Abstract: The invention relates to an aqueous anti-freeze agent containing 10 to 50 wt .% of one or several carboxylic acids, preferably aliphatic dicarboxylic acids with 4 to 12 C atoms in the form of the alkali metal ammonium or earth alkal i metal salt. The salts are applied preferably in combination with at least on e further substance. Anti-freeze agents with a good frost protection, good thermal conductivity and good corrosion protection are obtained.

Abstract: A method for cooling combustion engines involves using a circulating coolant fluid which contains non-ionic corrosion inhibitors and is at least intermittently deionized. Independent claims are also included for (1) a device for cooling combustion engines, comprising a coolant circuit (14) which is in thermal contact with the engine (11), and a de-ionizing device (28) in the coolant circuit (2) a liquid-cooled internal combustion machine with combustion engine(s) and coolant circuit(s) as above.
