OBTW, the cooling fan on my 07 5.9L Cummins would run (be engaged) even when the engine was not even warm -- IF you had the A/C on and the vehicle was traveling at slow speeds, like when you take off from a light. When the vehicle speed was high enough to get enough air flow through the cooling stack, the fan cut out.

Yeah I'm sorry, throughout this whole thread my initial fan question has been a distraction. THe issue was that it was running hot, I noticed because the fan came on at a time i did not expect it.
THanks for the info on the heater fitting.
