What is the reason for the car not starting after the water temperature is too high?

[EllianaMarie]

If the car does not start after the water temperature is too high, check whether the antifreeze is insufficient, which may cause the engine water temperature to rise. Also, inspect the coolant circulation to see if it is not flowing smoothly. Additionally, you can check components such as the water temperature sensor, water pump, thermostat, and cooling fan, as these may also lead to an increase in water temperature. Below is the relevant information: Here’s how to handle the situation: Pull over to the side of the road, but do not turn off the engine immediately. Since the coolant temperature is already very high and its cooling capacity has reached its limit, turning off the engine immediately will stop the circulation of the boiling coolant (for most engines, the water pump is driven by the crankshaft. Of course, engines with electric water pumps may fare better). The excessively high temperature will not be cooled, and the engine may struggle to withstand it.
