If you really want to do the heater and keep it military then I would try to find a descriptive manual for it online, that details the installation and removal. I'm not sure which one talks about the heater, but I'm sure the Army put one out there. I found a great TM 98014 manual for my M38a1 just by using Google, and was able to download all 390 pages via PDF for free! I have seen pictures and they look cool, but possibly complicated. Kaiserwillys.com has a newer heater (12V) that looks simple to install. Basically it's a squirrel cage with two vents. Looks nice, but it's $200 and 12 Volt.

This is an M-38A1 Hot Water Heater installation from a GI Issue Kit. It consists of hoses, fittings wiring, switch, resistor, ductwork and the basic heater unit with 24Volt blower motor that is used on the 2-1/2 Ton and 5 Ton 6X6 trucks of the 50's-70's. What makes it unique to the M-38A1 are the brackets and ductwork.
The part you see under the dash is the diverter, the handle on it directs the heat thru the defroster or down to the floor.
The installation works fine with the canvas or arctic enclosure. The heater must be removed to service the distributor which is not all that bad. I installed the kit in my M-38A1 38 years ago.
This heater is much more efficient than the type installed in the 1955-1971 CJ-5.

I have and installed one. It works quite a bit better than the civilian one I had installed in my CJ7, but it is a much more extensive install. Jon at Midwest Military has some for sale.

Copies of the manuals for both the hot water heater kit and the gas fired heater kit are free to download on our http://www.willysmjeeps.com" onclick="window.open(this.href);return false; web site and forums . Our web site is devoted entirely to the post WWII Willys/Kaiser/Ford of Canada and Kaiser of Canada military jeeps built from 1950 thru 1972.

The Army had warehouses full of these M-38A1Hot Water Heater Kits at one time. The heaters normally were not issued for installation unless the vehicles were being used in climates cold enough to require a heater. The majority of M-38A1 Jeeps did not get heaters. I used to do roving patrol at Ft Dix during the night in snowstorms at Ft Dix in M-38 and M-38A1 Jeeps with no heaters or side curtains.
The heater kits like the above will really keep you warm and toasty when combined with GI Issue insulated Enclosure kits.

Gian:

I do believe I have the majority of the components for this winterization kit hanging around my shop. I just finished getting all the parts laid out (just bought the jeep and spares this summer) so give me a couple weeks and once I get everything inventoried I'll figure out what it would cost to ship it to you. I was going to put them on eBay but it's not really a complete kit.

I 'think' I have the diverter, blower and case, and the big air hose. That leaves some water hoses and a switch, which should be easy. Gotta go dig............

It does take a few minutes extra to adjust the points on a heater equipped M-38A1. I remove the fender and heater, it's easier than most think
While you're at it it is a good idea to remove the distributor and the 18831 Brass Plug and Lubricate the WO-108874 Wick at the base of the distributor.
Hope these reruns are not too boring, the hobby appears to be marching to a slower cadence, but there are still newcomers out there who are eager to learn.
Did you spot the narrow diamond plate clutch pedal? Anyone know the story on them? It was O.D. color when I bought it with some DRMO Jeep parts way back when. I like it, I believe the narrow pedal is explained in one of the ORD 8 or ORD 9's for the M-38 or M-38A1.

The M-38A1 Hot Water really keeps you warm, more so than the 50's-60's CJ-5 with the factory heater.
