Hey yall. I'm looking for some advice. I recently purchased a certified pre-owned 2017 Ford F150 3.5L EcoBoost with 50,000 miles and I am noticing the engine temp running hot and causing the fans to kick on. I took it to the dealer and they checked for coolant leaks but did not find any. I have noticed that the engine temperature gauge begins to display the current temperature above 226 degrees. Apon accelerating up to highway speeds (80mph in SD) and after cresting a hill the temperature gauge reads 230-236 degrees. It usually disappears after 30-60 seconds however, after getting off the highway I can hear the fans blowing full blast. I only notice the temperature reading up in the 230's after accelerating to 80 mph or after cresting a hill. This happens regardless of having the AC or heat on and I am not toeing anything. This is my first ford truck and I am not sure if this is normal or if something is wrong. Any ideas on what is going on?
