Did the same for the 2003 C240 2.6litre V6 we had in the family at one time. Checked the WIS that Mercedes allow me access to because I Mod on MBWorld.
Manufacturer : BEHR
Refrigerant: R 134a
Material: Aluminium
Core Length [mm]: 200
Core Width [mm]: 305
Core Depth [mm]: 60
Mercedes now micro-encapsulate all cores to prevent bacterial growth & nasty smells.
I guess our Texan friend just persisted with his airbox design & upped the fan speed. The fan was particularly quiet for air moved & the system worked well. Probably not a Jag fan or motor. Where there's a will there is a way. Our W203 on a roadside pull off above Llandudno where I live. The shopping car of the family at that time. Still owned by a friend & pristine.

Thorson we are a bit late to this but should you need assistance in the rear evap. mount we hold all of the development drawings and instructions to install the period system in your car. Also and perhaps most interesting we have a NOS 420 system (in the box) that could be supplied. In fact we have 2. As to where the air comes from the in your face does give you a sense of quick cooling but the rear unit when properly aimed does a fine job in keeping the interior to the desired temps. A lot of development went into the units at the time and with the equipment they had a rear unit was the best compromise. Should you decide on an original system let us know. While there is a bit of work fitting any system it is the belt and pulleys that will give you the most trouble. In addition the original system had 2 condensers which when married to the large evaporator can turn the car into a deep freeze on trips.
I had a quick look: 60mm thick, 303mm wide and 200mm tall.
JB ~ When I see some of the amazing things you have achieved. This should be a walk in the park for you. I'll bet that Prof. Gregory's 1966 unit has a punch out somewhere that would allow you to run a convoluted pipe to the other side of the dash. There is room for that at least. Benz has a lot packaged in that console/dash other than HVAC. The CD driven sat/nav & telematics unit is pretty large.

Next time I'm at the junkyard I'll take a look at a MB Class, there are a few there. My priority at the moment is the Daimler, I think I have settled on using the system from a 1994 Lincoln Continental, but that's subject to change! Here it is after I removed it from the Lincoln:
@Jagboi64 - have you ever thought about using one of the Vintage Air units instead of something from a modern car?
They've got several different versions but they're easy to retrofit and adapt.
Just an idea.
Thorsen,
then your other option is to install the factory system which placed the evaporator in the trunk behind the rear seat wall. A giant evaporator to say the least, and giant hoses traveling under the car to reach the condenser and conpressor..
BUT: it is not a "in your face" system. Air is blown from the back of the car through ducting on each side of the interior above the doors. And cutting holes in the rear parcel shelf and floor is inevitable.
My S type and your 420 were not anticipated with a/c systems as they were with Seat Belts.
A friend in Tennessee did the Heater box modification in a MK-2. This was at a time when R12 refrigerant was available to consumers. I got to drive the car with a/c running and it was a pleasure. He cut two holes on the wood dash for vents and added two more on each side of the center console. Plenty air volume and force with a different 4-speed blower. With windows closed the car was very cozy inside. He insulated the box with modern stuff.
I don't know about the humidity, seems to me he had no issue with it.
Wait a second.
You are sayinig this system is factory option? My newly purchased 3.8 auto 1965 have shis system. It have a compressor on the dirver side of the front of the engine, and a giant evap box in the trunk. Its running on R12a now, and blowing super super super cold. I thought it is some aftermarket things, cuz its labeld Artic King?

I have, most of the ones that would fit are the classic underdash units, like Gregory has in his Mark 2. It works well enough, as the louvers can be directed to give the driver cool air , but I wanted something better. It's on my "someday" list.

Yes next time you have a chance take a look at a W203 C Class Benz. It might not be the ideal unit but its worth a look. Unfortunately it is operated over one of the CAN Networks or you could use the controller which is only about 12mm deep. But you might be able to mount components from it in a modified Jag airbox. We all have priorities but you are just the sort of guy that could make it work. If you are comfortable with CAN networks that would be a game changer.

I know that the luxury brands and many modern cars make climate control very sophisticated, but I just want a strong blast of cool to start that I can subsequently turn down to a steady trickle. All the computer controlled fine tuning is quite OTT for me.

US Dealers commonly fitted units like Artic Kar etc. The British units that Jag used OE for US & South Asia only were Delanair. They were not offered as an option in the UK

So funny and what a small world - that's my MGB!
I did the same thing on my roadster. $100 for the evap unit, $300 for a Saden compressor, $100 for a nice parallel flow condenser, $150 for vents, fittings, and hoses - and I am cool all summer long!

I know next to nothing about CAN. The reason I chose the straight 6 XJR engine for my Daimler conversion is precisely because it wasn't a CAN ECU, but separate stand alone units for engine and transmission.
I do understand the Ford EATC controllers well, and they use vacuum pots for move the flaps and a stepper motor for the blend door. That's easy to adapt and make a fully automatic climate control unit. Of course, manual cable controlled units would be even easier, but I would like an automatic system.

I always find these discussions about retrofitting ac to the Mark 2/S Type interesting. I've taken two approaches with a Mark 2 over the years. First was a Vintage Air unit about 30 years back which required a 2" bump out to the firewall where the battery was located to fit the largest blower/heater/evap possible. Airflow and cooling/heating/defrost functions were good, and losing the arcane heater box and blower in the engine compartment was a plus for me. The latest effort was integrating a complete system from an '01 XJR into a Mark 2. Every component was carried over in an effort to maintain the functionality and efficiency of the modern car - the only difference was the ducts connecting the blowers to the box housing the heat exchangers are approx 18" longer than the originals. Yes the second system is the better of the two and the climate control aspect is a really nice feature, but the fab work was very extensive and the difference isn't that great. I should note the earlier Jag was used in northern CA while the latest one resides in the hot and steamy NE. One factor I'd stress is the importance of efficient airflow through the heat exchangers - and through the entire system for that matter. For what it's worth I thought the Vintage Air unit was well designed and constructed. The major challenge is for the folks who don't want to disturb originality, and for that I don't have a good answer. Good luck with whatever path you take.
The center face-level vents are fed directly from the heat exchanger housing, while defroster, footwell and rear vents are ducted. Blowers are housed behind the outboard footwell covers.
Thorsen, The air box/evaporator you used on your MG looks like those sold by Old Air in the US and Car Builder Solutions in the UK. I wondered how it performs in terms of delivering cold, fan noise, and general reliability?
I'm pretty sure they all come out of the same factory and the only difference is the name stamped on the box.
The unit I put in the MGB cost $100 and blows a large volume of cold air. On 'high' the fan is noisy but not annoying. On 'low' it's almost silent. When I have the top up I usually run the AC blower on low or medium. If I have the top down I usually run it on high.
I have a big drive planned for the Jaguar at the end of next month, then I'll pull it into the garage and see what can of space I have in/under the dash.
