What are the models of antifreeze? What brand of antifreeze is good

Aqueous antifreeze for general use:

Its function is to increase the boiling point of cooling water, cool the engine, prevent corrosion of the cooling system, prevent scaling of cooling water, clean the cooling system and prevent foaming. When the engine temperature is above 80 degrees Celsius, water vapor is generated from the steel walls. The heat transfer of these water vapors is relatively poor, and it will slowly form a bubble layer in the peripheral metal of the cylinder, so that the heat in the engine cannot be dissipated in time, and over time it will produce scale, corroding the cylinder pipeline, water tank and water pump.

Waterless inorganic antifreeze.

To put it simply, inorganic antifreeze should not be mixed with water, while organic antifreeze can, as it contains water. Obviously, antifreeze without water will perform better than water, because the absence of water means a higher boiling point and a lower freezing point, and the inorganic additives contained in it can also prevent rust. Anhydrous antifreeze can indeed prevent corrosion, so that the engine will not "boil", and the volatility is weak, but it is not expensive, and it is good to say that luxury cars are used.

In addition, if you encounter a coolant leak, you can't directly add water for emergency, so you have to add it again, which is very troublesome.

When is the best time to replace car antifreeze? Mechanic: After this point, you may need to overhaul.

I just changed, the "Red Lover" of the Red Shell series, fifty or sixty yuan!

As long as it is antifreeze produced by regular manufacturers, it is okay, but the price of the brand is more expensive.

It must be a dragon crown, an old brand, and the general car decoration stores and supermarkets can sell it for about 30 yuan.

AntifreezeGood brands are: flauntingBMW, Kemitec, Valvoline, Awen.

AntifreezeThere is not much difference between models, and each manufacturer of antifreeze will have its own brand and model identification, unlike engine oil, which has a relatively certain model meaning.

However, the antifreeze will be clearly marked with a certain cautious front, such as low temperature (freezing point) temperature, or the low temperature applicable to the bucket changer, and the advantages and disadvantages of antifreeze are mainly reflected in the freezing point and boiling point.

First of all, in terms of the freezing point index of antifreeze, ordinary antifreeze can reach -40, and high-quality antifreeze should reach about -60. Secondly, in terms of the boiling point of antifreeze, the boiling point of water is 100, ordinary antifreeze can reach more than 108, and high-quality antifreeze should reach more than 110.

In other words, the lower the freezing point and the higher the boiling point of the antifreeze, the greater the temperature difference between the two, and the better the quality of this antifreeze.

Each manufacturer of antifreeze will have its own brand and model identification, unlike engine oil, which has a relatively certain model meaning; However, antifreeze will be clearly labeled, such as low (freezing) temperature, or applicable low temperature.

The main thing is that the freezing point is different, and the color is different, and the two cannot be mixed.

Generally, minus 35 must be used, and the color must be the same as the original car.

There is no model number to distinguish between color power.

The difference between antifreeze models: each manufacturer will have its own brand and model identification, and the main difference is to look at its freezing point and boiling point, the lower the freezing point, the higher the boiling point, the better.

The freezing point of antifreeze is 10 lower than the minimum temperature in winter in the place of residence, and there are roughly two types of antifreeze on the market, the first type is concentrate, which needs to be mixed with water. The second type is the "ready-to-use" type, and the antifreeze does not need to be mixed with water when it is used. In addition, vehicle manufacturers will also launch the original brand of antifreeze, which is generally concentrated and needs to be used with water.

Most of the "general-purpose" antifreeze on the market is mostly "ready-to-use" type, and the purchase is to choose the products of big brands as much as possible.

For southern car owners, the most important thing to pay attention to is the freezing point logo on the packaging. It is recommended to refer to the minimum winter temperature in the actual place of residence, and then drop it by 10-15 degrees Celsius. If southern car owners need to drive to the north in winter, then the choice of antifreeze needs to be based on the local weather conditions in Xiangconghu.

In general, it is no problem to choose an antifreeze suitable for -30-40.

Freezing point and boiling point are the most important factors in choosing an antifreeze. Pay special attention to the freezing point requirements, and generally use antifreeze 10 degrees lower than the minimum temperature. Secondly, pay attention to the boiling point of antifreeze.

Generally speaking, the boiling point of antifreeze is about 108, but the temperature of some engines can reach 110, so when choosing Tongzhao antifreeze, we should choose antifreeze with a higher boiling point.

Antifreeze prevents coolant from freezing when parking in the cold winter, which can cause the radiator antifreeze in the engine block to burst. The full name is Antifreeze Coolant.

There are many kinds of automotive antifreeze, such as calcium chloride (CaCl2) in inorganic matter, methanol (CH3OH) in organic matter, ethanol (C2H5OH, commonly known as alcohol), ethylene glycol (C2H4(OH)2, commonly known as sweet alcohol), glycerin (C3H5(OH)3, commonly known as glycerol), lubricating oil, sugar and honey, which are common in our daily life. Add an appropriate amount of purified soft water (water that does not contain or contains a small amount of calcium and magnesium ions, such as distilled water, unpolluted rainwater, snow water, etc.). , whose total hardness component concentration is between 0-30 ppm), it can be an antifreeze in the general sense.
