What happens when you overheat a 928? Car ran well until it was overheated now it will not start.

I suggest changing the oil & oil filter first thing as the oil may be burned and no longer lubricate well. If coolant was lost it should be replaced.

Next, determine the cause of the no-start, like any other no-start. Is it no spark, no fuel, no/low compression etc.

Lastly, determine why there was an overheat condition. Were the cooling fans not operating (one fan in-op)? Was the coolant level low/a coolant hose leaking or broken?
