2011 LTZ with 62k miles. Was driving to work when I noticed the temp gauge at about the 245 mark. Immediately pulled over and the coolant reservoir was dry. Added a gallon of water on hand but that did not seem to even help at all. It came down to about 220 but red - lined about 1 minute later. Pulled over again, reservoir still full of water. I chanced it that it would come back down and pulled back onto interstate. No luck. Engine Hot A/C off indicator came on. I turned off the A/C because this indicator did not actually do it automatically. Temp returned to normal in 2 minutes. Turned A/C back on to see what would happen and the engine temp stayed normal. It did not go back up until I stopped the car at my destination.
Any idea? TIA
