There are about 5 versions of that same heater. The difference is usually the locations of the inlet/outlet pipes. Do you need that exact heater?

Hope you aren't going to try and hook it into a ferret, as per the Canadian modification. I can't help but feel the engine will draw far more air through the crew compartment than that little heater will put out.

Dear Rob,

I am as you so very correctly deduced looking at assembling the raw materials to enable me to do that modification if I wish in the future. I am slowly collecting many parts for my Ferrets while I get the garage built so that I am ready to start when the garage is completed.

As an owner of another Ferret already I would agree that the output of the heater will be challenged to overcome the draw of the engine fan, byt none the less I would like one of the heaters.

I am not fussed as to the inlet and outlet positions, there is a way to switch that around from what I can see.

Do you have one around in your spares collection?

Is the NSN for this one the same as the heater installed in the M38A1 CDN2? I have a takeoff one avail. No duct hose but the box and cage fan.

The heater will be close enough for the installation Robin wants to do.

I do have this to say about these heaters. If you can find an old pre-1980s heater, it will have a much bigger heater core, and consequently put out a lot more heat that the post 1980 version. The MLVW for instance had the same pattern heater, but you were lucky if you could clear your windows with it on a cold day. We initially blamed the diesel for running a little cooler than the old gas engines, but I know now that it has more to do with the half size heater core in the newer heaters. I installed an MLVW heater on the Dodge M37 at work, and it does not produce the heat that the older heaters produced.

When I was still in, I hooked an Il** heater into the cab of my MLVW MRT. I also hooked a thermostat into the dash to control the heat to a comfortable 75°F. You did not want to wear a parka in that truck.
