Run the fans off a of thermostat sensor. You are not suppose to run a thermostat with a electric water pump because it dead heads the pump. I also found that they run cooler with no t stat and just running the restrictor.
Thanks, i never use t stats but was just wondering, in my dads car I used no thermostat with aluminum water pump, belt driven flex fan with no shroud, and a champion 3 core radiator. And during the hot summer months, even at the track never once has seen over 180*.
