    Running to cool is not good. You will waste fuel & cause the oil in the engine to sludge up. Your thermostat is not old, but not new, your thought of a stuck open thermostat is correct I believe.

    Do you have the "sport button"pressed or it modified to be always in sport mode? I kinda recall that in sport mode, the motor run at a cooler temp.

    Well I checked the thermostat. It's not stuck open in the slightest. Next idea anyone?

    How are you determining the water temp?

    Bluetooth obd2 reader. It's always shown around 210 until recently.

    Not sure what the deal was but I decided to put it back together as the thermostat looked brand new still. Running great at 220 currently.

    Correction. It's going up to temp while sitting. Moving it stays around 160

    Is your AC or heater on? I have noticed if I turn on the AC the temps will drop pretty quick.

    I do use it...my hand automatically goes there soon as I start it. But that's always been the case and it ran at normal operating temps before.
