It can be. On some vehicles the fan can even start with the engine off already.

It happens because, thankfully, your car is smarter than whoever is driving it! It has a thermometer, along with many other sensors, and when it detects that the engine is too hot for it's own good, it runs the fan to cool the radiator coolant. It's a good thing, don't worry. And no, it should have no adverse affect on the battery, because it's sensing that as well.

kenz,

I have a 05 (sedia) lancer 1.6 MT, its the same with my car, the aux fan runs around 5 seconds after turning off.

BTW, would you or somebody here know if the 04 and 05 models are the same? It would be great to form a group with the same body type lancer.. Any body else with the same idea? Even just to compare notes, share sources and experiences..

Ciao!
