What is Antifreeze?
[[File:Man pouring antifreeze.jpg|thumb|300px|Antifreeze is often poured into a car's [[radiator]] and [[windscreen]] washer bottle.]] '''Antifreeze''' is a [[liquid]] that lowers the [[freezing]] point of [[water]]. It is used to stop [[ice]] from growing on a [[surface]], like a [[windshield]]. It is also used inside pipes of a car's [[radiator]].<ref name=Ullmann>{{cite book|chapter=Antifreezes|first1=Sidney F.|last1=Bosen|first2=William A.|last2=Bowles|first3=Emory A.|last3=Ford|first4=Bruce D.|last4=Perlson|title=Ullmann's Encyclopedia of Industrial Chemistry |year=2000|doi=10.1002/14356007.a03_023|isbn=3527306730 }}</ref> As the temperature outside changes from hot to cold coolant is pumped throughout the engine block to maintain an even operating temperature. Antifreeze does more than just regulate temperature, however. Maintaining proper fluid levels also helps to prevent [[corrosion]].<ref>{{Cite web|title=WHAT IS ANTIFREEZE?|url=https://www.valvoline.com/our-products/antifreeze-products/antifreeze-education/what-is-antifreeze|access-date=2021-09-12|website=www.valvoline.com|language=en|archive-date=2021-09-12|archive-url=https://web.archive.org/web/20210912071931/https://www.valvoline.com/our-products/antifreeze-products/antifreeze-education/what-is-antifreeze|url-status=dead}}</ref> Engine coolant is mixed with water, usually at a 50/50 [[ratio]], and poured into the proper reservoir in your engine. The chemical [[ethylene glycol]] is used as a base to create a liquid that is pumped through your car’s engine to regulate and maintain an optimal operating temperature during extreme hot or cold weather conditions. ==References== {{reflist}} {{stub}} [[Category:Automotive technologies]] [[Category:Chemicals]]
