Are you sure it was not the fan shroud that was rubbing the hose, as there is a TSB on that issue. It seemed to occur on 2004 models, mine among them, and the fix is to turn the hose a little, which moves it away from the shroud.
I really can't see the fan hitting the hose when the engine has stopped because it would be too obvious and the hose would not last too long.
I would think that if some object was in the heating fan area it may hit the fan there and that has certainly occurred before.
