2. Waterless coolant - Wikipedia

   en.wikipedia.org/wiki/Waterless_coolant

   Waterless coolant is most prominently used in the cooling systems for motorsports, classic car, ATVs, UTVs, snowmobiles and older cars. [4] Older cars often have non-pressurized cooling systems, and the water-based coolant can boil and overflow. Traditionally, this issue has been solved by topping off the radiator with water. This dilutes the ...

3. Radiator (engine cooling) - Wikipedia

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

   Engine coolant is directed by the thermostat to the inlet of the circulating pump and is returned directly to the engine, bypassing the radiator. Directing water to circulate only through the engine allows the engine to reach optimum operating temperature as quickly as possible whilst avoiding localized "hot spots."

4. Internal combustion engine cooling - Wikipedia

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

   Comparing air and water, air has vastly lower heat capacity per gram and per volume (4000) and less than a tenth the conductivity, but also much lower viscosity (about 200 times lower: 17.4 × 10 −6 Pa·s for air vs 8.94 × 10 −4 Pa·s for water). Continuing the calculation from two paragraphs above, air cooling needs ten times of the ...

5. Water jacket - Wikipedia

   en.wikipedia.org/wiki/Water_jacket

   Water jackets were used to cool the barrels of machine guns until several years after the First World War, but modern machine guns are air-cooled to conserve weight and hence increase portability. In a reciprocating piston internal combustion engine , the water jacket is a series of holes either cast or bored through the main engine block and ...

6. Water cooling - Wikipedia

   en.wikipedia.org/wiki/Water_cooling

   Water cooling is a method of heat removal from components and industrial equipment. Evaporative cooling using water is often more efficient than air cooling. Water is inexpensive and non-toxic; however, it can contain impurities and cause corrosion. Water cooling is commonly used for cooling automobile internal combustion engines and power ...

7. Antifreeze - Wikipedia

   en.wikipedia.org/wiki/Antifreeze

   If plain water were to be used as an engine coolant in northern climates freezing would occur, causing significant internal engine damage. Also, plain water would increase the prevalence of galvanic corrosion. Proper engine coolant and a pressurized coolant system obviate these shortcomings of water. With proper antifreeze, a wide temperature ...

8. Wax thermostatic element - Wikipedia

   en.wikipedia.org/wiki/Wax_thermostatic_element

   Modern engines run hot, that is, over 80 °C (180 °F), in order to run more efficiently and to reduce the emission of pollutants. While the thermostat is closed, there is no flow of coolant in the radiator loop, and coolant water is instead redirected through the engine, allowing it to warm up rapidly while also avoiding hot spots.

9. Quad 4 engine - Wikipedia

   en.wikipedia.org/wiki/Quad_4_engine

   The Quad 4 is the first domestic regular production DOHC four-cylinder engine wholly designed and built by GM, the only similar prior example being the Chevrolet Cosworth Vega, whose DOHC head was designed by Cosworth in England. In addition to the 2.3-liter DOHC Quad 4s, there was also a short-lived 2.3-liter SOHC variant called the "Quad OHC ...
