I cant see pistons and injectors failing as part of over heating.
what are your thoughts?
The car was going up a mountain when the light came on and went off when going down. Could happen if going up quickly, high revs or lugging a lot of weight or the fans not working.
If the car drives, feels and sounds ok and has enough water apart from perhaps an oil change I am tempted to say leave alone. what are your thoughts?
I have asked what car they have and will add this to the thread incase it makes a difference.

Depending on height above sea level and how hard the car is working, I would suspect weak fuel mixture, followed or aggravated by a poor thermostat or clogged radiator fins. A top end overhaul would be right at the bottom of my suspects. I suppose injectors could play a part but simple diagnostic tests/codes would show the likelihood.
