Almost forgot - lol, The fan will cycle whenever the A.C. or Defrost is selcted. these 2 are on a different circut. I think you mentioned that the temp sensor worked, But alot of cars I see have more than one sender. (one for temp gauge) God forbid they make things easy by just using one! an easy way to test the sensor is to hold it (with pliers) over the stove briefly and check for continuity with a multi tester. Although I'd be willing to bet I'ts a fan relay. Also remember that the fan can start at anytime, keys or no keys so try to keep all your digits  But on the bright side, you know your fan works. Good Luck!

My truck heats up while towing about 6000 lbs while going up a modest grade. The temperature has reached 230 degrees on the guage and I get a warning beep and message to check guages. At this point, I will drop from 55mph down to maybe 40, sometimes even less to keep the temperature from climbing any higher. This problem occurs even after the cooling system was serviced by the dealer which included replacing the thermostat, replacing the coolant, and cleaning the radiator fins. The outside air temperature has been about 90 degrees. I don't think that I should have this problem with a Cummins Turbo Diesel, but this is my first truck and first time towing this much weight. Any ideas? is this normal? On interstate 80 going up to Lake Tahoe, I've had to drop down on the steeper portions to just 25 MPH to keep the truck from overheating.

If you re-do the radiator and that doesn't work, you'll have to get a more serious trans. cooler....your transmission can send a great deal of heat to your radiator.
