All the year round in the cooling system mix from water, the low-freezing and anticorrosive additives G11 VW is filled in. G11 interferes with freezing of cooling liquid, corrosion of the cooling system and a scum. Besides, increases liquid boiling temperature. In system of circulation of cooling liquid, thanks to its expansion when heating the excessive pressure promoting increase in a boiling point of cooling liquid is formed.
Pressure is limited to the valve in a carving cover of a broad tank which opens at 1,2–1,5 bars. Increase in a boiling point of cooling liquid is required for perfect operation of the cooling system of the engine. Too low boiling point can result in stagnation of heat at which circulation of cooling liquid is broken and cooling of the engine is broken. Therefore all the year round in the cooling system mix has to be filled in.
Only G11 or a concentrate with a mark can serve as additives "TL VW774A" is coordinated or "In".
