The operation of the fan is controlled by an independent engine temperature switch. Depending on the temp. of the engine block the fan with switch on/off. It's not uncommon for the electric fan to switch on once you stop the engine because the flow of radiator coolant through the engine stops when you turn the engine off. Without the coolant running through the engine and radiator the temperature of the engine will spike for a short time triggering the electric fan. It should shut off after a few moments.
Broken engine fan temp sensor.
Engine hot and fan cooling it down?Fan temperature sensor bad and it just thinks engine is hot and needs to be cooled down
Check fan relay
When operating properly, the cooling fan stays on until the temperature drops to normal.
The engine cooling fan is not suppose to stay on. The temperature sensor on the motor tells the fan to kick on if the motor ever gets too hot, usually comes on at 210-215 if I remember right.
A Volkswagen Jetta radiator fan is controlled by a fan relay. If the relay malfunctions the fan could either stay on or not work at all. An engine diagnostic would be recommended.
The fan is usually meant to cool the radiator. It shouldn't be anything to worry about. Since the radiator cools the antifreeze that has come from and circulates through the engine, as long as the fan is running, the coolant is remaining at a good temperature and you won't have to worry about overheating.
The fan will run continuously if the A/C is on or the heater is set to Defrost. If that is not the case then either the thermal relay for the fan is stuck closed or the engine is running hot.
If it is an electric fan, NO. If it is a mechanical fan test it to see. If you can turn the fan by hand with the engine not running it has a clutch.
it's probably designed to stay on a while and cool the engine. I would want confirmation on that though.
yes, the engine fan need to b running whenever the engine is on the fan is to cool radiater, it only comes on when the engine gets to warm, to cool engine down.
The thermometer that reads your engine temperature, I presume, is damaged or broken. Without the gauge to tell your fan how hot your engine is it will keep running as a 'better be safe then sorry' feature.
