Re: Easy Question about cooling fan? How does the Radiator Cooling fan know when to Come
Tofuboy hit the nail right on the head. When the CTS sends back a certain voltage, it changes that into a temperature and when it gets so hot, it turns the fan on. All the thermostat does is open up to let coolant into the engine. If it didn't, the fan wouldnt turn on because the air rushing past the radiator would always be cooling the coolant and there would be no hot energy from the engine to transfer into it thus no need to turn on the fan.
