Why shouldn't you pour regular water into the car's coolant tank?
Car coolant has a different structure and composition than regular water, so users should not use regular water to replace car coolant.
Car coolant is a specialized solution whose main ingredient is distilled water combined with ethylene glycol coolant (this substance has good heat conduction), along with other additives that help this solution to prevent evaporation, prevent scale and corrosion.
Many new car users often mistakenly think that coolant only cools engine parts, so they use regular water instead of specialized coolant.

However, regular water, mineral water, and filtered water are the types of water used in daily life. These types of water contain many compounds such as limestone, metals, and minerals. When exposed to high temperatures, they will cause sedimentation in the radiator. Using them for a long time will cause blockages, preventing the radiator from operating at full capacity.
Therefore, users should not use regular water to pour into the car's coolant tank to avoid reducing the cooling system's cooling efficiency.
However, in some emergency cases, it is necessary to use, for example in remote areas, where specialized coolant cannot be found, the driver can add regular water to the coolant tank so that the vehicle can continue to move. After that, it is necessary to quickly take the vehicle to a repair garage to clean, flush, rinse the radiator and pour in new coolant, ensuring the performance and durability of the vehicle.
