Does radiator fan come on with heat?
The engine temperature should trigger the fan to turn on. It will also turn the fan off once the engine has cooled to under 200 degrees. You may have heard of a part called the radiator fan switch or temperature fan switch. This is linked to a thermostat and works much like your home’s HVAC system.
Why do electric cooling fans sometimes turn on even when the engine is off?
