done. It was a pain working under the dash to get the fan box and evaporator with the vents installed inside the Jeep. But that part is all done except for a couple of electrical wires that I need to hook up that are the last step. The stupid blower fan housing got in the way of the gas pedal, so I had to cut some of the gas pedal lever off at the very top. It would pivot forward when the gas pedal was pushed and get stopped. I was upside down a lot on Saturday. It took way longer than it should have to get that unit installed under the dash.
Sunday I mounted the compressor and also the drier. The next step is to remove the radiator and then install the condensor in front of it. Since the radiator is original to the car I figured I might as well put a new one in since the old one could spring a leak any time. 18 years is pretty good for a radiator to last. I'm going to also install a new water pump, thermostat, and hoses while I'm in there. The new water pump does not look quite like the one on the YJ, so hopefully the parts guy gave me the correct one.
After that stuff is installed, the only thing left to do is run the hoses. I've already cut two holes in the fire wall and put in rubber grommets. So hopefully running the hoses will go easy. Once the electrical connections are made, I can take it to a shop to get evacuated and charged with freon. It's been an ok project so far, but I was getting sick of being upside down for about 6 hours under the dash.
-
I still haven't finished mine yet. I screwed up my shoulder so I'm waiting. I've got all the hardware for the compressor now though. Unlike the kits I'm using a OEM compressor so there is no additional bracket to deal with. I also had to get yet another serp. belt. My Jeeps run 4 different lengths over the years. I have issues with the condenser though. The line fittings are too close the the radiator. To get the evaporator install, I actually had to trim the bracket it's on so it's not putting unnecessary pressure on the ducts. I think that was the hardest part though. Part of the delays for me is that I'm using the stock compressor and have to deal with OBA at the same time. So I've got to source hard to find hardware which wasn't that hard but took an extra week.

The new serpentine belt will require the addition of a idler pulley below and to the right of the alternator.
-
One of the problems I found which make it harder to mount the evaporator was that the metal L bracket was being pressed down because of the duct controls. This causes the whole thing to want to rotate up which makes pushing the motor back in there harder. I ended up trimming the bracket so it wasn't an L in the middle and it helped a lot. Otherwise the L bracket is forced to flatten out.
If I didn't have OBA, installing the AC kit would have been a breeze since I wouldn't have to source other parts. Not to mention, I have to buy a hose crimper since my kit is more DIY because I bought it without the compressor.
-
Yup, getting the evaporator unit under the dash was more difficult than it should have been. I'm not quite sure where to hook up the electrical connections, but I guess I'll figure that out.
With the holiday this weekend, I should be able to get everything installed and ready. After that I'll have to work out a time to drop it off at a local shop to get evacuated and charged with 134a.
I'll take more photos as the installation progresses.
-
Last night I verified that the water pump I picked up from Advance Auto Parts was correct for the Jeep and is reverse flow. I also spent a little time looking at the AC lines and figuring out where they go. If I'm bored tonight, I might try to run a couple of them.
Looks like this weekend I'll be able to complete the rest of the work.

For the electrical, you can run the power off a fuse tap. I think you'll need to make an extension cable that will go from the plug at the switch, through the firewall and to the pressure switch. It's been a while since I looked but I think that's how it goes.
When routing your lines make sure everything is lined up to where you want it. Once the system is charged your SOL if you need to change any angles.
-
keep in mind that you need power from a +12v RUN position on the keyswitch, not a CRANK/RUN +12v or a permanent +12v.
-
I really want to do this as my next project. I was hoping to do it this year, but the engine rebuild set me back.

what do your instructions say? does the kit come with a relay that goes to 12v permanent and has a switched 12v command wire? (you might need to add this yourself if not).
I can look tonight in the YJ FSM to see which fuse to use (i'm a poet :lol:), what year is yours? (i have the '94 and '95 copies, nothing earlier and i think they changed the harness in 92 or 93, it's mainly the same

Keep in mind that even thought it's a kit, there is a lot of tinkering involved.

All you need to do is find a Key'ed +12V. It's not a big deal. The source must stay on when the key is ON and turn off when the key is OFF. If you wire it to a permanently ON it will just mean that you will need to turn off the AC when you take the key out. It's not a big deal. I'd use the Radio or 12v Cigarette Lighter circuit.
-
For some reason my cigarette lighter is not working now that I have relocated it under the evaporator unit. I need to figure that out to see if it can be an easy point to run the air conditioning.
I'll resume work on the air conditioning system tonight. I'll replace the water pump and radiator as my first step. Then move on to the condensor unit and ac hoses.

The job would have been a lot quicker if I did not do a new radiator, water pump, thermostat, and hoses. But it is well worth it. All that equipment was original and 18 years old. Now I should have years of trouble free/leak free cooling.
For the air conditioner system I still need to run the two AC hoses that go from the evaporator to the compressor and the dryer. Then I need to do a ground wire, wire to the dryer, and a wire to the compressor.
I should be ready to take it to a shop to pull a vacuum and charge the system next week.

So when you bolted up teh radiator did you just squish the AC lines at the condenser?
-
No need. The AC lines for the condenser were low and on the right side and they are clear of the radiator. The lines are flexible so you can bend them easily if you want, but mine were fine.
-
I'm probably going to do this for my 1.9TDI swap as HPA says all the jeep's equipment will fit (including AC) and run as before. SO, i need to save some cash if I'm going to be able to do it. What is the cheapest rout to go in order to get AC in there? I was thinking about getting some junk yard parts and then new parts from Jeepair. What parts can I "trust" from the junkyard and what parts should I def buy new? Jeffy mentioned def getting the condensor new (i think i read that) what else should I buy new and what can i just get from a yard?
-
I didn't want to trust used or junk parts, so I went with an all new system.
I guess in theory, if the evaporator/fan unit under the dash is good that would save you some money. A used condenser might work. Probably used lines would be fine. Certainly a used idler pulley will be fine.
At a minimum, I'd to with a new compressor, new o-rings for the lines, and a new dryer.
-

I mean the connectors actually.
You can see the upper line is right against the radiator. I think unless you were going to connect the hose after putting the radiator in, you wouldn't notice.

Jeffy,
In that one photo you can see that I connected the AC lines to the condenser unit before installing the condenser into the car. It looked like it might be a tight fit to do it afterwards.

Yeah, that's what I thought. Just squish it all in there. I don't think the OEM is like that though. I had a friend send me some pics. It's jsut one of the thing you run into and ask yourself why. Makes it impossible to remove the hoses unless you pull the radiator, if you were going to fix it.

This is hard to see, but the white wire connects to an empty fuse spot on the fuse block under the dash on the driver's side. There is an empty fuse space that only puts out 12 volts when the ignition is on. A spade connector fits in nicely.

My work is done. I need to drop it off at a local shop to have them pull a vacuum and charge with 1.5 pounds of R134a.
Thanks for viewing.
When I tested out the fan I was very excited how powerful it was. On the lowest fan speed it blew out a TON of air! I think I will be very comfortable with this system. I'll report back later this week once it's going.
I need to adjust the serpentine belt because it gives a chirp on start up.

UM your in Canada...you can't live without AC for the 4 or 5 days it might be hot? :stick:
Nice job Dan. I am sure you will be enjoying this. I am curious as to how this will effect the felt horsepower when it's running.
-
Looks good. Was there a need to remove the battery box? Or was that so you could get the lines in easier? I've been sick as a dog for the past week and wasn't able to make any progress over the long weekend. I still need to buy a crimper though. I have to build the hoses still. Mine didn't come pre-made. I was also looking at the drain for the AC. I hate the idea of having to drill another hole through the body. Haven't decided on what I want to do with that just yet.
Was all od the connections done dry? No teflon tape or anything? I'd guess the O-ring would be enough.

you can't use teflon tape on those... well you can on the thread but it won't do anything since that part is not sealing
-
I used teflon tape to seal that heater tube pipe that comes off the water pump.
The AC lines are done dry with only the o-ring. I retrofitted my Volvo 240's AC system a few years back to convert it to R134a and all the AC lines on it are done the same way, just o-rings.
Removing the battery tray is easy and didn't take long at all. Removing the battery tray makes access to the fire wall very easy for the AC lines. What worked for me was to to first install the rubber grommets into the fire wall holes. Then I lubricated the grommets and AC lines with some liquid dishwashing soap. I then pushed the AC line fittings through the grommets. This required me to bring the AC lines up vertically along the firewall, so the battery tray would have been in the way for that.
You might not need to do it that way if you need to crimp the ends of the AC lines to put on the fittings. You might be able to slide the AC lines straight through the grommets and then after the two lines are inside the cabin, you could crimp the ends. I guess you need to figure out what is going to be easier for you.
I made sure to use a rubber grommet for the AC drain line hole too. I guess now that I'm done, I could spray some undercoating around where the drain tube comes out underneath the jeep.
-
@DanMarino - were your hoses crimped already
@Jeffy - somehow i remember your lines were not crimped, is that correct?
-
Yes, my AC hoses were ready to go.
-
Did you run the purple compressor wire through the firewall on the dr side?
-
Yes, there was a dimpled area to the right of the top of the gas pedal. So I drilled through it and put a grommet in there to protect the wire. I ran the wire up and along the back of the engine with the rest of the wire harness and over to the compressor and dryer. The wiring was very easy once I located the 12 volt spot on the fuse block that is only powered when the ignition is on. I also drilled a hole in the fire wall to attach the ground wire with a screw.
-
I usually send wires through an extra hole in the big grommet that the throttle cable passes through. I've had all my wiring go there there over the years. There is also a useful ground above the throttle pedal. There's a screw holding one of the cables for the HVAC that works nicely. Keeps from having to drill new holes.
-
Yes, my AC hoses were ready to go.

Got the system evacuated and then 1.5 pounds of R134A installed. The system works great. Air temp is 39 or 40 degrees coming out of the vents at idle in my garage. The shop was only a couple of miles away from my house, so I didn't get a good feel yet for how much power the AC system robs from the 4 angry squirrels. I'm going to love the system this summer.

Get well Jeffy.
I'm loving the cold air. This thing is freezing me out. I'm having to turn it off because it is so cold and the fan is so powerful even on the lowest setting.
I have not yet driven on the interstate with the AC on. Around my normal suburban driving, the only time I notice any power loss is when driving up a very steep hill. Moderate hills I don't notice any power loss. It does not seem like a big deal to me though. I'm finding that I am down shifting a little sooner, but I would be down shifting on the big hills anyways without the AC on.
The positives seem to overwhelmingly outweigh the negatives. In certain climates I believe this is a great feature to have on any Wrangler.

I think on the highway, you'd break even if you ran an electric fan instead of that clutch fan. The only problem would be to either wire in a bypass or else set the electric thermostat low enough to kick the fan on closer to idle temp. Otherwise, the AC will get warmer when you stop, until the fan kicks in. you could also run an AUX electric fan that only turns on when the AC is on like on most cars.
-
My 1992 Volvo 240 has the clutch fan attached to the water pump, but it also has an electric fan that comes on when the AC is turned on. Yes, the electric fan does improve the AC performance when stopped at a light.
I doubt I'll do any modifications to the Jeep's AC system now that it is installed. The AC perfomance is outstanding. I also now have the confidence to work on the system down the road should repairs be needed. Maybe one day I'll look into getting a vacuum pump.

what I'm saying is to replace the clutch fan for n electric fan. Depending on how you want to go bout it, you could either wire the electric fan to turn on when the AC is on or add an additional fan. This would take the load of the clutch fan off the engine and help offset the performance loss. It as not thing to do with the AC itself.

I drove on Interstate 70 from Baltimore, past Frederick, MD and back in the Jeep. Air temperature was in the mid-80's, so I had the AC running. The Jeep performed pretty much just as it always does on the interstate. I stayed in the right hand lane and ran the 65 mph speed limit with no troubles. The Jeep did not like going up the mountain just west of Frederick with the AC on, and it hated going up that hill prior to the AC installation. I did notice that the high pressure AC hose that went into the evaporator/fan box from the fire wall had a lot of condensation on it. So yesterday evening I wrapped some pipe insulation on it. I'm 100% satisfied with this project.
Best wishes to all who followed my work.

Hey, did your drier come with a U bracket or the plate attached to it? I'm getting ready to install mine but I haven't figured out if the drier is supposed ot be clamped to the fender or clamped into the bracket.

The new AC system on the Jeep is ineffective when it is 103 degrees outside. It works well up to about 95 degrees. When stopped a traffic lights the temperature of air blowing gets warmer. It seems to do much better when moving along at 40 mph or more though.
I did notice the compressor short cycling off and on when it was not performing well in the 103 degrees. I wonder what causes that to happen?

I know there's http://autorefrigerants.com/. For DC area summer heat, I'd probably consider charging the system with (iirc) ES-12A

Hmm, I don't think the compressor is supposed to cycle. The only thing that turns it off would be low pressure at the dryer. I also wonder if the stock fan is really able to pull enough air though the radiator and condenser. That would explain why it works better when moving. When you're moving the Jeep shouldn't really need the fan at all. Is the Jeep overheating? Maybe your fan clutch is bad. So a spin check on the fan.
-
AC systems like air moving across the condensor, sitting at a light idling probably spikes the pressure and most likely it has a high pressure switch that cuts out the clutch when the pressure gets to high. an electric fan wired in to the ac wiring will help best way is to either run it when ever the ac is on. Or get fancy and plumb a pressure switch in so when the pressure goes high it kicks the fan on
-
I'm not sure how to check the clutch fan attached to the water pump.
The pressure switch sensing high pressure sounds logical. It is only short cycling on very hot conditions. Early morning, reasonably hot days, or evenings I'm getting frozen out in this thing and the compressor is not short cycling.
My Volvo 240 has an electric fan that comes on whenever the AC is turned on.
Since I installed a brand new water pump, thermostat, and radiator when I installed the AC system, the Jeep is not overheating.
I'll have to go to the junkyard and look into an electric fan I guess. Any suggestions for a donor vehicle that would have a fan that might fit well? Is the idea to remove the clutch fan and install an electric one only?

I'll have to go to the junkyard and look into an electric fan I guess. Any suggestions for a donor vehicle that would have a fan that might fit well? Is the idea to remove the clutch fan and install an electric one only?
Spin the fan by hand. Does it spin? It shouldn't be locked up nor should it speed freely. There should be some resistance which will let the fan rotate maybe 1/4 turn at most.
Have you considered emailing Joe/Jeepair and ask his opinion? He's been great helping me sort out my mess.
If you want to get a salvaged fan check out the Lincoln MKVIII fan. These are nice and big. Make sure to get a two-speed fan. These fans are overkill even on lo-speed. I know the stock fan is adequate but it wasn't designed to be used with AC. The 2.5L's fan is smaller then the 4.0L's.

Jeffy, is the fan on the right from a 4.0 or from a Lincoln?
Maybe I can hit the junkyard this Saturday?

No that's a 4.0L fan. Do a search on Taurus or Lincoln MK VII fan. There are a few od us running them.

I contacted Jeepair and they suggested checking out the fan clutch. My fan seems to spin way too easily from what I can tell. Jeepair thought that the fan not locking at low speeds would the a likely cause, especially since I'm getting great cooling when moving.

That's what I was thinking as well. The fan shouldn't rotate more then 1/4 turn with a good push. The clutch is fairly inexpensive and easy to replace.

Ordered a new fan clutch from Advance Autoparts for something like $35. I'll pick it up today and report back about if it makes a difference.

Installed the new fan clutch. The new one certainly spins less freely. I'll run it for a week or so until I experience some hot weather in stop and go traffic.

98 degrees in Washington, DC today. On the way home from work the AC compressor did not short cycle. Everything nice and cool inside the jeep. The system seems to be working great.

Here's a trick for getting that #10 hose with the grommet into the place without a huge hassle. Push the grommet to the end of the hose and over the crimped end but not over the nut. This allows you to squish the grommet into place. Then lube up the hose with some windex or whatever and push it through. Saves a lot of time fumbling, trying to squish the grommet though with the hose going though it.

That's good news.

Are you still satisfied with the system? I am seriously thinking about pulling the trigger and picking up one of these systems

I drove on Interstate 70 from Baltimore, past Frederick, MD and back in the Jeep. Air temperature was in the mid-80's, so I had the AC running. The Jeep performed pretty much just as it always does on the interstate. I stayed in the right hand lane and ran the 65 mph speed limit with no troubles. The Jeep did not like going up the mountain just west of Frederick with the AC on, and it hated going up that hill prior to the AC installation. I did notice that the high pressure AC hose that went into the evaporator/fan box from the fire wall had a lot of condensation on it. So yesterday evening I wrapped some pipe insulation on it. I'm 100% satisfied with this project.
Best wishes to all who followed my work.
I don't think any 4 banger jeep likes going up those hills, not at interstate speeds anyway.
