Temp fluctuations

@capndtice · May 21, 2020

Anyone else typically running hair over 210 but bumping up to 220-225 fluctuations between that and 210 before settling usually at beginning of trip? No load- haven’t seen this happen when pulling my boat (4500lb load)

Yes I have this happen, it is usually when I first get on the highway and it will shoot up to that temp for about a minute then back down to 210

My truck does the exact same thing. Usually stays above 210.

2020 3.0 RST.

I had this happen once about 2-300 miles ago. Was moving a bed and saw the temp creep up close to the 230 mark. Then after a mile or so, it went back down to it's normal just a tick over 210. I have been watching the gauge to see if it would do it again but so far so good.

Mine did the same thing one time after climbing a hill on the interstate. Then it went back down to slightly above 210 and hasn’t done it since.

Guys these trucks run really warm under certain conditions. The cooling system is no a conventional system we are all used to. With the Active cooling system. These trucks normally do run 210+ Max Ive seen is 226. Why run it that hot you ask. only time I have seen it that warm is to increase the oil temps to the 230-240 range. As other's have noted the truck tends to by the gauge run cooler when towing. Yes they do. Lowest I've seen is 189f. But this time to lower high engine oil temps(268F). If you do monitor coolant/oil temps with an App or gauge assembly. Its rather neat to watch.
