When it starts to puke fluid. If coolant is not boiling off, it won't hurt your engine. I like 180* for a driver. Good balance between HP and wear.

A good rule of thumb is staying above 240 degrees is considered overheating.

This applies to water and oil.

As long as it is not letting off steam or causing detonation.

yah water boils at 212 degrees and you have a coolant/water mix under pressure which won't boil till well over the 212 degree mark. If i was cruising and i saw 240 degrees on my temp gauge i would pull over and let my car cool down. i hate seeing 220.

If it aint blowing steam it aint overheating.

That said I like mine at 220 or less at idle on a hot day. Anything between 180 and 210 is about perfect.
