Antifreeze is a very important thing for cars. First of all, as the name suggests, antifreeze is a liquid that prevents the car's water tank from freezing, effectively preventing the expansion of the radiator and freezing the engine block or cover. In the winter, especially in the north, when the temperature drops to zero, it is very important to add antifreeze in time. What some riders don't know is that antifreeze in addition to antifreeze in winter, it also plays a role in preventing the boiling of the water tank. Antifreeze can increase the boiling point of water in the water tank. More than 100 degrees of water will not boil, which is very important for safe driving in summer. Some antifreezes are also added with anti-scaling additives, which not only prevent the scale from being generated in the water tank, but also have the effect of removing the engine scale that has already been produced. Antifreeze also has anti-corrosion function. The car cooling system is in contact with water at high temperature, which is prone to corrosion and rust. Automotive antifreeze also has anti-corrosion and derusting effects. Therefore, antifreeze is very important for cars. However, there are many kinds of antifreezes on the market, and the formulas are complicated, and the functions played by them are not the same. This is also the reason why we can see various colors of antifreeze on the market. Because of the different formulas, if you add different brands and different types of antifreeze, it is possible to offset each other and produce some bad chemical effects. In general, the ethylene glycol formula is green, the propylene glycol is red with orange, and the glycerol is blue. The chemical properties of different colors and different brands of antifreeze may vary greatly, and the composition is different. Nowadays, there are more ethylene glycol antifreezes on the market, and some are phosphates. If these two antifreezes are mixed, It produces a highly corrosive substance that can cause great damage to the engine. Ethylene glycol and propylene glycol react at high temperature and pressure to form a gum base. Therefore, antifreeze should not be added. Try to choose an antifreeze in one category (recipe color) to avoid unnecessary losses. To obtain perfect joins, inside of the solder ring copper fitting and the outside of the copper pipe are cleaned using coarse steel wool, flux paste is applied, the pipe is then inserted into the fitting and heat applied from a portable propane torch until a ring of solder shows at the edges of the fitting.
