Auxiliary Coolant Pump
I am thinking of installing a separate 12v coolant pump in line with the hoses that feed my flat plate. Often, when I reach destination, I want to wash with hot water, but without the engine running, coolant is not passing thru the plate. With another pump, we would all be able to wash, even shower, with the heat still contained in the engine, if only the coolant was circulating. I'm wondering if such a pump would restrict the normal flow during driving, when the pump is off. Any other ideas?
