Whats up fellow owners! I have been noticing somethings and I think its the radiator but is it normal that after I turn my car off and the key is out that the car makes a sound as its cooling down?

It sounds like the AC is still on or maybe its the radiator, Im not sure but its def a loud noise like air blowing. If I go and put the key back in and turn it, then take it back out the noise is gone the blowing stops..

Any info? Thanks

 

If the car is hot the fan can continue to run till it cools of...that is normal
