Anti -freezing solution is called anti -freezer coolant，It means coolant with anti -freezing function。

Anti -frozen solution can prevent the cooling fluid frozen when the cooling fluid is frozen and the frozen engine air cylinder or lid。

Many people think that freezing solution is only used in winter，But in fact, the antifreeze must be used all year round。

General antifreeze is a ethylene glycol -type antifreeze，Ethylene glycol boiling point high，Freezing point low，Not easy to volatilize，Good thermal stability，Stable chemical performance，Therefore, it has been widely used。

In fact, the main component of the antifreeze will not change，The difference in color is mainly caused by the differences in the dyeing agent in the additive。

The specific reasons are as follows:

Differential antifreeze with different proportion，Because water and antifreeze seabet myare colorless，Anti -frozen solution with different ratio cannot be distinguished with the naked eye，So use different pigments，Division of it。

It can be clearly distinguished when the antifreeze is leaked，For example, the vehicle has a liquid leak，See the color，You can know if it is a non -frozen liquid leak，It also helps to easily find the missing point。

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

Prevent errors，See these colors，Everyone should pay attention，If there is no color，Easy to confuse water。

The answer is not.

Anti -frozen liquids of different ingredients or different colors must not be mixed，If you mix the antifreeze of different ingredients together，Anti -freezant will have a chemical reaction，Causes the anti -freezing fluid failure。

If the antifreeze is the same，Different colors，Can't mix，Anti -frozen liquid of different colors or different brands，The chemical composition of the additive is different，mixed，Chemical reactions may occur between multiple additives，Causes the additive failure。

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

Of course this is just a reference replacement cycle，Big can be replaced according to the actual usage，Because walking more than 10,000 or 20,000 kilometers or extension of the use cycle is more than one year and a half，The problem is not big。If the strength of the car is high，You can replace it in advance。

However，seabet loginIf you find that the size of the anti -freezer coolant is less than minimum (the normal capacity of the antifreeze coolant should be between min and max)，It is necessary to increase it in time，Otherwise it will affect the cooling performance of the engine。

If it is different from the last time it was added，So be sure to pay attention to cleaning up the last time，Then replace it。

When we are buying anti -freezing coolant，You can choose according to the minimum temperature of the area where you live，The freezing point of anti -freezer coolant is better than the lowest temperature of about 15 ° lower than the local minimum temperature，Make sure that when the weather is extremely abnormal, anti -freezer coolant strike。

At present, some anti -frozen coolant for "no need to replace" on the market，Compared with ordinary anti -freezer coolant，Their biggest advantage is that there is no need to replace the vehicle's lifetime use，Reduce trouble。For this product，Masters suggest that car owners still choose carefully。

In summer，Do not replace the antifreeze as other liquids such as tap water，This impact on the engine is very bad。

The normal work of the engine is inseparable from the auxiliary of the cooling system，For the engine cooling system, its key role is the anti -freezing coolant，Anti -freezing solution is an important medium for heat dissipation when engine work，But the function of antifreeze is not limited to this，There is also anti -rust、anticorrosive and other functions。
