What Causes the Engine Coolant High-Temperature Warning?
2 Answers
The reasons for the engine coolant high-temperature warning are as follows: The vehicle's prompt to check the coolant indicates a lack of coolant, which causes the engine to overheat. Additionally, poor grounding of the coolant pump, coolant pump failure, or excessive dirt in the radiator can also lead to this situation. Related to coolant level: In this case, it is necessary to check whether the coolant level is normal, whether the radiator fan is operating correctly, whether the radiator is severely dirty or clogged, and whether there is corrosion or poor contact in the coolant pump's grounding. Definition of coolant: Coolant, also known as antifreeze, is a liquid composed of antifreeze additives, additives to prevent metal corrosion, and water. It needs to have properties such as antifreeze capability, anti-corrosion, heat conductivity, and resistance to deterioration.
I drive quite frequently and have encountered the engine coolant high-temperature alarm several times, which almost scared me to death. The reasons are usually as follows: insufficient coolant, possibly due to a leak in the radiator or daily evaporation. The radiator can also get clogged, especially in winter when leaves fall in or dust accumulates, affecting the cooling efficiency. A non-functioning fan is a big issue, which could be due to a circuit failure or the fan blades being stuck. A thermostat stuck in the closed position is also common, preventing the coolant from circulating properly. A faulty water pump directly stops the liquid circulation. Ignoring the alarm may cause the engine to overheat and expand, leading to severe damage, such as a blown head gasket or deformation, which would cost a fortune to repair. I recommend checking the coolant level weekly to ensure it's between the MIN and MAX marks to avoid unnecessary trouble.
