Coolant temperature fluctuation ?

I have been driving with the Coolant Temperature digital readout displayed on the DIC of my 2020 3.6L XT5 for the past 6 months.

The thermostat is 194* and I expect the operating temperature should stay close to that. Mine, however, reaches 190-192 and then in a short amount of times, less than a mile, drops as low as 176 and then hovers around 180. It rarely climbs to the high 180's and then drops back down to 180 or less.

Curious what others are seeing?

I've been wondering about that. I haven't checked the DIC, but my temp gauge is below the middle area. I'm used to the temp gauge running in the middle of the gauge range. I'll check the DIC next time...if I remember! 馃榿
Where my temp gauge usually runs, can't find a digital display in my DIC...
