My point is if you are dealing with it you have gone too far, one either gets that or they don't. Maybe many don't realize it and read it thinking they can rely on that saving them, definitely a mistake.
You need to realize how many engines I've changed for those who simply thought you drive it until it quits, then fix a small problem and continue for years more. The enlightenment (and repair bill) was not pleasant for them, if you get yours without having to buy new motor or car you should be thankful. ANYTIME you encounter temp at max you are risking the engine by continuing to drive it. Five minutes there is often certain death.
