Do the cooling fans of a 1998 Daewoo Nubira kick in when needed?

Hi everyone, I have recently bought a second hand 1998 Daewoo Nubira, it has two cooling fans behind the radiator. Just wanting to know if the fans should be turning as soon as the car is started or do they kick in when needed? Thanks.|||if thay dont run when the temp gets woarm enoff to close the conestion to them to produce a closed sercit then you should get them repaied and no thay dont start when the eng starts|||No, they come on when the engine temp get to a certain heat range. If the air conditioner is on, they should come on.|||Once the engine gets hot enough the fans turn on, after the engine cools down they turn back off.|||at any time motor is running they can and should turn on and off
