In today's automotive industry, the selection and use of antifreeze is particularly important. As an important fluid that protects the engine, antifreeze prevents the coolant from freezing during the cold season and ensures that the engine's cooling needs are met in high temperature environments. In this article, we will introduce in detail the four key features of antifreeze: anti-freeze, anti-corrosion, water and scale, and high boiling point, so that car owners can better understand and choose.
· Antifreeze
The freezing point of various antifreeze is different, car owners need to choose according to the temperature environment of the region. The freezing point of the coolant should be lower than the lowest temperature in the region of about 10 ℃, in case of emergency, to prevent sudden changes in the weather lead to coolant icing, which in turn causes the water tank, the engine block expansion crack, freeze bad engine cylinder block. This feature is the most basic and critical role of antifreeze.
· Anti-corrosion
Antifreeze and engine block and water tank and other metal parts in contact, should have good anti-corrosion properties, to prevent rust and corrosion of metal parts, but also should have the role of preventing the aging of rubber parts. This can better protect the engine parts, extend their service life, to ensure the stable operation of the engine.
· Waterproof scale
Antifreeze should minimise the production of scale during the cycle to avoid blocking the circulating pipes and affecting the cooling system's heat dissipation function. Therefore, car owners in the selection and addition of antifreeze, should be careful to choose good quality products, to ensure that the antifreeze can effectively water scale, to maintain the cooling system unimpeded.
When adding antifreeze, car owners need to choose the right proportion of coolant according to the specific situation, and add it to the water tank, so that the liquid level reaches the prescribed position. It should be noted that in summer, do not use tap water instead of antifreeze, because tap water is easy to produce scale on the metal surface, affecting the engine's cooling effect, and in serious cases, even fatal to the engine.
· High boiling point
Coolant that meets the national standard, its boiling point is usually more than 105 ℃. This means that the coolant can withstand high temperatures without boiling, thus to a certain extent to meet the cooling needs of high-load engine cooling. This characteristic ensures that the engine can maintain normal operation even in a high temperature environment, and avoids failures and damages caused by overheating.
In summary, the choice and use of antifreeze is important to protect the engine and extend its service life. Vehicle owners should choose and use antifreeze reasonably according to factors such as the temperature and environment of the region, the type of engine and personal needs. At the same time, regular inspection and replacement of antifreeze is also one of the important measures to ensure the stable operation of the engine. I hope this article can provide useful reference and guidance for the majority of car owners.
