The fan is electric. It's powered by a relay that is connected thru a fuse directly to the battery. That relay is commanded by a coolant temperature sensor that should be located on the radiator. The only things that can go wrong here are the relay or the sensor - one of them gets stuck on the On position. To find which all you have to do is to disconnect the sensor: if the fan stops then it's the sensor, if it doesn't then it's the relay. Replace the broken part.

Mercedes Benz GL320 fan turns on after car is turned off. Stays running until your turn the key but you do not have to turn the engine over for it to stay 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.

When I turn the engine off the engine cooling fan stays on and does not shut off


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.

1993 OLDS CUTLASS CIERA Engine cooling fan SHUTS OFF WHEN ENGINE IS TURNED OF, THEN STARTS RUNNING AGAIN 30-40 SECONDS AFTER ENGINE TURNED OFF. hAVE TO DISCONNECT THE BATTERY TO STOP IT.


Sounds like the fan relay is failing, altho normally it keeps powering the fan as you turn the key off.
I suppose the spring could be weak and allowing the points to close.
I would change the relay and see what happens.

I have an 89 Olds 98 Regency. The fuel pump comes on with the key then shuts off less than a second later. Does the fuel pump need to be replaced or is there a relay module that could possibly be the...


The fuel pump will come on then, shut off when the key is placed in the ON position, this is normal. What is not normal, is when the key is turned to start the engine, and the fuel pump does not run when the engine is running at the same time. The initial power up you hear is a prime function that all vehicles have.
