Why do you need to change the coolant?

Since these substances are constantly active during the operation of the cooling system, they lose their properties over time.

Although it is generally accepted that coolants are mixtures of glycol with distilled water, prepared in the right proportion, in addition to the listed ingredients, there are also very important additives.

These include, but are not limited to, anti-corrosion agents, formulations to prevent liquid foaming, ingredients to prevent cavitation, which destroys water pumps.

Therefore, for the sake of engine durability, it is necessary to change the fluid and pump the cooling system every 3 years.
