Coolant — general information

Under normal operating conditions, the car's cooling system needs almost no maintenance. The coolant is formed by water, which contains 40% antifreeze. This mixture is not only frost-resistant down to -25 'C, but also protects the cooling and heating system of the car from corrosion. In addition, it prevents scale deposits and increases the boiling point of the coolant.

For this reason, it is impossible to reduce the concentration of antifreeze in the coolant by adding water, even not in the summer or when operating the car in countries with a hot climate. The concentration of antifreeze in the coolant must be at least 40%.

If in a cold climate you need increased frost resistance, then you can increase the concentration of antifreeze in the coolant, but only up to 60% (which corresponds to frost resistance down to about -40°C). Higher concentrations of antifreeze weaken the frost resistance and, in addition, the cooling effect worsens.

Attention.

• Some refrigerants can, first of all, significantly weaken the anti-corrosion protection.
• Corrosion damage can lead to coolant leakage and thus serious engine damage.
