What should I pay attention to when changing antifreeze in my car?

One: Do not add water to the antifreeze. When some riders see a lack of antifreeze in the water tank, they add tap water or "purified water". There are two hazards in this way: one is to reduce the freezing point of antifreeze, which will freeze the body in severe cold weather;

2. Pay attention to whether the replaced antifreeze is a fake or shoddy product.

3. Don't prepare your own antifreeze.

4. Don't change the antifreeze frequently. In general, the antifreeze should be replaced every two years, and frequent replacement will cause unnecessary waste.

5. If it is not replaced for a long time, the antifreeze ability of the antifreeze will be lost, and it should be replaced on schedule.

Before replacing, build a no-dismantle cleaning machine to clean the cooling system thoroughly, and then add high-quality antifreeze, and if necessary, add a bottle of cooling lubricant, so that the maintenance effect will be better.

Thank you!

If you replace the antifreeze in the car, you need to pay attention to the antifreeze in the engine before you need to release it, the freezing point of the new antifreeze must be lower than the local minimum temperature, the air must be exhausted after changing the antifreeze, and the water pipe must be glued and reinstalled after being removed.

Choose antifreeze with a low freezing point and a high boiling point. The main function of antifreeze is to prevent the inside of the engine from freezing when the temperature is too low in winter.

Choose one with good corrosion resistance. Many ordinary antifreeze only consider the freezing point and boiling point, and do not consider the ,.. corrosion protection

Replace the antifreeze and don't forget to flush the tank. When replacing the antifreeze, the original antifreeze should be fully drained and then replaced with a new one.

Do not mix different brands of antifreeze.

Choose a regular brand of antifreeze.

Antifreeze has a great protective effect on the engine of a car. But the name tends to make many people think that antifreeze is something that is only used in winter. But that's not the case, antifreeze should always be prepared.

Because for automobiles, antifreeze can not only prevent frostbite in the car, but also cool and dissipate some important parts of the car in the summer. Therefore, cars need antifreeze all year round, especially in summer, if the engine lacks antifreeze, it is easy to be damaged or even scrapped. In addition to maintaining the normal body temperature of our vehicles, antifreeze also has a certain degree of anti-rust, anti-mildew and other effects.

According to scientific calculations, antifreeze can be lost by about 20% in a year, and generally speaking, antifreeze will be replaced after two years of use or about 40,000 kilometers of our vehicles. However, if we find that there is less antifreeze during the daily inspection, we can also add it in time, and it is still important to replace the antifreeze. Because if we don't replace the antifreeze for a long time, then its shelf life may expire, and some of its related functions may also be reduced.

However, when changing the antifreeze, we must pay attention to the fact that the antifreeze cannot be mixed. In fact, experienced people should find that there are many colors of antifreeze. Because there are many brands of antifreeze, the additives of each antifreeze are different.

If we mix multiple antifreezes, it can cause damage to our car engines.

In addition, we should not fill the antifreeze with water, because the minerals in the water may make the antifreeze function ineffective. Antifreeze comes in different colors, and in addition to the fact that they have different additives, there are also some differences in the content of the same elements. In order to increase their rust prevention function, some antifreeze will add some more metal elements.

Therefore, when buying antifreeze, we must pay more attention.

It should be when the car can't drive at all and the ambient temperature is relatively low.

That is, when the antifreeze of the car will not have any effect, we need to replace it at this time, otherwise it will have a serious impact on the car itself.

If the landlord of the car is gone, or there are some problems with the performance of the car, it is necessary to replace the antifreeze in time. In addition, if the car continues to be high and does not drop, it also needs to be replaced.

As an antifreeze coolant, car antifreeze has antifreeze function, anti-corrosion function and anti-scale function, and antifreeze can prevent the car from being damaged by the weather in winter or summer.

It is really necessary to pay attention to the fact that the antifreeze generally fails or there are many things to pay attention to when replacing the antifreeze, among which we must know that the antifreeze is an inherent liquid, and the water and oil used at ordinary times can not be mixed with the antifreeze. At that time, it is not only the antifreeze body itself that will be damaged, but also the entire car.

It should also be noted that when replacing antifreeze, you must always maintain the same brand of antifreeze, if you replace different types of antifreeze at any time, it will also damage the antifreeze body, and even use some fake and shoddy products as a replacement for antifreeze, it will also directly damage the antifreeze body, but also pay attention to remember that you can't configure antifreeze by yourself, there are many drivers who choose to configure the corresponding antifreeze after observing the instructions on the antifreeze bottle, which is not right, because there is no professional proportional configuration, Even antifreeze that is not equipped with the device will not work.

As a protective film of the fuselage, antifreeze must pay attention to the dynamics of antifreeze for a long time, after all, once the antifreeze fails, it will not have the corresponding effect if it is not replaced in time, and the fuselage will be corroded or even fall off because of the absence of antifreeze. Therefore, the antifreeze should be paid attention to at any time, and the antifreeze should be replaced regularly for a long time. However, it is also important to remember that the antifreeze should not be replaced frequently, and the general antifreeze replacement is about once every two years, if the antifreeze is changed frequently, in addition to causing necessary waste, the antifreeze will not work.

First, don't add water to the antifreeze. Second, perform a thorough cleaning of the system before replacement. Third, pay attention to whether the antifreeze has passed its expiration date. Fourth, don't change the antifreeze frequently. Fifth, it should be replaced on a regular basis.

The first point is to pay attention to whether the car can be started, the second point is to pay attention to the cleaning of the whole car is very important, and the third point is to pay attention to the antifreeze water when you just change the antifreeze, you should pay attention to the cleaning.

In fact, you should grasp the amount of antifreeze, and you can also choose a better product.

Also remember that it is best to use the same brand of antifreeze, if you drain the old antifreeze according to what I said above, it doesn't matter, it doesn't matter if you use any brand of antifreeze, as long as it meets the requirements, some brands of car exhaust air need to be operated by computer, this can only go to the 4S store to replace, can not be replaced by yourself.

Antifreeze can not be mixed, if different types of antifreeze are mixed, it is easy to have chemical reaction, precipitation or foaming, so that the antifreeze anti-corrosion, anti-scaling, anti-boiling, anti-freezing, anti-rust and other effects will have a greater impact.

Car coolant, the full name is antifreeze coolant, for southerners may not have enough experience with this antifreeze. So there is not much difference between adding more than 0 degrees or above -40 degrees, but for the north, the difference between the two is big. It is likely that the north will reach minus 40 degrees, and the operation is cumbersome.

First of all, open the radiator cover (water tank cover) to relieve the pressure of the cooling system, this is similar to the method of changing the oil, open the cover can speed up the discharge of antifreeze, and when replacing the antifreeze, the original antifreeze in the engine should be drained clean.

Do not add water to antifreeze. When some riders see a lack of antifreeze in the water tank, they add tap water or "purified water". There are two harms to this:

One is to reduce the freezing point of antifreeze, and it must be noted that the body will be frozen in severe cold weather, but that is for professionals or people with strong hands-on ability, if you don't know much about car maintenance, then you should go to the repair shop to replace it, after all, the money is not much saved, and in the end, it will be worth the loss if you burn yourself!

It is recommended to use the antifreeze for two years or 50,000 kilometers to replace, and if the antifreeze is not changed for a long time, the antiseptic ability will decrease, the color will be black, and the freezing point of the antifreeze replacement should be in line with the local climatic conditions. Then idle for 3 to 5 minutes to allow the water to circulate. The water that starts to flow out of the pitcher is a little pink, and continue to pour in clean water until the water that comes out is clean.

Don't forget to remove the warm air water pipe and drain the water from the warm air tank.

The bottom bracket is named because it has five connections that connect various parts, and the antifreeze must flow through the bottom bracket and then be distributed to different parts of the car to function. So before replacing the antifreeze completely, first do a full inspection to look at the individual pipes and the antifreeze is not used only in winter, but throughout the year. Because it not only protects against freezing, but also increases the boiling point, which is especially important in the summer, otherwise the car will have to "boil" after a few kilometers of driving.

When replacing it, you must pay attention to the way and method, and you should also find the location of the antifreeze, and it should also be fast, and then quickly close the lid of the antifreeze.

When replacing the antifreeze, you need to drain the previous antifreeze and then replace it, if it is not discharged, this will affect the quality of the antifreeze.

When releasing antifreeze, it must be done cold-down to prevent burns. It is also necessary to disassemble the upper and lower water pipes at the same time and release them together to avoid unclean storage.

Be sure to do a full inspection to see if there are any traces of leakage in your pipes, and be sure to change the antifreeze, and the viscosity of the antifreeze is not too large.

The previous one should be completely replaced, and it should also be ensured that there are no traces of leakage after the replacement, and it should also be checked for some cracks.

The antifreeze for the engine is also known as coolant, and the process and steps for replacing the antifreeze are much the same. The steps to properly replace the antifreeze are as follows:1

Prepare tools and materials. Includes tongs, buckets with antifreeze, and antifreeze (4L). 2.

Drain the original antifreeze. Be careful not to replace it when the engine is hot, you need to open the radiator cover first, release the pressure, open the water tank cover, and then drain the antifreeze. If there is an engine shield on the chassis of the vehicle, you need to remove the shield first, then turn on the drain switch under the radiator and unscrew it clockwise.

3.Add a new antifreeze. The vehicle can be lowered and the radiator cover can be filled with antifreeze until the antifreeze flows out of the radiator opening.

Then open the exhaust bolt, exhaust the air bubbles, add antifreeze, close the radiator cap, increase the engine speed to 2000r min, stare at the bending pin and add liquid in the reservoir until it is close to the MAX scale line, and finally let the engine cool naturally. 4.Stay safe.

Before lifting the vehicle, you need to check that the handbrake is tightened and hung on the P or N gear. When working, you need to wear gloves to avoid contact with antifreeze. **Antifreeze should be treated as industrial wastewater.

Clean the cooling system after replacing the antifreeze to avoid mixing the old and new antifreeze and causing the new antifreeze to fail. When changing antifreeze, you need to follow the correct steps to ensure safety and avoid the engine temperature from being too high and affecting the normal operation of the engine. At the same time, it is necessary to clean the cooling system after replacing the antifreeze to avoid the failure of the new antifreeze caused by the mixing of the old and new antifreeze.

<> "In winter, because the temperature is relatively low in the tomb, in order to prevent the engine and water tank from being affected by freezing, we must pay attention to the use of antifreeze, because antifreeze has a certain service life, so we should pay attention to timely change.

Before replacing the antifreeze, you should do an inspection to see if there are cracks and traces of leakage in each pipeline, and if there is a leakage of antifreeze, it should be replaced in time according to the situation.

Wash the liquid passage with clean water and drain the old antifreeze. Just add clean water to the antifreeze refill tank, fill the tank with clean water, make the water flow continuously through the engine cooling system, and then idle the car for 3 to 5 minutes to let the water circulate. The water that starts to flow out of the jug is a little pink, continue to pour in clean water until the water that comes out is clean, and that's it.

At the same time, the warm air water pipe should be dismantled, and the water from the warm air tank should be discharged.

Add the new antifreeze through the water pipe of the radiator, let the antifreeze flow into the water tank quickly, and also fill the antifreeze tank with antifreeze, start the car, about 10 minutes, the cooling system can be partially air-drained, at this time the liquid level should drop a little, and then add the antifreeze to the highest mark of the reservoir"maxt"That's it.

It is necessary to know that freezing point and boiling point are the basic indicators of antifreeze, and they must have the characteristics of antifreeze, let go of the pot, anti-corrosion, waterproof scale, and no foam.

Therefore, it is best for car owners to use antifreeze all year round, which is beneficial to the engine, and can also reduce the generation of scale, which will adversely affect the heat dissipation of the engine, so car owners, for the health of the car, or use antifreeze.
