Both my water pump and dual radiator fans are controlled by a on/off switch. When driving the water pump runs continuously.
The fans cycle on and off at a predetermined temperature. I have it written down somewhere, but if memory serves me right the fans come on at 185 degrees and off at 165 degrees.
In my case they are controlled by my fuel injection ECU with a sensor on the intake manifold crossover.
