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 ...
Butkus endorsed Prestone, a brand of antifreeze, in a commercial during Super Bowl IV in 1970. The ad marked the first highly successful celebrity endorsement in Super Bowl advertising . [ 101 ] Throughout the late 1970s and early 1980s, Butkus appeared alongside fellow former NFL star (and later Blue Thunder co-star) Bubba Smith in a series of ...
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.
An early sign of the need for replacement is the "Monday-morning smell" (due to lack of usage from Friday to Monday). Antiseptics are sometimes added to the fluid to kill bacteria. Such use must be balanced against whether the antiseptics will harm the cutting performance, workers' health, or the environment.
Mixing solvents creates cooling baths with variable freezing points. Temperatures between approximately −78 °C and −17 °C can be maintained by placing coolant into a mixture of ethylene glycol and ethanol, [1] while mixtures of methanol and water span the −128 °C to 0 °C temperature range.
A DuPont R-134a refrigerant. A refrigerant is a working fluid used in cooling, heating or reverse cooling and heating of air conditioning systems and heat pumps where they undergo a repeated phase transition from a liquid to a gas and back again.
A cryoprotectant is a substance used to protect biological tissue from freezing damage (i.e. that due to ice formation). Arctic and Antarctic insects, fish and amphibians create cryoprotectants (antifreeze compounds and antifreeze proteins) in their bodies to minimize freezing damage during cold winter periods.
1933 – Fokker Y1O-27, 31-601, '22', of the 32d Bombardment Squadron, Rockwell Field, California, during ferry flight from Rockwell to Brooks Field, Texas, pilot Capt. Albert F. Hegenberger, on leg between Tucson, Arizona and Midland, Texas, loses Prestone coolant out of starboard engine, engine temperature rises so he shuts it down. Forced ...
