Zusammenfassung:FIELD: cooling of internal combustion engines. SUBSTANCE: claimed method comprises adding cooling water components to substrate containing mixture of ethylene glycols and water mixture of ethylene glycols is prepared by hydration of ethylene oxide in liquid phase at ethylene oxide to water molar ratio in the presence of catalyst selected from cooling liquid components, and adding cooling liquid components to the resulting mixture. EFFECT: lower costs for preparing cooling liquid and improved properties of cooling liquid.
