What tells the cooling fan to come on?
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.
Will a bad thermostat cause the fan not to work?
Broken Thermostat
Thermostats are known to go bad and cause all sorts of cooling issues. ... If this thermostat doesn't open when the engine reaches the working temperature, the coolant will stay inside the engine block and the engine will start to overheat. This will result in the radiator fan not working.

How long can a car run without radiator fan?
Typically, you would be alright for the first 5–7 miles or about 2.5 minutes which is when the thermostat opens up and you can get heat.

What does a bad radiator fan sound like?
