seems like a common problem unfortunately. Fan ran at either high speed or not at all.

just following up on this. Replacing the fan assembly. I found the dorman part at rockauto for $155 shipped. http://www.fordedgeforum.com/topic/12731-radiator-fan-assembly-replacement-procedure/

Recently noticed that the radiator fan is noticeably running for a longer period of time and running faster (louder) than I remember it being in the past. It will come on within about 30 seconds after starting the car in the morning and will run for about 5 minutes.. at least long enough to get out of the neighborhood. When I get to work, and shut it off, it's running and continues for a good 20 seconds. Seems to me that before it would take longer before the fan would kick on. I understand that while idling it will come on if sitting for a while, but doesn't seem like it should kick on right after a cold start.
