What causes radiator fan to break?

In case of electric fans, the motor’s bearings can melt due to the heat, causing the blades to be dislocated. The fan blades can also break, emitting a rattling noise when the fan is running. The electric fan relay or the temperature sensor can also go bad, preventing the cooling fan from functioning properly.

Herein, what causes radiator fan to stop working?

Defective temperature switch, coolant sensor or other sensor. Engine thermostat is stuck OPEN (engine never gets hot enough to turn on the fan) Faulty fan relay. A wiring problem (blown fuse, loose or corroded connector, shorts, opens, etc.)

Secondly, can a broken radiator fan cause overheating? Your water pump can‘t circulate coolant that’s not there due to it having leaked out from one of the hoses! Your radiator fan pulls air across the radiator to help reduce the coolant’s temperature but a worn fan clutch or broken fan motor can‘t help to reduce the temperature and will lead to overheating.

Similarly one may ask, can you drive a car without a radiator fan?

Yes, you can drive your car without a radiator fan, but you never should. Your vehicle’s cooling system is crucial to its performance, and every time your engine overheats, you cause damage.

Where is the cooling fan sensor?

The cooling fan relay is normally located in either the underhood fuse and relay center or mounted to the electric fan assembly behind the radiator.
