Several things may be the cause ...... fan no longer works, cooling fan relay no longer works, coolant temp sensor is bad, or maybe even the cars ECU is'nt telling the fan to come on. Ron J.
Simply bypass the cooling fan thermostat .G
engine cooling fan should not do this - bad temp sensor likely
Yes it is normal if you have an electric fan. The fan will run until the engine temp lowers to normal.
If the AC or Defroster is on, many vehicles will also turn on the cooling fan.
The engine cooling fan will continue to run because the engine is hot. Once the engine has cooled down the fan will shut off. If it never shuts off you may have a bad temp switch or relay.
If the temperature of your car engine is still very high after stopping, the car cooling fan will continue to run, and the cooling fan will not work until the temperature drops.The above answer comes from Suzhou Santian Precision Mould Manufacturing Co., Ltd.
Your electric engine cooling fan is controlled by one or more sensors in the cooling system, which turn the fan on and off depending on engine temperature. If a sensor is going bad the fan may run at any time.
The fan continues to run after the engine is shut off to bring the engine temperature down to a specific temperature so the cooling system does not build up excess pressure.
Check the temperature sensor and the relay (if applicable) No, it's not safe to run any vehicle without adequate cooling. BTW, many cooling fans will continue to run after the engine is shut down. If the cooling fan stops once the engine is cool, it's running properly.
It is the cooling fan for the engine. Even if you shut the engine off, the cooling fan will continue to run until the engine heat gets back down to a normal level. The fan can turn on at anytime. Watch your fingers.
Since most engine cooling fans these days are electric, they can (and will) run even with the ignition off and the key removed. This happens frequently after being run, and the vehicle senses that it needs to cool things down, so it will engage the fan automatically.
The temperature sensor activate the fan. Unless it was hot wire by a back yard mechanic.
