My water pump turns on and off by itself as does my cooling fans. Two less things to think about at the starting line. Water pump turn on at 160 degrees and cooling fan come on at 185 Degrees.
Out here in Vegas we keep an eye on that water temp.....and with the electric fan and water pump....they cooled off....plus with the e85 helps....this dart has a 26 inch aluminum radiator in it...you don't want to get in a burn down with it...lol
