car is running fine, the niddle of heat gauge on the dashboard is between 25% and 50 % of heat while car is moving, and shows about 55% when car stops at a signal, and goes back to less than 50 % when car is moving.
the probelm is when car is ON but not moving for couple of seconds fan turns ON and I can feel the vibration of it like its running full speed.
and it stays ON for about a minute after the car is turned OFF. I can hear the noise of the fan even if the hood is closed.
and if I turn ON the car after say about 1/2 hour, I can't here the sound or feel the vibration.
I think It only happens when niddle on temp gauge crosses 50 % mark .
car doesn't overheat . no effect on the mileage.
plz help me with this
thanks in advance

Something is wrong.. When you come to a signal the temperature gauge should not increase unless you just climbed up an 8% grade for 10 miles and the outside temperature is 90F.
You might have a pocket of air trapped inside the engine. The cooling system should be bleed. Another possibility is that there is not enough coolant in the system.
The fan running after you turned off the ignition sounds normal to me. Probably the fan sensor is detecting an over-heating situation.
