For the Golf 6 model, the coolant is prescribed by the manufacturer, consisting of a mixture of antifreeze with a low freezing and water temperature. Its advantage is a relatively slight biological splinter after the end of use in a car. It is recommended to replace the coolant after three years of operation. In view of the fact that the cooling liquid contains additives that prevent the development of corrosion in cooling and heating systems, as well as the formation of mineral sediments, it must be used all year round.
The coolant concentration shall (also year round) so that the mixture is not frozen at temperatures up to -25 ° C. Consequently, the portion of the liquid with a lower temperature of hardening shall be not less than 40 per cent and not more than 60 per cent of the total volume (mixture 2: 3).
