The full name of antifreeze should be called antifreeze coolant，means coolant with antifreeze function。

Antifreeze can prevent the coolant from freezing and cracking the radiator and freezing the engine cylinder block or cover when parking in cold winter。

Many people think that antifreeze is only used in winter，But in fact, antifreeze must be used throughout the year。

General antifreeze is ethylene glycol type antifreeze，Ethylene glycol has high boiling point，Low freezing point，Not easily volatile，Good thermal stability，Stable chemical properties，Therefore it has been widely used。

Seabet

In fact, the main components of antifreeze will not change，The difference in color is mainly caused by the different dyes in the additives。

The specific reasons are as follows:

Distinguish between different seabet myproportions of antifreeze，Because water and antifreeze are both colorless，Different ratios of antifreeze cannot be distinguished with the naked eye，So we use different pigments，Differentiate。

Be able to clearly identify when antifreeze is leaking，For example, there is a fluid leak in the vehicle，Look at the color，You will know if it is an antifreeze leak，Also helps to find leaks easily。

You can clearly see the consumption of antifreeze in the water tank，Add it in time，If it is colorless, it will not look so obvious。

Prevent accidental ingestion，See these colors，Everyone should pay attention，If there is no color，Easily confused with water。

The answer is no.

Antifreeze with different compositions or colors must not be mixed，If you mix different ingredients of antifreeze together，Antifreeze will cause a chemical reaction，causing antifreeze failure。

If the antifreeze is the same，Different colors，Cannot be mixed together，Antifreeze of different colors or brands，The chemical composition of additives is different，If mixed together，Chemical reactions are likely to occur between various additives，causing additive failure。

Most family cars are replaced every two years or 40,000 kilometers。

Of course this is just a reference replacement cycle，It can be replaced according to actual usage，Because the mileage is one or two million kilometers longer or the service life is extended by about one and a half years，Not a big problem。If you use the car intensively，You can replace it in advance。

However, the antifreeze seabet iocoolant has not been replaced yet，If it is found that the antifreeze coolant is less than the minimum scale value (the normal capacity of antifreeze coolant should be between MIN and MAX)，It will be added in time，Otherwise it will affect the cooling efficiency of the engine。

When replacing the antifreeze, if it is different from the one added last time，Then be sure to clean up the last one，Then replace。

When we are purchasing antifreeze coolant，You can choose according to the lowest temperature in the place of use，The freezing point of the antifreeze coolant is best about 15° lower than the local minimum temperature，Ensure that the antifreeze coolant fails when the weather is extreme and abnormal。

There are also some antifreeze coolants on the market that “no need to be replaced for life”，Compared to ordinary antifreeze coolant，Their biggest advantage is that they do not need to be replaced during the lifetime of the vehicle，Reduced trouble。For this product，Master advises car owners to choose carefully。

In use in summer，Do not replace antifreeze with other liquids such as tap water，This has a very bad impact on the engine。

The normal operation of the engine cannot be separated from the assistance of the cooling system，The key role in the engine cooling system is antifreeze coolant，Antifreeze is an important medium for heat dissipation when the engine is working，But the function of antifreeze is not limited to this，Also rustproof、Anti-corrosion and other functions。
