coolant flush

Waterless coolant is a glycol-based liquid substance that does not contain water. Its boiling point of 191 °C (375 °F) is higher than that of water-based coolants and it resists the formation of corrosion. The substance was invented to circumvent the problems of vaporizing water. When water vaporizes, it retains only 4% of its thermal conductivity. Water-based coolants are safe at temperatures below the boiling point of water to maintain the pressure of the system. Waterless coolant has environmental benefits, including reducing the use of cooling fans and therefore improving fuel economy. The coolant does not generally need changing, reducing the hazardous waste following repeated coolant flushes.
