coolant temp operating range
Wondering the actual temperature range for coolant. I use a scan gauge to see actual temperature and would like to know what is safe for the 6.0 while towing a heavy load.

I am running an outlook and water temp sits at 195 F running on the highway with ambient temp being 50 degrees, no trailer or weight. Dont know about summer and towing cause I just put on the monitor this winter. My fan never comes on in the winter even pulling hills and driving hard. In the summer pulling the trailer, it will kick on the fan but I think this is at 200. At 205 it goes to full fan but I can't verify until later this summer.....

I sit around 200 running empty, have almost gotten to 210 just having some fun when it was around 80 degrees here. I will find out what it is likely to hit when towing this weekend, taking the big horse trailer and it is supposed to be fairly warm here on saturday, so I should get a good indication of what it will reach. 195-200 is a good operating temp for normal driving I do believe(or atleast that is what I seem to be hitting consistantly, so I hope it is).

Normal driving with no load I range anywhere from 188-195F. Towing down the freeway it usaully ranges anywhere from 195-200F and then towing up mountain passes I have seen as high as 213F (my fan seems to kick on at 210F). This is all based around moderate ambient temperatures (50-75F).

Without knowing your load that your hauling(while even knowing that if we don't haul that same load or close to it then it is hard to judge), and the terrain that your are going to go thru, your truck might run a little harder just because it has to work all that much harder for you then mine would while hauling. There are a few variables that change what you would see versus what I would see.
