Hi, Can I get some thoughts on this, it is my 2014 and the gauges read two different Temps is one more accurate than the other? I also noticed that after installing a front license plate the Temps have gone up.Thanks John
One is your coolant temp (right picture) The other is your oil temp (left picture)

The aero panel license plate blocks half of the air flow to the radiator. If you watch NASCAR at all, it's like when they add tape to the front grille to decrease drag at the expense of higher engine temps.
That is true, I'm still alittle concerned about the water temp.
Not sure why you are concerned about the coolant temp. It is right where it should be. To see accurate gauge readings put your Instrument Panel in Tour Mode so the gauges show up in digital format to the right of the digital speedo. The analog gauges in your pictures are based on voltage signals that are converted from the digital words passed from the ECM to the Instrument Panel. The digital displays require no conversion from digital to analog thus no loss of accuracy.

Well, what we DO know for a fact is that '14 MY analog temp gauge is nowhere near accurate (mine sure wasn't) nor even much more than a fixed 220 degree display

Someone had previously posted that on the 2014 C7 (Base? Z51? both?), the big coolant temperature gauge on the panel is actually a glorified idiot light. When the coolant temp reaches "normal range", the gauge goes to some "normal number" and stays there unless the temp get unusually hot or unusually cool, then it moves to a significantly higher or lower number that is still not accurate but does tell you something is wrong. Supposedly, this dumb idea was corrected for MY 2015. I can't verify if this story is correct, can someone else?
On our 2017 Z51, the temperatures are true analog, the gauges show small variations in temperature.

My '14's Z51 analog never moved off 220 (once it arrived there after warming up). The digital gauge might show 180 but the analog showed 220. The digital gauge might show 218 (the warmest I ever saw it) but the analog showed 220.
My '19 GS is different in that the analog gauge does seem to more accurately agree with the digital one

You were correct sir the analog gauge hit 220 before the digital gauge hit 165, the pic shows where it settled at. Thanks again.
