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.
The cooling fan generally does not run when the car is cold, but could be wired directly to the battery so that when the ignition is engaged, the fan comes on. This is not a factory modification but is often accomplished if the car tends to run hot.
the radiator could still be warm or if the car is cool and it runs you need to replace the fan relay switch.
No.
The electric cooling fan or cooling fan temp sensor may be faulty.
With many cars now days, the fan may continue to run after the car is shut off, or they may even start and run for a while after the car is shut off. An engine will actually get hotter for a short time after being shut off. Sometimes that will trigger a sensor to turn on the cooling fan. If it continually runs after being shut off, it could be a faulty temperature sensor, or a faulty fan relay, or even a bad computer.
Some cooling fans will stay running even if the car is shut off to cool down the motor. Once the fans thermostat gets tripped to shut off, the fan will continue to run.
If you have a problem with your cooling fan it may be an electrical problem. You don't want to drive you car in this condition because it can run hot.
Bad temp. sensor? on most ford contour cars the cooling fan only runs when the motor reaches a certain temp. this model car also has a cooling fan relay switch,if the switch is bad the fan will not run.
If the AC or Defroster is on, many vehicles will also turn on the cooling fan.
the Fan motor will keep running fort a short time after the car is shut off. the motor actually gets hotter after it is shut off so the fan cools it for a few minutes before cutting off. Actually, on all the mid 80s 300zx engines, there is a fuel injector cooling fan that directs cooling air on the injectors for a specific amount of time after the car has been run at normal operating temps and then shut off. Is your car a turbo z? If so then the fan that comes on is the fan that cools off the turbo after the key is shut off. Maybe you have an aftermarket fan set up for the air conditioner, but there again they usually come on while idling with the air on, but they generally shut off when the key is turned off. The fan is not used for cooling the turbocharger. The turbocharger itself is watercooled and does not have a need for a fan. The electric fan is for cooling the fuel injectors as mentioned in the previous post.
The car has an electric cooling fan that is temperature controlled. The fan will sometimes run for a while after the car is turned off to help cool the engine. If the fan doesn't stop after 20 minutes, then you can start looking into problems with the relay, or the coolant temperature sensor.
It's probably an electric fan that reacts and works if the engine reaches a certain temperature. Sometimes that means keeping going for a while even after you shut down the car.
