Why do you need a radiator fan in a car?
To stop the engine from overheating, we take the help of coolants that flow through a radiator into the engine. The radiator’s job is to keep the coolant cool so that when it returns back into the engine, it is able to absorb more heat. A radiator fan is thus used to keep the temperature of the coolant in check. Thus, it has an important job.
When does the radiator fan come on and off?
With the A/C off… only the radiator fan motor comes on when the temperature reaches about 225°F and then turns off when the temperature reaches somewhere below 200°F. With the A/C on… both fans are activated and run continuously until the A/C is turned off. If your vehicle IS NOT A/C equipped.
