What causes the car to have no response when starting after overheating?

[StGriffin]

There are several reasons that can cause the engine's water temperature to rise excessively or even "boil over," such as damage to electronic components in the cooling system (thermostat, cooling fan), poor radiator performance, insufficient coolant, etc. Below is relevant information: 1. Causes: Damage to electronic components in the cooling system (thermostat, cooling fan), poor radiator performance, insufficient coolant, etc. 2. Solution: 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 right away would stop the circulation of the boiling coolant. Let the engine idle for a while first; the continuously circulating coolant can still mitigate the impact of high temperatures on the engine.
