    Resolved--2016 3.5L Ecoboost Temperature Gauge Slow to Rise to Operating Temp

    My temperature gauge is very slow to rise to show normal operating temperature. In 40 degree weather I get heat pretty quickly, so I assume the thermostat works, but the gauge sits at minimum forever. It takes 20-25 minutes (10 minutes on streets/ 10 minutes on highway) for it to get to a normal operating temperature reading. Is that what everyone else is experiencing?

    I get the same thing, and hadn't really noticed it until this winter. I have noticed that if I punch it (the throttle, not the truck) after the truck has warmed up, but still showing cold on the t-guage, it will jump to the correct "normal" temp.

    I've got the opposite problem. I have a 16 3.5 and the temp is in the middle of the guage within minutes. Maybe I've owned Japanese cars for too long (Pontiac forced me away from anything American). I'm used to it taking 20 mins to get warm.

    Use ForScan and turn on the numbers above both gauges and you'll know what the actual temp is.

    So worth it!

    I assume this option isn't available on the XLT package, or is there a trick? Is that the same thing that shows the boost gauge that I can't seem to find?
