Fan is still running after i turn the engine off

On most modern vehicles the engine cooling fans are electric. These fans are thermostatically controlled and will continue to run even after the vehicle is turned off and until the engine cools down. If you feel the fan is running an excessively long time after you turn off the vehicle, I would recommend you have it looked at by the dealer.
Good luck.

depending on the engine temperature the fan is supposed to remain on after you turn the engine off, until the engine reaches a preset cooler temperature. when it reaches cooler temperature usually within 5 minutes or so it should cut off... if you cut it off and it is running 30 minutes later.. then there is a problem with the fan relay or temperature sending unit.

You may have one conventional belt-driven fan with a thermal clutch and the other electric or, both could be electric on your car.
The cooling fan that operates during non-AC operation (just a running engine) if electric, will be controlled by a thermal switch in the lower radiator tank and may not turn on at all unless the engine is warmed up. The belt-driven fan should be turning at some speed all the time if the engine is running and at much higher speed with a hot engine.
The fan that cools mostly when the AC is operating won't run under normal operation but may turn on in hot weather (or when the engine is under heavier loads) even without the AC operating.
Checking them would require having a warmed-up engine and the AC turned on. Both fans regardless of type should be turning then.

How long does the fan run after you turn the engine off? It is normal for the fan to run until the engine temperature is reduced. But if it doesn't turn off at all, then I would check the fan thermostat, it is probably bad.

with the engine running and at operarating temperature,underneath the front of car? do you see fluid running onto the ground?with engine running hot standing still,,is your coolant fan coming on? you should see it turning on the front engine side of the radiator.visually. ok check this also with engine running, turn the a/c on does the other fan come on when you turn the a/c on? if so,then the a/c fans ok. when your engines running,and it overheats sitting still,do you see at least one fan moving? if not,turn the engine off. try turning the main cooling fan by hand.if it does'nt turn easily,it's bad or locked up.does it wobble when you try to turn it? if so,it's bad. if none of the above,open the main fuse panel under the hood,check main fan relay,or fuse ,for fault. the thermostat may be suspect also.you've had the thermostat replaced already,but when you start the engine and run it,does the main engine fan come on to do it's job? if it does,then i would suspect a bad thermostat. easily replaced at a small price for part,minimal price for labor.$40.00 for thermostat replacement is usually high. $15.00 for part is usually a high price.try auto zone.advance auto parts. never replace w/used thermostat! thank you for choosing fixya.com

This can be due to a bad relay or coolant sensor that turns on the fan or a bad fan, a good test to do to see if the relay and the fan work is to start the engine and then turn on the ac, if the ac doesnt work then unplug the coolant temp sensor this will turn on the check engine light but it will reset when you restart engine, if the fan turns on then fan and relay are good and its the sensor, if the fan doesnt run then it may be the relay or fan, a quick test of the fan is to dissconnect plug to fan and run a power and ground wire to fan and if it runs then you have a bad relay,hope this helps,

cooling fan will not come on until about 230 degrees, if fans still do not work. check the fuses and relay. if ok then run a wire to fan from battery.on fan side connection, run a wire from battery positive to fan connection. run a wire from negative to ground connection.if fan will not come on it is either bad or the coolant temp, sensor is bad. because this sensor send info to pcm from various running conditions. it is very important that this sensor works. it can cause;

Extended crank time when the engine is cold

Poor fuel economy

Spark knock

Lack of engine power

Erratic and/or high idle

Engine cooling fan stays running all the time

Engine cooling fan fails to turn on

Engine overheating

You are talking about the thermo electric cooling fan, its operation is independent of the car's electical system. It is switched on and off by the engine temperature. When you park, the engine heat soaks upward to heat the thermostat turning the fan on. It will run until the engine cools down and the thermostat switches it off. Quite normal operation.

some cars do start up the fan when turned off after they have been driven. as long as it is not starting when the engine is cold there is nothing to worry about. the reason it took 15 mins to shut off is that with the engine not running the water is not being pumped
round the engine thus cooling faster. hope this helps

why does the cooling fan start working as soon as i start the car and doesn't shut off until i turn off the car?
