This was first brought to my attention a few months ago. I have a 2008 Taurus X. After the car is driven then cut off. The radiator fan runs fora longer than normal duration. Typically it's what 1-3 minutes then cuts off. Sometimes it runs for around 10 minutes. It's very loud whenever it does this. I just replaced the battery the other day be cause it was dead and she's out of town with it. Im assuming a relay is hanging up. I checked on it an i am being told it's all one unit molded into the fan shroud assembly. Any ideas as to anything else before i drop 175.00 for a replacement fan? Thanks!
