2008 Ford E-250: Engine Coolant/Antifreeze
*** Relevant Background : " Most automotive engines are "water"-cooled to remove waste heat , though the "water" used is actually a mixture of water and antifreeze. The term engine coolant is widely used in the automotive industry, which covers its primary function of convective heat transfer for internal combustion engines . When used in an automotive context, corrosion inhibitors are added to help protect vehicles' radiators , which often contain a range of electrochemically incompatible metals ( aluminum , cast iron , copper , brass , solder , etc.). Water pump seal lubricant is also added. 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 ...
