Greg;
I chose to use the coolant for cabin
heat. I found a nice 6”x 6” heater core in a catalog at NAPA, bought a centrifugal
fan from Lincoln Surplus, and built the housing out of fiberglass. Flexible
ducts carry the heat where I want it. Wired it for 2-speeds using a
resistor that is air cooled by the air inlet to the blower. Also
installed a standard automotive cable-operated valve in the coolant line to
adjust (or turn off) the coolant flow. Works great.
