I had all my water hoses and coolant replaced, and that's when problem started. My coolant fans started staying on and running at full speed and they are very loud. I have to turn truck off at drive-thrus. The fans are constantly running even on cool/cold mornings. I've taken truck to my personal mechanic and to a local Ford dealership as well (twice) - this is not normal. Is anyone else having or have had this problem? I don't want to get rid of my truck.
