What is the sign of engine overheating?

[LaMargaret]

Engine overheating signs: The water temperature pointer on the vehicle dashboard exceeds the red mark, the water temperature warning light will illuminate, and sometimes white smoke may appear in the engine compartment. This indicates that the engine temperature is too high or there is insufficient coolant. It is recommended that the owner check whether the radiator coolant is normal, and whether there are leaks in the radiator, cooling hoses, and various components. The causes of engine overheating include: leaks in the cooling system or insufficient coolant; inaccurate or malfunctioning water temperature gauge; excessive scale in the cooling system, leading to poor heat dissipation; blockage of the radiator guard mesh or radiator core ventilation ducts by debris, resulting in poor heat dissipation; loose or broken water pump or fan belt. Measures to prevent engine overheating: Ensure sufficient coolant; check whether the thermostat is functioning properly. If the thermostat fails to open the main valve promptly as required, it must be replaced immediately. If a replacement cannot be obtained in time, the thermostat can be temporarily removed, but a faulty thermostat should never be left at the water jacket outlet; park the vehicle in a shaded area.
