Just run it the way it was made and you won't have any issues as long as the truck is in good working order.

Texas Heat Quesetion
It is almost summer here and its going to be a scorcher. Can I install and aftermarket thermostat to help my truck cool off sooner/help keep it cooler? Any reccomendations?

Just a heads up........2 of my trucks F150 with the 5.0 engines 1 year apart on the repairs did not accept aftermarket thermostats !!
Both trucks stats were replaced while doing other work....both over heated barely out of the shop in +70 degree summer heat here in ontario..
Improper stats caused my electric fans to constantly run @ extreme high speed & would not shut off !!
I strongly believe it was either a lack of, or over excess coolant flow thru the system ??
Have also heard the same (in Texas) of 1 forum member using a Duralast thermostat (Advance Auto) & had the same issue ,,,so Beware
Fix of course was to use an OEM thermostat.........

And, if it's a diesel, they like the heat.
And, either way, gas or diesel, it would need tuning to compensate for any cooler stat installed.
Quite a few things dependent on the t-stat temp in the ecm.

The Power Stroke uses two thermostats that open at different temperatures so I'm not sure I would mess with the thermostat setup unless you really know what your doing.

Sounds like the days of old when we'd put a 160 t-stat in our hot rods for the summer. New stuff doesn't work the same.....leave it alone. If you want to feel like you're doing something good (but really won't be) install an aux electric fan to an upfitter switch.

Yesterday it was 105 in the Billings, MT area. Had to pull our Jayco Pinnacle home 65 miles from the dealer after some service items were resolved, in the heat of the afternoon. Had AC on high, 70mph. Temp gauge got up to 227 pulling one hill when truck had to get into 4th gear, but generally stayed around 209-217 degrees. Got down to 199-205 on flat land.
I would like to explore options for adding an additional trans cooler and radiator if I were keeping this one long term. Maybe when the 2022 gets here I can explore those possibilities.
Worst overheating issues I've had was with a 1971 Plymouth Fury III when trying to pull a trailer out of the Bitterroot over Lost Trail Pass and a 2013 BMW K1600GTL when sitting in 95+ degree traffic.

For what? You were well under any critical temperature. The fan won't even lock until 230 degrees and you won't hit derate until 245. Trans temperatures below 260 are fine also.
