Question about 2002 Nissan Sentra

When should the radiator fans be running? They only seem to run when I put the A/C on. Should they run at other times? I have a Nissan Sentra 2002 GXE.

It is normal for them not run if the ac is not in use.
they are only needed to cool as the cars computer requests for cooling.
if you want to check them drive the car around for 5 mis or so and return home.
open the hood and leave the ac off and and the fans should turn on and back off as no air is flowing through the front of the car so as the water increases in temp it will begin to request for the fans to turn on untill it has cooled the water back down then they or it will turn off.

hope this helps

thank you

One fan should be on once the coolant temp hits a preset number, I believe it may be 205 for teh Sentra. The second fan kicks in once the AC is on.

1996 nissan sentra automatic...... engine makes a winding sound wile running ..? someone told me it mite be the power steering pump???? is that true ??? it happend after driveing throw high water...

If u drove in some water, all ur electrical components are wet and all the moving parts have lost the LUBRiCATiON! Check the ALTERNATOR if the sounds coming from that area u could just hear it while ur engine is running, check also the radiator fan turn on the engine and let it run till the radiator FAN starts up! The possible one is the FAN MOTOR, i have repaired such incident to wut happened to ur car! Hope that helps u! Taah!

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.

Nissan sentra n16 temp. overheating

If all of the things you replaced are working fine I am going to say double check the thermostat. Also make sure your fan is engaging at temp. You cam check by running till warm and then running the AC. If the car does not overheat with the AC on then your fan is not running under normal conditions (with AC off) This can be caused by a couple of different things depending on how the fan is set up. I am not a nissan expert

My 2002 Nissan Sentra overheats.

Do you mix your radiator fluid and have it tested to see what it is rated for, may be too warm and need more water if you mix it yourself. I would also check the fans on the radiator, they should be turning on at about half temperature on the temperature gauge. If not, then track down why they aren't.
