Personal heater and engine coolant heaters in the tm

[Ecscnvb]

Looking through the tm today trying to fix an issue I'm having, I stumbled upon the fuel burning engine coolant and personal heaters that were installed while the military had these trucks. Does anyone still have these installed, cause I've not seen anyone with them?

I have some sitting in the basement waiting for their number to come up, so they get installed. I collect a lot of parts that I am slow to install. Its so nice once I get them in though!

Here is an example of one installed onto an M939 series. Takes place of the heater core box and fan, it is an arctic accessory. I have this same setup, not installed yet. The correct M939 brackets to fit this 30,000BTU fuel fired heater to the heater core mounts are rare to find used, I had a guru do an NSN search and find an existing vendor for them because I'm not smart enough. There are also several examples of these installed onto numerous other MV's.

I have several, NOS, complete in wood crates with heater, control box, wiring, fuel pump/filter, and exhaust. Send $. On your own for brackets, I don't have the NSN for them anymore.

Unbelievably nice feature. Get in the truck, start the heater, enjoy warm air, start the engine, and go. Once engine coolant warm, shut off fuel fired heater and use heater core type heater that was then moved to under pass seat (my plan).

It is very similar to a conventional garage turbo/bullet heater, except these route the combustion exhaust separately out a flexible exhaust pipe. Lo/Hi setting which adjusts the fuel rate.

Control head, 30k vs 60k comparison, and 30k neatly installed in an M809/M35a2 cab using the stock defrost diverter box. Realistically, you adjust cab temp via how far the window is down. Several others here know much more about these than I. Cranetruck and gimpyrobb are 2 super experts in this area. I just collect them, and don't install them, same as gr mentioned above. Either have time or money, seldom both simultaneously.

Does this do the personal and engine coolant heat?

How much?

PM sent.

I don't have the exchanger to heat engine coolant. There is also an engine oil heater portion, I think it is really just a deflector which flows the heater exhaust across the oil pan.

Are these still avaliable

Yes. I have 2 personnel ones, new old stock. $500ea, 100% complete. 30,000BTU. The coolant ones are a bit more obscure. Most I have seen are non-functioning or in parts.
