i have observed that the normal operating temperature of the coolant is in the range of 195f-205f (90c-95c). it appears that the ICE will almost always run to keep the coolant circulating. wouldnt it make more sense to have a separate electric circulator pump whose sole function in life would be to run INSTEAD of when the ICE runs just to circulate the coolant? this could further maximize FE at the expense of a few dollars for an electric curculator pump; much like the circulator pump used in baseboard heating in homes today.
