How to make the car more “freeze-tolerant” in the severe cold season?[汽车修理知识]

Experience 1: Try to use the same brandantifreeze.

Different brands of antifreeze production formula will be different, if mixed use, a chemical reaction between various additives is likely to cause the additives to fail.

Experience 2: The validity period of antifreeze is mostly two years (some products will be longer), and it should be confirmed that the product is within the validity period when adding it.

Experience 3: It must be replaced regularly, usually every two years or every 40,000 kilometers.The old liquid should be drained when replacing, and thecooling systemAfter cleaning, replace with new liquid.

Experience 4: Avoid using with water. Generally, there are two kinds of antifreezes sold in the market: inorganic antifreeze and organic antifreeze. The former must not be mixed with water, otherwise precipitation will be formed and the normal function of the antifreeze will be affected. The latter can be used by mixing with water, but the proportion of mixing with water is strictly required for consumers to follow the instructions.

Experience 5: If the antifreeze is not used up, it should be stored in a plastic container, and it can be added when the antifreeze is lacking.

1.Choose antifreeze with different freezing points according to environmental conditions

At present, the freezing point of antifreeze on the market has several specifications, such as -15℃, -25℃, -30℃, -40℃, etc. Generally, it is better to choose the one that is more than 10℃ lower than the lowest temperature in the area. In winter, you should choose to use antifreeze with low freezing point. The lower the freezing point, the stronger the antifreeze performance of the antifreeze.

2.Choose antifreeze according to different requirements of vehicles

Permanent antifreeze (23 years) should be selected for general imported cars, domestic production line cars, and high- and mid-range cars. Ordinary cars can choose direct-use antifreeze.

3.Choose anti-corrosion, anti-rust and anti-freezing fluid with descaling ability

Anti-corrosion is the most important function of antifreeze, so it is best to choose brand-name products.Because preservatives, corrosion inhibitors, scale inhibitors anddetergent.Products that have not been formally inspected are often corrosive,carDamage to the cooling system, some antifreeze will alsoWater tankCorrosion and perforation flow into the engine, causing a major accident. Therefore, it is recommended that users choose a regular brand of antifreeze.
