I've noticed that I have a different coolant gauge in my 2017 GLS450 than other 2017 GLS450's and even ones from 2018 and 2019. All of the ones I have seen have the coolant gauge without the temperature numbers shown and shows "H" and "C" instead (like in the second image i've attached), while mine has the temperature numbers shown (like the first image i've attached). Which gauge do you have and what is the reason that there were different gauges used for the same year? I personally prefer the one with the numbers a lot more.

I would much rather have yours than the c/h gauge.
Thanks for the pic. Its been super cold here (5 F) and my running temp is edging toward the 3rd bar. It's nice to have frame of reference.
The manual says that its expected under normal conditions to hit 120c, so I guess I don't have a problem.
