Fan When i switch off the car, i still can hear the Fan *the one beside the roditaor*, the fan will stop after coupel of seconds, is that normal? another thing when i swithc the care on the fan will start working immediatley, and the you can feel the speed, some times it;s weak and some times it's fast, i would like to know if this is normal. Thanks

The most common cause of this problem is that the drivers seat heater grid is open or burned out. That is based on 25 years as a Ford dealer technician.

Hi Bajil, Have a diagnostic scan carried out and have the coolant temperature sensor and relay inspected for correct operation. It sounds as if a cable has become disconnected or that the operating circuit has become defective. The cooling circuit operation is correct when the fan operates when the engine temperature raises a fraction above normal. The fan will run for a number of seconds and then switch off, thereby maintaining the 'normal' operating temperature. Regards John

Fan switch has a replacement and wire from dealer Had replaced fan but did not fix it. Fan belt broke and car overheated. Stopped as temp went out of normal. This was enough for temp switch to stop working. Fan never ran again until new sensor and wire connector were installed. This was on a 1999 SC2 a Saturn mechanic told us this was a common concern.

if you mean "thermostat" valve .. then that can fail either open or closed . if it fails open then the engine will not reach normal operating temperatures .. if it fails closed then yes the engine will overheat .. another common failure is the radiator fan .. it only runs when the car is not moving .. as long as the car is moving then cooling air is available so the fan is not needed ... so if your car does not overheat when driven but overheats when stopped or idling then suspect the radiator fan or thermal switch (mounted on the radiator) .. that switch turns on the fan when the radiator gets so hot ... you can just listen for the fan when hot .. you should hear it .. .. if your car gets too hot while driving then suspect a bad thermostat or clogged radiator .. sometimes a bad water pump (broken implellers) will cause the trouble ..

Your electric fan is probibly not running.Fan switch,fan relay or the fan could be bad.If it is getting hot and you pop the hood you should hear the fan 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.

Yes, Massive air flow from the first fan is causing air to be brought in from not only the front of the radiator but from the fan right next to it causing reverse air flow through the fan. This intern can cause less dirrect airflow through the radiator. Also, the recirculation of hot air (from the first fan) into the second fan, across the radiator and back to the first fan can cause the vehicle to run hotter. Wile the car is moving there is enough air pressure from the outside of the vehicle to flow directly through the radiator with little fan assistance needed. If you have the engine running and and turn on the a/c, you should hear the fan change speed or even see the second one turn on (If the fan is working), there is no delay. You might have a bad relay and good fan, as there is a separate relay that activates this same fan for the a/c.

Fan relay is a good one for that and where I would start. Usually the cheapest to. But the next thing could be the fan switch.

thats sound normal..like i always say if it's not broke don't try to fix it..

As far as I know, this is normal. When I get out of mine, I hear the fan run for about a minute after I shut the car off.
