what is best antifreeze for cars?
Suitable antifreeze engine coolant, or engine coolant, is a colored liquid mixed with water to help regulate your engine at low or high temperatures. As the outside temperature changes from hot to cold coolant is pumped throughout the engine block to maintain an even operating temperature. However, antifreeze goes beyond temperature regulation. In addition to maintaining proper fluid levels, proper antifreeze also helps prevent corrosion. The most basic substance that makes it work well in very hot or cold weather is ethylene glycol, which is mixed with water at a ratio of 50-50 and poured into a suitable tank.
Why do cars need antifreeze?
Antifreeze is a liquid that is added to water in order to lower the freezing point in the engine cooling system. This means that under normal cold weather conditions, water does not freeze. The freezing of water in the car engine causes serious damage to the radiator and other components, which requires energy and high cost to compensate for the resulting damages. The right antifreeze is a smart substance that stops water from freezing or boiling in your engine’s cooling system. In addition, it can turn it into a vital car fluid to make your engine run smoothly. In addition to preventing water from freezing, this substance increases the boiling point of the engine coolant to prevent overheating. These materials also protect your engine from corrosion, aid in heat transfer, and prevent internal deposit build-up.
What makes antifreeze different?
The base material of all cooling materials in green, pink or orange colors is ethylene glycol. What makes the antifreezes different are the additives and colors, pink and orange antifreezes are designed for use in vehicles that cover longer distances, while green antifreezes have a more general formula and have been used worldwide for a long time. have. Green coolant is a common coolant based on ethylene glycol and is the most common type of coolant available. In addition, due to the wide range of types of machines, it is necessary to have different types of antifreeze available that both establish temperature balance and prevent corrosion, for example, diesel engines need different antifreeze properties than gasoline engines. Diesel engines experience very high temperatures and therefore the antifreeze boiling temperature must be very high. And the cylinder wall corrosion is high in these engines, therefore, to prevent corrosion, they need antifreeze with additional additives to prevent corrosion
There are generally two types of antifreeze
The first type is the concentrated form and the second type is antifreeze mixed with water. The second version is usually referred to as engine cooling and can normally be used for charging and switching. The concentrated form should usually be diluted to a ratio of about 50% antifreeze and 50% water, but always check the directions for the proper ratio to use as a precaution. Many modern cars manufactured after 1998 require antifreeze that uses silicate-free organic acid (OAT) technology. Older cars usually require a more conventional type of antifreeze that is not OAT based and contains silicates. Engine coolant is usually mixed 50/50 with water and poured into the appropriate reservoir for your engine. Ethylene glycol chemicals are used as the base to create the fluid that is pumped through your car’s engine to maintain and maintain optimal operating temperatures in extreme hot or warm weather conditions.
What is the difference between the best antifreeze suitable for different cars?
All coolants are made from ethylene glycol based chemicals. Although antifreezes are produced in different colors such as green, pink or orange, but the basis of all of them is the same. For example, what makes the antifreeze/coolant difference are additives and colorants designed for use on a variety of higher mileage vehicles, while green is a more generic form that has been around for decades. The world is used.
Classification by color
Red coolant is usually based on Acid Organic Technology, which has a different chemical composition than green coolant and is designed to be suitable for aluminum radiators. Red coolant is often silicate and phosphate free for use in Japanese vehicles.
Blue coolant is usually an organic acid base, and what makes it different from red coolant is that it typically does not contain the borate that is used in modern Japanese vehicles.
Yellow or orange coolers are the latest technology and a universal product. Some universal coolers allow mixing to a certain extent of the total capacity of the cooling system.
What is the proper antifreeze made of?
Most antifreezes are made by mixing distilled water with additives and MEG (monoethylene glycol) or MPG (monopropylene glycol) as a base product.
Ethylene glycol
Ethylene glycol solutions became available in 1926 and were marketed as “permanent antifreeze” because the higher boiling points provided advantages for use in summer as well as in cold weather. Today they are used for a variety of applications including automotive, but there are less toxic options available with propylene glycol. When ethylene glycol is used in the system, it may oxidize to five organic acids (formic acid, oxalic acid, glycolic acid, glyoxalic acid, and acetic acid). Ethylene glycol inhibited antifreeze mixtures are available with additives that buffer the pH and alkalinity of the solution to prevent oxidation of ethylene glycol and the formation of these acids. Nitrites, silicates, borates, and azoles may also be used to prevent corrosive attack on the metal. Ethylene glycol has a bitter, sweet taste and causes burning. The toxic effects of ingesting ethylene glycol occur because it is converted by the liver into 4 other chemicals that are much more toxic. The lethal dose of pure ethylene glycol is 1.4 mL/kg (3 US fluid ounces (90 mL) is lethal to a 140-pound (64 kg) person), but is much more lethal if treated within an hour.
