I find it hard to believe that some water temp gauges don't go up while pulling a long hill/grade in warm/hot temps (especially w/ A/C on). My semi runs about 195*. With the 1 hill I encounter, heavy load, water temp will go up to about 225*, fan comes on and temp goes down. My old '03 SD w/ 6.0 would do same thing. Want to say too that current truck, temp will go up some, fan comes on and back to normal. Oil/Trans temps higher than normal on long pull.
Same here. My DD13 will run right up to 225 ,230 when pulling a big hill like fancy gap.
