So I modified my t stat housing to take a 192 degree stat and it’s been running great with it. The needle sits straight up 12 o clock now under normal driving. However today was towing my small trailer and noticed after a long climb that the needle was up a bit higher than I had seen. It was at about 2pm. Is this normal? I didn’t hear any extra fan noise or anything, although I never have so I don’t know if my fan clutch is even operable honestly.

Did you have the AC running while you were towing?
If so, you were probably at around 215 F.

The factory temp gauge is practically useless.
It will give you a overheat warning though.
And engine will try to save itself by reducing fuel and power.

Yes ac running and 82° ambient. The trailer is low and light though, can’t even feel it but it’s probably 1000# as it sat today. I guess I need to get the torque app going. I was having trouble getting engine read outs and don’t even know if that’s possible or not.
