Ok, this is interesting, I just replaced my t-stat due to it running 176f-190f max. Used Motorcraft OEM replacement, just test drove it, cool here, mid 40s, max temp coolant was 188F. This was after 20 mins of street driving and 20 mins on the freeway 65-80mph. So I am a little concerned and confused. Anybody have any thoughts or ideas. One good thing, differential never more than 10.
Thanks for any ideas, or if this is ok and no worries.

Just for another data point...
My truck's ECTs run 194-196 in the summer, and 188-190 in the winter, at highway speeds on flat grades.
Radiator, oil cooler, thermostat, and coolant have all been replaced in the past two years.

Thanks fellas, yep, someone else discussed the idea of a sensor or the Scangauge being off a tad. Problem is that us desert rats are candy butts with "cold" weather, I think it is cold out, when in fact it is at least 40F everyday, sometimes to freezing at night. That is how I define cold, much to the chagrin of our North Dakota farmer relatives...who seem to show up in Tucson alot in the winter.
