    • If you have en Ecoboost this is the one you want
My 21 Expedition was showing me 223 degrees while on the highway at 75mph. Did a little searching and found that this is typically the fix. Happy to report it made a tremendous difference - 20 to 25 degrees cooler all around. Easy to change with only three small bolts holding the housing on. Make sure the jiggle pin is at the 12:00 position so air can make it through. ... show more

    • Upgraded replacement for my 2019 F150 3.5 Ecoboost
Fit and worked perfectly. A word of caution. Make sure you get the correct gasket for this thermostat. There seems to be 3 or 4 options for this application.

    • 3.5 eco boost over heating solved
I changed out my thermostat in my 3.5 eco boost and couldn’t tow without overheating. Ordered this thermostat and installed it. It solved the overheating issue in this finicky motor.

My dealer wanted a crazy amount to change my thermostat. I was able to do it myself with this OEM part and save a ton of money.
