Were both of these conversions for cars in New Mexico, or at least somewhere that is similarly hot? I wonder if the fan is on a lot in a hot climate, then electric and belt-driven pumps won't have many efficiency differences, whereas here in the Bay Area, in a milder climate, one could benefit from the switching on and off of the pump.
Just a thought, what do you think?
