Hi, Checked for history of codes, none found, Gauge never goes over 190, i keep an eye on it lately, since i got the mesage, Had issues where one of the GMLAN wires were chaffed, that got fixed.

Hi, Has anyone gotten a message " Idle Engine to cool Engine" I've seen it a few times, it pops on an then off, it doesn't really stay on for any length of time, it just dings, and goes away. I looked at the water pump, no leeks that i can see, and I don't see any coolant under. Any one come across a similar message? any idea's?
