Should Both Radiator Fans Be On

The radiator fan is normally controlled by the ECU (electronic control unit) which is the brains of your car. The ECU knows when to turn the fan on by the temperature sensor near the thermostat reading the temperature of the coolant and sends a signal to the fan relay.

The fan should kick on once the coolant gets above about 200F and cars are programmed to allow the fan to cool the engine even if the car is turned off if the temp is above 200F. No need to worry if you notice the engine fan stay on even after you park the car.

Most thermostats open at around 185F and the fan should come on at about 200F. Generally this takes 10 to 15 minutes of idling. The radiator fan is normally controlled by the ECU (electronic control unit) which is the brains of your car.
