How long can a car run with overheating coolant before the engine seizes?

[Harmony]

Driving 1-2 kilometers with overheating coolant may cause engine seizure, and in severe cases, the engine may be completely damaged. Common causes of overheating include: 1. Insufficient coolant; 2. Radiator leakage; 3. Cooling fan malfunction; 4. Thermostat sticking or failure; 5. Water pump damage. Solutions for overheating coolant: 1. Check the temperature difference between the upper and lower radiator hoses; 2. Inspect the thermostat opening and whether the water pump has speed loss issues; 3. Use high-pressure air to thoroughly clean dust between the condenser and radiator; 4. Use genuine parts when replacing or adding antifreeze; 5. Check the return flow in the coolant reservoir's upper return hose.
