2007 VW 1.6 FSI 1KZ will shut off when at operating temperature. It will always restart and might or might not shut off again. Usually it happens after starting and pressing the accelerator. Other times it...


Have the 'Throttle' or 'Accelerator' re learn performed. Some will re learn as follows : Turn ignition to RUN with engine OFF. Push throttle pedal to the floor and hold it there for 30 seconds.

Turn ignition off and then release throttle. Start engine and allow it to idle until warm ( 80C.) Do not rev the engine or put it in gear dueing warm up. It must be allowed to warm up at idle only. When you hear the radiator fan come on, turn engine off. Wait 10 seconds and restart engine. Test drive.

This procedure MAY have caused the throttle to relearn. If the same problem is present, go to dealer or VW shop and have them 'relearn' the throttle with a scanner.

Heater fan for Chevy 1988 S-10 has gone out. I


Might just have been the right time for the fan to burn out. Buy a new one, junkyard parts are another option, but make sure you test it before you buy it.

Radiator fan runs after car is turned off. Only occurs when A/C is run for more than 10-15 min. Shuts off after a few minutes, but is concerning.


That is nothing to worry about the fan remains running after the vehicle shuts off in order for the engine to cool down. Once the motor cools down sensors trigger the fan to shut it off.

On a 1997 nissan sentra will the radiator fan run all the time the car is running


No, it should only turn on when the temperature switch tells it to. On a hot day you may hear it running even after shutting off the engine. The fan is set up so that when you are moving at enough speed the fan shuts off to save energy, when you slow down or stop the fan should come on to maintain airflow. If you check it at this point yes it should be running. When you start it cold the fan will not turn on for maybe 10 or more seconds when the engine starts to warm up. Hope this helps.

Things to be concered about; 1.) the fan never seems to turn on. This will cause your engine to overheat when you stop.
2.) Your heat is not working. The heat going away can be a sign that you antifreeze is low and that you are about to overheat.

I have a 2004 chyrsler sebring v6 and recently my fan started not shutting off when i turned the car off and now its killing my battery does anyone have any idea what would make the fan stay running even...


Check under the hood and see if you have a decal that says fan may turn on after car is turned off. The fan can run for 10-15min after shut-off.
If it's on for only that length of time and it's killing your battery, you may need a new battery.
If it's not turning off at all, open fuse compartment under the hood, take a small rubber mallet and start to tap the relays. There should be one there for the cooling fan. Once you find it, (the fan will turn off when it's tapped) you can exchange the relay for another (of the same part number - like the wiper relay or A/C relay or something) restart car, let it run til hot, and turn off. If fan shuts off within 10-15 minutes, you need a new relay.

Fanning running


If no engine lights are coming on, and the dealership has diagnosed it normal, I wouldn't worry. Electric fans may stay on even after the car is shut off to help cool the engine. Usually there is a warning in the engine bay stating this.
