The engine is running too hot. It is a 6 year old car, so you need to service the cooling system. Drain and flush the cooling system, replace the thermostat, clean the front of the radiator of all debris, and reinstall a 50/50 mix of the proper anti-freeze and distilled water. I also have a 2001 impala with the same problem - both fans stay on. This happens even if I turn on the engine (cold engine) and shut it off right away. Thus, I do not believe that the car is overheating. I was told that it maybe related to the air conditioning system, because usually both fans only come on -when the engine is hot due to the extra heat from the air conditioning. I was also told that it could be a sticking relay etc. My Impala has about 70,000 miles and the cooling system was flushed a couple of years ago. I think the answer given was too simple and most likely incorrect. It is interesting that I have a similar car wtih the same problem. Don I got some info from another web-site & it seems to work: With the engine off and the fan running disconnect the negative terminal from the battery. Reconnect the battery ~ this is suppose to reset system. Don

What causes the water temperature to rise when the car is turned off after running?
A certain amount of the energy carried by the cooling water, is kinetic energy, from the circulation through the cooling system. When the engine is turned off, the water stops circulating. The kinetic energy contained in the water is converted to heat, thus raising the temperature of the coolant.
