  2. Antifreeze - Wikipedia

    en.wikipedia.org/wiki/Antifreeze

    Antifreeze was developed to overcome the shortcomings of water as a heat transfer fluid. On the other hand, if the engine coolant gets too hot, it might boil while inside the engine, causing voids (pockets of steam), leading to localized hot spots and the catastrophic failure of the engine. If plain water were to be used as an engine coolant in ...

  3. 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.

  4. Internal combustion engine cooling - Wikipedia

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

    Only the fixed parts of the engine, such as the block and head, are cooled directly by the main coolant system. Moving parts such as the pistons, and to a lesser extent the crankshaft and connecting rods, must rely on the lubrication oil as a coolant, or to a very limited amount of conduction into the block and thence the main coolant. High ...

  5. Radiator (engine cooling) - Wikipedia

    en.wikipedia.org/wiki/Radiator_(engine_cooling)

    Antifreeze itself is usually ethylene glycol or propylene glycol (with a small amount of corrosion inhibitor). A typical automotive cooling system comprises: a series of galleries cast into the engine block and cylinder head, surrounding the combustion chambers with circulating liquid to carry away heat;

  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. 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 ]
