Adding coolant

The engine cooling system must be filled with a mixture of water, antifreeze and anti-corrosion agent G12. Additives to the coolant prevent defrosting of the engine block and the formation of corrosion and lime deposits, and also increase the boiling point of the coolant. Due to the fact that the cooling system is of a sealed type, when the coolant is heated, there is excess pressure in the cooling system, which also contributes to an increase in the boiling point of the coolant. The pressure in the cooling system is limited to 1.2–1.5 bar by a valve in the cap of the expansion tank.

When topping up the cooling system, even in the warm season, use only a mixture of antifreeze, anti-corrosion agent G 12 and clean water with a low lime content.
