Why is the coolant being used up quickly without any leaks?

[DeJames]

Reasons why the coolant is being used up quickly without any visible leaks: 1. Engine coolant is difficult to consume in large quantities without leakage. Therefore, when the coolant is being used up quickly but no leakage point is found, the possibility of coolant leakage cannot be ruled out. In this case, a more thorough inspection should be conducted to identify any hidden or hard-to-detect leakage points. 2. The engine temperature is too high, causing the coolant to break through the cylinder gasket's defense and enter the cylinder or oil passages. The full name of coolant is antifreeze coolant, meaning it has antifreeze properties. Antifreeze prevents the coolant from freezing and expanding during cold seasons, which could crack the radiator or damage the engine cylinder block.
