the first # range isnt unreasonable for hwy speed with some headwind in hot weatherMine runs around 219-222ish had the dealer check it out because I thought it was running hot after the coolant flush. They said it was running at normal operating temperatures. I'm also in 90+ degree weather, it hit 233 in 115 degree weather on a road trip going up a grade at 82 mph. Which is why I had the dealer check it out.
the new thermostat from ford dropped mine a bit, now its 212-216 going like 80 with some boost cause of headwind. 199-206 regular driving.
