    Proper engine coolant and a pressurized coolant system obviate these shortcomings of water. With proper antifreeze, a wide temperature range can be tolerated by the engine coolant, such as −34 °F (−37 °C) to +265 °F (129 °C) for 50% (by volume) propylene glycol diluted with distilled water and a 15 psi pressurized coolant system.

    Car engine wax thermostatic element. The wax thermostatic element was invented in 1934 by Sergius Vernet (1899–1968). [1] Its principal application is in automotive thermostats used in the engine cooling system. The first applications in the plumbing and heating industries were in Sweden (1970) and in Switzerland (1971).

    On cooling, the compound becomes a light yellow metastable phase, which over 2–3 weeks turns back into original red. [8] Many other tetrachloronickelates are also thermochromic. Bis(diethylammonium) tetrachlorocuprate(II) ([(CH 3 CH 2 ) 2 NH 2 ] 2 CuCl 4 ) is a bright green solid material, which at 52–53 °C reversibly changes color to yellow.

  6. Oil cooling - Wikipedia

    en.wikipedia.org/wiki/Oil_cooling

    Oil cooling is the use of engine oil as a coolant, typically to remove surplus heat from an internal combustion engine. The hot engine transfers heat to the oil which then usually passes through a heat-exchanger, typically a type of radiator known as an oil cooler. The cooled oil flows back into the hot object to cool it continuously.
