Is the engine really overheating or does the gauge tell you that the engine is overheating?
FYI: the water temperature sensor is located at the RH bank. A (hot) air bubble may get stucked at the sensor while circulating in the water and make it show an incredibly high temperature in the instrument cluster.
This happens because air has a much lower thermal inertia than water, therefore air gets hotter than water in the same amount of time.
So the gauge will tell you that engine is overheating, but the otterstat won't trigger the fans because the engine is not really overheating.
It has happened to me the first day I took it out from the box once driven home in 2009.
