How is "dangerously high temperature" defined for a motor that is not running? What exactly is it that could cause temperature to rise once engine is stopped? No more fuel is being burned. The coolant may get warmer just where the temp gauge sensor is mounted but it (or the metal in the engine) has to have been that warm somewhere else already. I always thought the most danger as regards heat in a stopped motor was oil and seal damage in a turbocharger--what problems can occur in a 300E? I think that as long as pressure doesn't cause a leak, there may be little problem. Ideas?
