What does low engine coolant temperature mean?

[JessicaLee]

Low engine coolant temperature refers to the coolant level being below the normal range. Coolant replacement cycle: The coolant needs to be replaced once a year. Coolant is characterized by a high boiling point and good stability, which can prevent scale formation in the radiator. Insufficient coolant will prevent the engine from cooling down in time, leading to excessive gaps between components and inability to function properly. Functions of coolant: Coolant, including glycerol-based coolant and ethylene glycol-based coolant, serves to cool down the engine. Also known as antifreeze, insufficient coolant cannot effectively cool the engine, leading to abnormal engine operation. Coolant can effectively prevent engine failures, avoid radiator overheating, and provide long-term protection for water temperature, making it suitable for year-round use.
