Hey guys, here is a little update to questions I constantly see about AC units and choices.

Back in September, after one of the hottest damned summers I can remember, I decided to get AC.

I looked at the Cool Cruisers unit, and the Vintage Air unit. Both were about the same price and both have extensive write ups on how to install them. Some where along the line i got to Old Air's website, and started looking around, the Hurricane unit looked to be nice and have similair dimensions, but after searching here on Mud, and not finding any installs, and only more questions, I decided to go with the Vintage Air unit, mostly because everyone says that the Cool Cruisers unit, only cools the passengers knees.

So I ordered the unit, and got inside of a week, the dealer I delt with is a member here on mud, and was extremely helpful! It could not have been easier.

I got all of the under hood stuff done; new bracket, compressor, condesor, drier, and hoses.

Then I mocked up the evaporator which had the all the vents in it....

I cannot tell how much I hated how this looked!!!

I even left it in for a few days to see if it would grow on me....it did not.

A few days later, I read a thread on here, https://forum.ih8mud.com/40-55-series-tech/516170-vintage-air-buyer-beware.html , and that just lowered my spirits and expectations.

So what to do? I left all the under hood stuff there and put back in the stock heater box, as fall and winter were on their way. Over Christmas I was talking with my Brother and my Dad, telling them about how I really had nowhere to go on the project. During that conversation I was saying how I just wanted something that was very stock looking and similair in size. My Brother reminded me that I had already sent him a couple of emails with links, to Old Air, in those emails, I had already measured out the stock heater box location, and the measurements were pretty darned close to stock....

February rolls around and I call Old Air, they were incredibly polite and helpful, I told them of my situation, and the salesman, Clint I think, suggested that I just get one of their "Inside Packages", as I already had everything else.... sounds pretty good.

I drove up to Old Air, as they are just down the road. In the showroom, they had all their units there, and looking good. I was talking to Clint, and I said, I was concerned because I had no way to be sure if this would fit or look good... He said, no problem, we have a mock unit, the Hurricane Air blower and evaporator casing with none of the innards. OK, we walked out to the cruiser and held it up as well as we could, I still had the stock heater box in place.

It looked good, damned good, to my eyes anyway.
I bought the unit, the 2000 series- for smooth firewall installations, and picked it up a week later.

This weekend I finally got to it.
I did not want to drill into the Firewall, so I used a bracket, just some 16 gauge 2 inch flat straping. The Hurricane Air unit, has 3 holes in the back to mount it, 2 holes on the top, and one on the bottom. These holes are off center to the passenger side.
The brackets the unit comes with are flimsy and useless.

This was the most difficult part, I mounted the strapping to the 2 top holes, I had to use a 1/8 inch spacer dues to the design of the unit, or else it would not have sat flat against the firewall. With these spacers I only had enough room to slide in my box end wrench, to tighten the strapping and the unit to the firewall. I only used to two top holes, and it is held on tight.
In hindsight- I would just drill through the firewall.

Like so many of us, I run my stereo in my center console, this left a huge gapping hole, where the stock radio should be. I waited for along time for an original cover to show up, but never found one I liked, or thought was priced fairly. So I was thinking I would go to the junkyard and see if there were any vents that I could stuff in there. That all changed as I was taking the stock heater box out, I noticed that the vent on it was just screwed in, so I took it off, and held it up, wow, pretty close.. The width was perfect, but it was a little tall.... but not enough so that is looked bad or out of place.. to my eyes anyway...

The vent tubes all went in with ease. I had some 1 1/4 black crush tube lying around, so I used this to go to my side defrost vents. I just spliced it into the the defrost tube, and sealed everything up with back duct tape.

The switches were hands down the easiest part. The switches they provide you with are the same size and shape as our pre-existing holes for the "Fresh Pull" knob, so the have that flat portion on the bottom. The fan switch and the thermostat switch are both "Rotary Style", Booo!! I could not find a 3 speed fan switch that was "Pull style"....Since the new fan switch was in the exast same place as the old fan switch, I just used the same switched power source, by adding a spade connector and plugging it in.

The fan Blows like a champ!! Much more power than my stock fan-- to be fair, my stock heater needed to have all the foam replaced..
But here is the really great part, the windsheild defrost and the side defrost vents blow with an incredible amount of force!!! The two vents I have on the side blow very well and the middle vent blows very well too. I was concerned that since the middle vent is set, and cannot have the direction of airflow adjusted, it would be irritating or useless, boy was I wrong. It is perfectly aimed at my chest/shoulder/face.

Tommorow I am taking it to an AC shop to have the system vaccumed dry and then charged up, AC lines cut and cripmed to length, etc.

As the look of the unit goes, I think it looks amazing!! It is pretty close to stock size, and I have no issues with the shifters, I am running the stock 4spd and transfer case, so the H55f, may be a differnt story.

I cant think of anything else, I will report back, once the actual AC is set up and rolling.

Feel free to ask any questions.

Now time for some pics....

One thing I forgot, the unit has two setting of air folw, operated by a pull cable, Defrost and The Front vents. Halfway out will have both operating. Mechanical and feels just like the stock pull knobs, so less things to go wrong.

I used another "Warm Pull" knob installed under the dash to control that.
Works perfectly.
 
Good info & write up. Very interested.

Will be looking forward to how well it cools.

Thanks, John
 
Thanks for the writeup. I have been debating this upgrade for a while. Nice to see it clears a stock transmission shifter.

I too am looking forward to the reports of how well it cools.

Nice touch with the vent cover from the old heater box. I may go that route as I used to have my CD deck in that location and now just have the empty hole.

Looks nice.
Do you have any photos of where you cut the firewall to run the 4 heater and A/C hoses--was the back of the engine in the way?
Any tips on running all those airduct hoses behind the dash over and around the switches and gauges?

Thanks !

Bear-

I did not do any cutting, there are 3 different models of the Hurricane unit. 2 models, the 1000 and 300 series , have their hose outlets directly out the back. The 2000 series has its hose outlets out the side. However I was thinking like you, in that I was concerned If I drilled through the firewall, the engine would be in the way. But I don not think this is so, since from inside the cab I could see where other mounting bolts were coming in, and they were easily accessible from under the hood.
--- This is part of the "under the hood stuff", that I used from "Vintage Air" unit. With that set up, you remove the stock blower motor, and they supply you with a cheap-o plastic cover. You are supposed to route the AC lines and the heater hoses, through the holes in the cheap-o plastic cover, 4 holes for 4 hoses.

The position I have the Hurricane Unit in, allows me to use the stock hole for the Heater Hoses. I went to Ace Hardware and bought a sheet of 16 gauge sheet metal, and traced the cheap-o plastic cover and then cut it out, and drilled 2 large holes (1" 1/4) for the 2 AC lines. Then I cut the slots for the bolt holes for that plate, this gave me alot of wiggle room, as I have never worked with metal and do not know how to repair it...

As for the ducting hose, I forgot to metion this, Everything up there is tight!!! It is not stuffed in there, and it all looks fine and functions well, but it is tight... The ducting comes close to the stock switches; the hazards, wipers, but it does not interfere with anything. The temprature switch has two wires ( one from the fan switch and the other to the bianary saftey switch under the hood), theses two wire stick out far and actually come into contact with the far right duct.

The wiring is so simple... well it seems simple. I have literally had to hook up a total of 4 wires. 1- wire to a switched power source, I used the already exisiting power source for the stock fan switch. 2- the wire from the thermostat switch, to the bianary safety switch inder the hood. 3- the safety wire from the compressor to the bianry safety switch. 4- the ground for the blower motor in the cab. No pics of the hoses, right now, if I remember I will snap a few tomorrow.

After looking at the Old Air website some more, there are only 2 things I see as a benefit in the Vintage Air package.
1- The AC compressor/Alternator Bracket; it is a solid chunck of steel that is well thought out. I only had a problem with the spacers they provided, they were too big, I had to grind them both down.
2- The "Cheap-o" plastic cover that goes over the hole through the firewall.
Other than that- I cannot possible see a reason why anyone would go with their unit.
I have read that everyone seems to be disappointed in the cooling level or ability of their units. So if everything is "mediocre", why not go with a unit that most closely resembles the stock setup and location.

I have heard that Old Air is the company that makes the Cool Cruisers unit.

I know that TLC Icon, uses the Hurrican Air unit, the 1000 or 3000 series.
 
Thats right Sean, I knew someone had done this unit before, I even tried to look for your thread to post a link.

So, there are even more options for an install method.

Here's hoping this unit will be able to keep me cool all summer long in the Texas heat....
 
Would love to hear how you like it after you run it for awhile...nice job thanks...
 
Hi!

Nice write-up, and an install that looks factory, thumbs up!

Have you left out floor vents? While a/c might not be necessary here in Denmark, keeping your feet warm in winter is!

(not to mention ours are 24V...)
 
Well that depends...

The Vintage Air unit, is designed for the FJ40, their compressor/alternator bracket was designed for the 2F motor. So with the Old Air unit you will need to do some custom work. The other option is to buy the bracket from Vintage Air, then everything else should be relatively straight forward. I would think this would, or any custom bracket work you have done, would increase the total cost of the unit.

The Vintage is somewhere around 1200, and the Old Air unit is just over 1000 (full package, I got the "inside package" which is about half the price).

Of course I still have to get a price quote for the refridgerant, and drying the system, etc. I will report back the total cost...

Cristian-

I did leave out some sort of floor vents for two reasons,

1) On the drivers side of the Hurricane Air unit it has a small flat slot that acts as a blower vent. It is on whether or not you have the vents set to defrost or front vents, and even in between.

2) Not really a concern here in Texas.

I did however kick this idea around, as most modern cars do have a setting for you feet. The idea I came up with was to purchase a "Y" split for the defrost duct tubing, Old Air has one on their website, and it has a hand control that allows you to switch from one vent to the other, or in between to have airflow to both.

But this would have lead to more ducting, finding a place to put that hand adjuster. This was just a little too much, as I have said before, everything is tight up there, and at that point I would have been just stuffing duct tubing under the dash. But it may be worth it to you, over yonder in Denmark. Here in Texas, You can deal with a crappy heater, but most of us would rather die than live without AC.

PS- Did you get your side window defroster vents installed?
 
Hi Richard

Thanks for the reply!

Here in DK a seperate heater running on diesel or gas is much more a convienience IMOP :-)

Yeah, I got them in, made a crap job cutting the holes in the dash, but that serves me right for skimping on tools, the (cup drill?) was low quality and didn't make a clean cut. But the ducts cover it, so I'm happy, now I can almost see my mirrors :-)
 
Ok, got her back and just took her for a 2 hour test drive.

I am very happy with how well it cools.
But it was about 70 degrees outside...
So the real test will be when it starts to get really hot.

There were no leaks or issue with overheating as well, I had the blower motor on high and thermostat as cold as it goes.

I will give a more accurate report as soon as the weather starts to heat up.

I will say this though, the shop Bill was just over 300 dollars-

150 of that was "Cut and Crimp hoses"- 75.00, and "Tighten fittings and check O-rings"- 75.00.

I was pretty unimpressed with that... but oh well, the job is now done.

here are a couple more pics.
