Re: Radiator question

Electric fans put the original electric system into fits unless you up the alternator and rework the battery guage wiring. I put electric fans on my truck but now realize it was not worth the effort. Is it possible the serpantine system you are using is spinning pump and fan too slow? Can you reduce the pulley size on the water pump increasing the pump rotation per engine rpm?
