I have a 2004 6.0/5sp auto. When towing and going up hills, what I assume to be a cooling fan comes on intermitently. This fan is loud! I mean, it sounds like a 747 is taking off from under the dash. I am wondering if this is normal, as I have not heard anyone else mention it. This truck has 68K on it, and is totally stock. What's the scoop?
