What are the reasons for the engine's inability to start after high-temperature shutdown?

[BethanyMarie]

Here are the reasons why the engine cannot start after high-temperature shutdown: 1. Insufficient coolant: Prolonged water circulation during engine operation can cause the coolant in the engine's cooling system to gradually deplete, leading to a lack of water in the radiator. If the owner fails to promptly inspect, detect, and replenish the coolant, this can easily result in engine overheating and the vehicle's inability to start. 2. Thermostat failure: The thermostat is a device that controls the flow path of the coolant. If it becomes stuck or fails, the engine's large and small circulation cycles will inevitably be affected, preventing the engine's heat from being effectively dissipated. 3. Exhaust issues: A blocked catalytic converter or a ruptured pipe can obstruct the engine's exhaust, leading to engine overheating.
