    I'm removing this heater to install the original style driver side firewall heater that has the fresh air hose to the grill and wanted to see if anyone can tell me what this mini heater im removing is originally made for???????? I have 2 of these that resemble an old soda machine or something that has 3 flip up flaps for heat to come out (one on each side) has a heater core inside and a working old looking blower motor. Like I said I have 2 of these and one still has the original nameplate on the front that says willys overland. Does anyone know if this is like a cj2a heater that was installed or maybe an aftermarket heater of the time?? maybe out of a wagon or truck?

    Definitely aftermarket, or at best "dealer installed".

    I'm betting you'll find it actually keeps things warmer than the factory setup.

    I may be interested in buying it for my 49 if you are going to sell one. Looks period correct. Cool.

    I have toyed with the idea of running this aftermarket one with my factory style both at the same time. Maybe I can be real comfy in the winter ;). But I probably will just stay with the correct factory one. Personally I think the factory 1 actually moves more air.

    Well, I guess if you hang out on here long enough you'll hear *anything* :shock:

    Someone finally has something *Good* to say about a factory heater :shock:;)


    You may be right on the factory one moving more air but consider- The aftermarket is re-circulating air from inside the jeep which warms up over time, getting hotter each time it gos through. :)

    The factory one is trying to heat up cold air from outside the jeep, which stays cold until spring. :(


    I suspect this is a lot of the reason why people find units like the Moab so much better than the stock unit, they aren't trying to heat the whole outdoors.

    I agree in general, Howard, the stock heaters are about like an anemic mouse breathing on your foot. But my early (one-owner) units had no outside air intake, and I believe they were "factory" or at least "dealer."

    The factory heater for 5/6's came along in '57, anything before that would have been aftermarket (although the firewall had knockouts laid out for a Harrison unit on the passenger side) The FSM describes both the cable operated & later vacuum controlled units as "fresh air" input- that would be the hose from the heater core box mounted inside the engine compartment to the scoop inside the drivers side of the grill. I may be wrong on this but I've got a few of these things kicking around & I don't see how they could work with anything except outside air- there's just no way to get inside air to the core in the engine compartment for air recirculation.

    I can tell you your photo is identical to the heater in my 1950 Jeep truck, which my grandfather bought "used" in 1951. Pretty sure it was factory.

    Walt, I respect your knowledge entirely, so much that I went out to check my 1957 CJ5.

    Here's what I know... The heater has NO outside air. It is marked 'Willys" on the metal front trim/badge. There is no air scoop on the grill shroud.

    I bought the Jeep from the original owner when she turned 99 years old. I have the Dealer Invoice dated 10-3-1956 for a "1957" Model. It shows "heater and defrosters" under "New car - Factory Installed."

    The heater is mounted under the glove box, entirely inside the firewall. It has NO cables or vacuum controls, or outside air intake. There are two electric switches marked "heat", one for a main fan on the rear of the core, which blows hot air out of slots to the side and bottom. Other switch is for a secondary fan on a top outlet, for the defrosters.

    I once had a '56 that I remember as being similar, but my recollection on that one is fuzzy.

    Hope this is of interest.

    Interesting- Harrison did supply aftermarket heaters with "Willys" badges, as they did with "Chevrolet", "Buick" & many others- same heaters, different badges. These were often installed by the dealer, here's one I'm in the process of restoring -

    Here's another one that belongs to Rondog-

    [​IMG]


    Interestingly enough my late 40's- early 50's "Willys Overland" script heater (that came out of a truck) has mounting bolts & pipes that line up perfectly with the firewall knockouts. Ron's later 'Willys" heater didn't IIRC.

    I can't argue with your paperwork however there is no mention of any such style heater in the FSM, parts books or the '55 owners manual. The general consensus on the board has been that anything that doesn't show up in these documents isn't considered to be "stock" or "factory".

    This has been discussed here many times before- do a search for "Harrison heater"

    Again, I may be way off base on this so if anyone has any '55-'56 literature showing that the Harrison (or other) heaters were indeed an official Willys option i'd love to see them so that we can answer this definitively.

    Mine is the same unit as in Rondog's photo. I assume that would be a Harrison? I'm learning something too, thanks!

    If it's any use to you I can email a scan of the October 1956 Dealer invoice. And/or photos as the Jeep heater looks today. The "factory installed" heater was included there under the list price (with directionals, oil filter and oil-bath air cleaner) - before the "dealer installed" accessories were added on.

    But who can say for sure who pulled the wrenches?

    The Owner's Manual that came in the 1957 doesn't mention heat at all, but it was printed 9-55, Second Edition.

    The heater water pipe holes in the firewall are vertically spaced about 8" and there seems to be an unused closely-spaced horizontal pair, lower and more to the outside of the tub.

    Do you have the cutouts on the driver side firewall for the "fresh air" heater?

    If not your machine is probaly actually a '56 model year.

    I'd like to see the invoice, can you post it here?

    ...No cut outs at all on the driver's side. The lower firewall pipe hole used for my heater appears definitely factory, and there is a second hole next to it ( about 3 inches horizontally towards the center) with a blanking plate.

    See PM re: the invoice.
