No, not always.
A fan that is connected to the engine will turn whenever the engine is running, an electric fan will only run when the engine is at the proper temperature, some also turn on whenever the AC is on.
TO COOL IT DOWN
Yes, if it is a 12 volt DC fan.
The fan turns on when you turn your car off so that the engine will cool down faster. It should only run for a few minutes, 10 max. But your fan also runs when your car is on not just when it is turned off.
fuse, wiring.... how long do u let it run before turning it off??..I would look to the fan relay next. also the electric fan thermostat if the car has one
get in the car when it is cold, turn on the ac, then check under the hood. the fan that is not spinning when the car is cold is the cooling fan
It's probably the catalytic converter fan; not the a/c fan.
turn the engine off try turning the fan if it doesnt turn the clutch on the fan is bad it
if its not turning on then its broken.
Loose or glazed fan belt?
If the AC or Defroster is on, many vehicles will also turn on the cooling fan.
