2. Antifreeze - Wikipedia

   en.wikipedia.org/wiki/Antifreeze

   An antifreeze mixture is used to achieve freezing-point depression for cold environments. Common antifreezes also increase the boiling point of the liquid, allowing higher coolant temperature. [1] However, all common antifreeze additives also have lower heat capacities than water, and do reduce water's ability to act as a coolant when added to ...

3. Ethylene glycol - Wikipedia

   en.wikipedia.org/wiki/Ethylene_glycol

   It's important to note that though pure and distilled water will have a greater specific heat capacity than any mixture of antifreeze and water, commercial antifreezes also typically contain an anti-corrosive additive to prevent pure water from corroding coolant passages in the engine block, cylinder head(s), water pump and radiator.

4. Coolant - Wikipedia

   en.wikipedia.org/wiki/Coolant

   A coolant is a substance, typically liquid, that is used to reduce or regulate the temperature of a system. An ideal coolant has high thermal capacity, low viscosity, is low-cost, non-toxic, chemically inert and neither causes nor promotes corrosion of the cooling system. Some applications also require the coolant to be an electrical insulator.

5. Waterless coolant - Wikipedia

   en.wikipedia.org/wiki/Waterless_coolant

   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 . [ 1 ]

6. Heat-transfer fluid - Wikipedia

   en.wikipedia.org/wiki/Heat-transfer_fluid

   Antifreeze additives can alleviate the freezing problem to some extent. However, many other heat transfer fluids have been developed and used in a huge variety of applications. For higher temperatures, oil or synthetic hydrocarbon- or silicone-based fluids offer lower vapor pressure.

7. Internal combustion engine cooling - Wikipedia

   en.wikipedia.org/wiki/Internal_combustion_engine...

   Most liquid-cooled engines use a mixture of water and chemicals such as antifreeze, rust inhibitors, and other additives. These antifreeze mixtures, also known as "engine coolant," are typically glycol-based fluids that contain a mixture of ethylene glycol, additives, and water. Common types of coolants include Inorganic Acid Technology (IAT ...
