What are the signs of an overheating engine?

[DiBradley]

The signs of an overheating engine are: the water temperature needle on the vehicle dashboard exceeds the red mark, the water temperature warning light will illuminate, and sometimes white smoke may appear from the engine compartment. This indicates that the engine is overheating or there is insufficient coolant. It is recommended that the owner checks whether the radiator coolant is at the normal level, and whether there are any leaks in the radiator, radiator hoses, or other components. The causes of engine overheating include: leakage in the cooling system or insufficient coolant; inaccurate or malfunctioning water temperature gauge; excessive scale buildup in the cooling system, leading to poor heat dissipation; the radiator guard mesh or radiator core ventilation ducts being blocked by debris, resulting in poor heat dissipation; or the water pump and fan belt being too loose or broken.
