Why Does Car Antifreeze Decrease?

[DelCalvin]

Reasons for the decrease in car antifreeze: The protective additives in antifreeze experience certain depletion during engine operation. During engine operation, especially in summer when temperatures are high and heat dissipation is insufficient, the internal temperature rises, leading to some evaporation loss. It is necessary to replenish the antifreeze promptly to ensure proper engine cooling. Antifreeze prevents the coolant from freezing during cold seasons, which could otherwise cause the radiator to crack or damage the engine cylinder block. Antifreeze is not just for winter use; it should be used year-round. In regular car maintenance, the engine antifreeze should be replaced every year.
