Antifreeze is a must for our car, but I also agree that a place that is overlooked, many people have many misunderstandings about the use of antifreeze.
Antifreeze is only needed in winter?
Many people think that the role of antifreeze is to prevent frost, so only the cold winter needs antifreeze, but this is not the case, antifreeze is actually needed all year round. The full name of antifreeze should be called antifreeze coolant. In addition to preventing the coolant from freezing and expanding in cold weather, the antifreeze can damage the radiator and freeze the engine cylinders. In the summer, it can be boiling-proof, and daily use can be waterproof and scale-proof, rust-proof, anti-corrosion, and lubrication.
Does antifreeze have a shelf life?
Automobile manufacturers do not produce antifreeze, so all the original antifreeze is purchased by car companies, antifreeze is of good quality, most of the antifreeze 3 years or 60,000 kilometers to be replaced, and is the first to come prevail. Each brand of antifreeze may be slightly different, so please refer to the replacement cycle specified in the vehicle manual.
What happens if the antifreeze expires and is not changed?
Here to remind everyone, antifreeze is a chemical agent, any chemical preparation has a shelf life, expired antifreeze first of all is the winter can not play the effect of antifreeze, easy to cause damage to radiators and cylinders. Secondly, the summer can not play a boiling effect, the water tank is easy to boil and open the pot, resulting in engine damage. Finally, daily use can lead to corrosion of waterways.
Can I replace the antifreeze with purified water when it expires?
Many self-proclaimed old drivers who know how to understand cars often think of some cost-saving "tricks" and ridicule others for spending money unjustly, such as replacing glass water with detergent water and pure water instead of antifreeze. But antifreeze is such an important thing, pure water can replace? The boiling point of water is 100 degrees, the freezing point is 0 degrees, and you are really a talent to replace antifreeze. Pure water instead of antifreeze, not antifreeze in winter, not anti-boiling in summer, and will also produce a lot of scale to block the pipe.
There are so many antifreeze colors, how to change?
The antifreeze on the market is colorful, how should it be replaced? The antifreeze itself is colorless, and colorants are added for easy identification. In general, blue represents glycerol, green represents ethylene glycol, and pink represents propylene glycol. At present, most of the water-based antifreeze of ethylene glycol is used on the market, and ethylene glycol is antifreeze, good volatility, moderate viscosity, high boiling point, and good thermal stability, so it is very suitable as antifreeze.
When replacing, it is recommended to replace the same brand of antifreeze with the same color as the original factory, because two different antifreeze are mixed, because of the different chemical compositions, it is easy to produce chemical reactions. If you have to replace other antifreeze, it is recommended to suck out the antifreeze in the waterway and replace it thoroughly.
Although the antifreeze is small, it is very important for our daily use of the car, and the small antifreeze, there is a lot of learning, do not be sloppy.
