If you are having cooling issues you should know Ford quietly redesigned the thermostat in 2022. Replace it now if you have the old one. The problem was the thermostat sticking closed. The other thing to know is thermostats do not last forever and should be replaced every 50,000 miles or any time a cooling issue is identified. So even if replaces with the new one understand it eventually will wear out.
Here is a cooling checklist...
#1. Check the active grille shutters. I disconnect mine for the warm months over 60 degrees. Must be disconnected while the vehicle is on, AC on which will open the shutters wide open. Do not disconnect with shutters closed. Doublecheck the shutters after disconnection. Are they open? See radiator?
#2. MAIN part: The thermostat should be replaced with most current Motorcraft thermostat. The thermostat was redesigned as the old thermostat was sticking closed. Get it off of Rockauto. If you have old thermostat which came with truck replace it now!
#3. Secondary part: a) spark plugs/coils...only use Motorcraft most current b) engine cover...remove and set aside c) airfilter...only use Motorcraft d) radiator reservoir pressure cap.
