Does Antifreeze Decrease Over Time?

[VanLila]

Antifreeze will naturally evaporate over time, leading to a reduction in volume. The full name of antifreeze should be antifreeze coolant, meaning it is a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing and expanding in cold winter conditions when the vehicle is parked, which could otherwise crack the radiator or damage the engine cylinder block or head. Functions of antifreeze: 1. Provides anti-corrosion protection for components of the cooling system; 2. Prevents scale formation, avoiding reduced heat dissipation efficiency of the radiator; 3. Ensures the engine operates within the normal temperature range. When antifreeze is insufficient, it directly affects the heat dissipation efficiency of the radiator. If the water temperature becomes too high, the red coolant temperature warning light on the dashboard will illuminate. Continuing to drive without turning off the engine may lead to engine seizure and damage.
