Attention: TDR Forum Junkies 
Hey guys. I am in need of some information. I acquired an arctic heater from a piece of heavy equipment, or similar to what's used of buses to provide warm coolant flow for heater. For those who don't know what heater I'm talking about, see description below. I am in need of information on what options I have to plum my coolant lines.
My original idea was to directly "T" into the heater core water lines. This would allow the heater to run with the same water flow as if the engine was running. But then I realized that the water would have to flow through the water pump, with the engine not running. I don't think the water pump would allow that, does anyone agree or disagree??
My second idea, and better idea, was to use the NPT locations on top of the cylinder head, same as the heater core uses. This would be easy on the cylinder head for water exiting the engine. But my problem is where to put the water back into the engine block. I could use the NPT port for the 110V block heater, but I was trying to leave that in place. Although I would not need it, if my arctic heater works properly. Are there any places in the engine block similar to the block heater location that would allow me a return from the heater into the engine block??? Thus making a complete water circuit flow.
DESCRIPTION OF ARCTIC HEATER.
The arctic heater is diesel, JP8, or kerosene powered. It has a separate "dosing" fuel pump. It's own ECM. Has an intake and exhaust. Heater will heat 10 gallons of coolant from 0 deg F, to operating temp, in several minutes.
