![]() Silica is not only very abundant in the earth, it also has many uses. Silica comes in three main forms: cristobalite, quartz, and tridymite. The compound is known in chemistry terms as SiO2. In fact, 59% of the Earth’s crust is made of silica and it is also abundant in beach sand. Silica is one of the two most abundant elements found in the Earth’s crust. ![]() The chemical is widely classified as a salt of various types of silicic acids. Silica, or silica dioxide, is a chemical compound made up of silicon, one or more metals, and oxygen. Adding coolant only becomes necessary when there are problems in the cooling system that can cause a loss of coolant. When the vehicle is serviced, the technician will check the coolant levels in the radiator and reservoir. The passageways could be blocked, or there simply is not enough coolant running through the system to keep everything cool. The engine may overheat due to a lack of antifreeze or from antifreeze leaks or not circulating. When the coolant has air, it does not absorb heat from the engine the same way. The engine gets extremely hot and forces the liquid out. If temperatures under the hood get hot enough, the coolant will start to evaporate. The engine requires consistent flows of coolant. The primary job of antifreeze is to keep things cool. The coolant then returns back to the engine and the process starts all over again. Natural air coming in from the grill cools the antifreeze as it passes through the radiator. ![]() The heated coolant travels through rubber hoses to the radiator. The antifreeze then travels through the parts of the engine, absorbing the heat. A water pump circulates the antifreeze through those passages, which is moved around by hoses and cooled in the radiator. There are passages in the engine block and also in the engine heads. Thus, internal combustion engines have cooling systems with a mix of ethylene glycol antifreeze and water that is designed to prevent freezing, overheating, and buildup. No one wants their engine to freeze or overheat. By 2004, Prestone had introduced an antifreeze that would work in any car or light-duty truck. In 1977, Super Fluch was added to the antifreeze to prevent rust and scale. As the design of the automobile began to evolve to more sophisticated design, antifreeze has also evolved. The company also pioneered nonflammable antifreeze. In 1961, Prestone introduced Long Life Coolant which was designed to specially cool the metals under the hood. In 1944, Prestone antifreeze was used to keep the US military vehicles cool in extreme conditions. The goal has been to protect vehicles from the harsh effects of time and environmental conditions. The coolant (view on Amazon) is a mix of ethylene glycol antifreeze and water that are designed to remove heat from the engine. ![]() Some would even say that Prestone pioneered antifreeze. Prestone has produced coolant/antifreeze since 1927. Your Need to Know This About Your Coolant.Does Prestone Antifreeze Contain Silica?. ![]()
