2017 3.5 EcoBoost all stock inch and a half level according to my OBD 2 torque app my truck wants to run 217 219 degrees and it's 61 degrees outside and my fans are on and touching the hose it does seem a little warm does anybody know if these engines tend to run a little hot or should I take it to the dealer as I have plenty of warranty left on the vehicle thank you

 

My 2017 5.0 pretty well stays at 205 and only goes up temporarily while towing. Hopefully someone with the 3.5eco chimes in but seems hot to me.

 

My 2017 3.5 eco runs about 205* with 90* outside temps

 

Newer vehicles are designed to run hotter than in the past for those great mpg's and all. Are we talking water temp or tranny temps??

 

That is engine temp when driving down the hiway at 65 with outside temp of 61 degrees

 

The shutters are closing at speed and causing the temperature to go up. Turn on your a/c for a few minutes and watch the temperature go down. With the a/c on the shutters will open. My 5.0 runs about 200 to 205 in the summer with the outside temperature at 110. Today with the temperature at 80 degrees and no a/c, the water temperature was at 218 when I pulled in my drive after about 12 miles of city driving.

 

This is true. My 5.0 in the summer with the A/C on stays about 197-205 but in the winter it runs hotter. I also notice in cold weather the shutters mainly stay closed or partially closed and the computer uses the fans to control temperature.

I did a test with my truck to see at what temperature the computer commands the fans on. With the A/C off the grill shutters will close and the fans are off. When temp hits about 215 the shutters start to open at 220 the shutters are completely open and the fans turn on. The fans run until temp goes down to 205 then they turn off and the shutters close.

New engines and transmissions are designed to run hotter.

 

"New engines and transmissions are designed to run hotter."

My question is why run the engine hotter?

Better fuel economy ?

Or to meet EPA standards?

 

The shutter blades are easy to remove, you can do it right through the grille with everything in place. Maybe yank a couple of blades so there is always little air going to the radiator? I removed most of my blades to make room for a secondary heat exchanger on my supercharged 5.0, and immediately noticed longer warmup times. One of the biggest benefits of the radiator shutters is faster warmup times, which would be beneficial to any vehicle, even a performance vehicle. Warming up the engine faster reduces overall engine wear, and improves economy and emissions.
The issue I have with the shutters is Ford was very aggressive with their aerodynamic drag reduction goals, keeping the shutters closed or partially closed much of the time to reduce drag. The result of that is the engine runs a bit warmer, which also means the engine bay is warmer overall, impacting heat soak and power. For a stock truck its not a big deal, but for guys who are upping turbo boost or adding superchargers, it can make a big impact on performance, which is why many of us end up removing or disabling the shutters.

 

Bad advice for people who are not increasing turbo boost or supercharging.
