Beschreibung
Zusammenfassung:	The invention relates to an anti-freeze concentrate having corrosion protection, suitable for coolants and heat carrier liquids, comprising liquids lowering the freezing point and organic compounds containing sulfur, inorganic salts molybdate, inorganic phosphate salts, inorganic phosphate salts and aliphatic, cyclo-aliphatic and aromatic mono-, di- or tri-carbonate acids. Aqueous coolant compositions can be obtained therefrom, which are suitable for cooling an internal combustion engine, the cooling device of which has been produced from aluminum by using a soldering method comprising a fluoroaluminate soldering flux.
