I have a '06 GTP (3.9) I was wondering what the normal operating temp usually runs? I've attached an image of what mine always runs. Few of my friends told me this is too high and I may need a new thermostat.. but wanted to ask here first. Is this a normal temp? Not sure if mileage would play any part, but shes running just over 190K

That is where mine sits.
New thermostat and radiator maybe 9 mths ago. Heavy, slow traffic or heavy grades here in the Rockies, I might cycle up to around that 225 mark, but that's on a really tough day.
That scale is not really helpful either.
Numerically, the lines sit at:
100
131.25
162.5
193.75
225.
So a tick over the third line is 195ish.

I have the same car, ‘06 G6 GTP. Mine runs steady in the same spot. I’d say it’s fine.

That's where it should be. I have a ScanGauge II hooked up so I can see the actual temp. Sits around 195'ish with small fluctuations.
