Ok before ya go a modding with leccy pumps and thermo gismos, consider the basics first when ya motor is started from cold the water temp starts ta rise ,the wax thermo is shut, so most of your hot water goes to yer heater first, so ya can get yer heater on quite quick, then as temp reaches the set point yer thermstat opens and so cooling of the engine accurs, the very hot water is then pumped round yer rad, hence cooling and recycled again,so clutchy is correct ya dont take out the thermostat,so what will ya achieve with a electric pump , ans=nothing really maybe a twiddle bit more mpg as for bhp gains , na be like **** in the sea,so if ya want ta waste ya money,its your call,best oh luck
