Abstract
A coolant recycling apparatus has a boiler and condenser for distilling a glycol and water from a used coolant. The glycol and water are recombined in a mixing tank to form a mixture having a desired ratio of water to glycol, and an inhibitor is added to the mixture to obtain a fresh coolant mixture ready for use in an engine cooling system. Contaminants in the used coolant are concentrated to form a sludge.
