If the car changes the coolant, does it have to use the original factory?

That's right. OriginalAntifreezeThe quality is more reliable, and it is recommended that you go to the 4S store to replace the original antifreeze. If you buy other brands, you need to pay attention to the products of regular manufacturers.

Some of the cheap "antifreeze" on the market is made with ethanol.

It is mixed with water and made with the addition of coloring, without adding any preservatives that antifreeze must have.

Additives such as scale inhibitors, with a boiling point of about 90, are highly corrosive and can easily lead to engine overheating.

The simple way to distinguish the authenticity of antifreeze is as follows: high-quality antifreeze is eye-catching, clear and transparent, and has no peculiar smell, heat the antifreeze with a beaker, and measure its boiling point with a thermometer, where the boiling point is less than 100.

The antifreeze model is generally its freezing point value, and the purchase reference value in different regions should be different, the original antifreeze model of -25 can be used in the south of the Yangtze River throughout the year, and the water tank coolant with a freezing point value of -15 can also be used in some areas. The area north of the Yangtze River, the northeast region.

and the northwest region should use -35 -50 original antifreeze.

Note: Different manufacturers and different models of antifreeze cannot be mixed.

Now there are many brands of anti-coolant on the market, and the various formulas are not the same, Jianyi landlord uses coolant (antifreeze) suitable for all models.

I heard from the master who has been repairing for many years that the new car No. 1 can be tried, which is suitable for all models.

Hello! You don't have to use the original factory to change the refrigerant in the car! It is recommended to change to Meifu brand antifreeze!

Hello! No, choose a good brand of antifreeze. Castrol, Caltex and Shell antifreeze are fine, as long as the color is the same, it is no problem.

Hello! No! You can choose a big brand of coolant such as Total! Hope it helps.

No, you can exchange it for something else. According to the temperature change of the location, you can choose the appropriate freezing point. You can pay attention to Dingdong car butler and consult car butler.

Hello, as long as the color is the same and the freezing point is right,

You don't have to use the original factory, you can choose the brand.

Car coolant does not need to be replaced, and it can be added less.

Coolant, also known as antifreeze, antifreeze, water tank treasure, etc. The main function is to protect the normal and good operation of the engine, circulating in the engine water tank, playing the effect of anti-freezing, anti-boiling, anti-rust, anti-corrosion, etc., most of the antifreeze is red or green in color to observe whether it leaks, or distinguish it from other liquids of the engine, to avoid confusion.

Engine coolant, the common one is glycol-aqueous solution, which is the basis. Due to the requirements of modern automotive processes, many additives are added to the coolant to protect a wide variety of engines. The difference in these additives causes the coolant to diverge into several camps.

OAT Camp:

The representative product is the well-known DEX-COOL coolant. There are also Volkswagen's G12 (BASF OEM), GM's general loading coolant, and Caltex special antifreeze and anticorrosive liquid in the retail market.

Organic acid coolant does not contain silicon, amine, boron, phosphorus, nitrite and other substances harmful to the human body or the environment, and organic acids are not easy to consume and decompose, so they can maintain a relatively long life, OAT is a long-term coolant, recommended replacement cycle of 5 years or 25WKM.

Japanese coolant:

Coolants used in Japanese cars are unique, but they generally contain phosphates, which are harmful to the environment. Japanese models absolutely reject silicate and nitrite additives. The vast majority of inferior coolants on the market contain nitrite, and the coolant is silicate, so most of the coolants on the market cannot be replaced in Japanese cars.

European coolant:

Europe is the region that attaches the most importance to environmental protection in the world, so the coolant used in European cars, except for the organic acid coolant of the dex-cool type, is mostly a composite coolant. Amines, boron, phosphorus, and nitrites are rejected in European car coolants, but lower amounts of silicates are allowed to be contained to protect aluminum alloy engines.

There is no need to replace, you can add some of the original factory after the less, and this can be done in the 4S store.

The coolant is composed of three parts: water, antifreeze and additives, and can be divided into alcohol, glycerin, ethylene glycol and other types of coolant according to the different components of antifreeze. It is not recommended to add water, because the water will freeze when it is cold, which will harm the car.

Hello, according to the normal situation of the problem you reflected, the life of antifreeze is two years and 60,000 kilometers. If your antifreeze is still less than 60,000 kilometers in this two years, it is recommended that you add the same type of antifreeze, and it is not recommended that you add water. Because of the natural water, it is easy to change the anti-corrosion ability of antifreeze and anti-freezing and anti-high temperature ability.

If there is no way to carry out an emergency, it is possible to add water to carry out an emergency. However, after calling the antifreeze, you still need to change the car question in advance. 4S shop professional technician, 10 minutes to solve. 】

At present, the antifreeze used in automobiles is a long-lasting antifreeze, which needs to be replaced once in ten years or = 100,000 kilometers. If the antifreeze is consumed, add water. [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

The coolant is replaced once every 30,000 kilometers, if your car does not leak, the coolant will not be less, I hope my answer can help you, I wish you a happy drive [car questions, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello! The antifreeze is replaced every 2 years or 40,000 km, whichever comes first! Generally, no leakage or boiling water is not needed!

Antifreeze needs to be replaced. According to the requirements of the maintenance manual, antifreeze should be used at all times, not replaced by water, and should be replaced in time in the summer. However, in the actual car, if in the summer, the antifreeze has reached the replacement cycle, you can temporarily not change it, postpone it for a while, and wait for the winter to change it, there will be no problem.

Hello, in order to ensure that the antifreeze can play a better role in antifreeze, anti-corrosion, anti-rust effect! It is recommended that you replace it every two years or 40,000 kilometers!

Hope it helps! Have a nice ride! [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Try to replace it, if the time is short, less is not much, you can add distilled water. If it takes a long time to replace it directly,. It's not interesting to add this thing, it's not high, and it's durable. The addition must also be exactly the same, otherwise it will be counterproductive.

Hello, it is generally possible to fill the same type of good antifreeze, but after 40,000 kilometers, you have to replace it with a new antifreeze [car questions, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

This depends on the situation you use, add less of it, it's almost summer, and the coolant is very important.

If you have less, you will add it, but I personally recommend that you put it off for 5 years or 100,000 kilometers and replace it

Depending on the quality of the coolant added, it is necessary to replace it in 3-5 years.

If the antifreeze is used for a long time, the effectiveness of the antifreeze will be reduced, so it must be replacedIf the effectiveness of engine cooling cannot be guaranteed, then it may lead to a decline in engine performance, cause damage to the engine, and shorten the service life of the engine.

The replacement cycle of antifreeze is generally 2 years or 40,000 kilometers, which is a reference replacement cycle, which should be replaced according to the actual situation of the car, and can be replaced in advance or postponed for a period of time.

Precautions for daily use of engine coolant.

1. When the temperature is lower than 0, the concentration of antifreeze should be checked regularly.

2. For areas that run above 0 all year round, water that has been treated with anti-rust and anti-scale treatment can be used as coolant, and tap water or natural water is prohibited as engine coolant.

3. Open the lid of the water tank, pay attention to observe whether there are impurities in the antifreeze when the water tank has cooled, keep the liquid level of the liquid storage pot between "max" and "min", and tighten the lid of the water tank after the inspection.

The coolant is for engine heat dissipation, with anti-boiling, anti-freezing and anti-corrosion effects, it will fail after a long time, so the coolant should be replaced, generally once every two years.

Change the engine's coolant based on mileage or length of time, as it is difficult to visually determine the extent of its deterioration.

The full name of engine coolant should be engine antifreeze coolant. As the name suggests, it has two major functions: antifreeze and cooling. Replacing the coolant is to extend the quality and life of the engine.

The full name of antifreeze should be called antifreeze coolant, which means coolant with antifreeze function. Antifreeze prevents coolant from freezing and cracking radiators and freezing engine blocks or covers when the coolant freezes when parking in the cold winter. But we want to correct a misconception that antifreeze is not just for winter, it should be used all year round.

The use of antifreeze in the engine has the following protective effects:

1. It plays a role in anti-corrosion protection for the components of the cooling system.

2. Prevent scale and avoid reducing the heat dissipation effect of the radiator.

3. Ensure that the engine can work within the normal temperature range.

Therefore, the antifreeze of the engine must have the characteristics of anti-freezing, anti-boiling, anti-corrosion, waterproof and non-foaming, and is not affected by the season and region. Among them, freezing point and boiling point are the basic indicators of antifreeze. Taxis must be replaced regularly, generally every two years or every 40,000 kilometers driven, and taxis should be replaced more frequently.

The scientific name of antifreeze is "engine coolant", and the correct way to use engine coolant: Clean the engine cooling system with a cleaning agent before adding engine coolant. Note:

Use complex cleaners instead of acid cleaners. Then clean the cooling system with clean water. Fill the cooling system with clean water and check the sealing parts of the cooling system.

Do not mix with different formulations of coolants. Finally, add engine coolant.

Attention should be paid to the engine coolant during use: Do not overfill when adding: Do not fill up when adding vehicles without overflow boxes (about 95% volume); For vehicles with an overflow box, start the engine for a few minutes and then add engine coolant to the specified height.

Note: Always check the level height of the engine coolant and the tightness of the cooling system. When diluting engine coolant concentrates, use deionized or distilled water. Under normal circumstances, the engine coolant should be replaced every 40,000km of the car, or annually.

Engine coolants from different manufacturers and brands cannot be mixed. Do not add water to the engine cooling system, and do not reduce the concentration of engine coolant in summer.

Choose a brand: Try to choose a well-known brand of engine coolant with good quality. Such as Great Wall multi-effect coolant; Select Freezing Point:

Engine coolant should be selected with a freezing point of about 10 degrees Celsius lower than the minimum temperature in the area where the vehicle is operating. It is important to note that the lower the freezing point, the better the coolant; Select Type:

It is recommended to choose a glycol-type product. For engines made of aluminum alloy, organic engine coolant should be selected; For engines with a high reinforcement coefficient, organic or heavy-duty engine coolant should be used. If you are in Qingdao, Shandong, it is recommended that you use Great Wall FD-1 multi-effect antifreeze 4kg 4L- plastic, the minimum use temperature is minus 25, a barrel of 4 liters, and the market retail **43 yuan, which is very economical.

The general model can be replaced once every 2 years or 40,000 kilometers! Some luxury cars, such as Mercedes-Benz, even have an antifreeze replacement interval of 10 years or 200,000 kilometers. It can be seen that in fact, the replacement cycle of antifreeze is very long, and the owner only needs to replace it according to the deadline on the user manual.

In general, the engine cooling system is shipped with antifreeze coolant (-35°C) that can be used in all seasons. Antifreeze inherently contains rust and preservatives, so there is no need to add other cooling system additives.

There are two points to pay attention to in <> antifreeze: first, it cannot be mixed, and the additives of various brands are different, resulting in the performance of antifreeze being reduced; Second, in case of emergency, such as coolant level alarm, do not add mineral water or tap water, but add pure water or distilled water, which can ensure that it can continue to be used for a long time.

For some joint ventures or imported models, the coolant replacement cycle used is very long, as shown in the figure below, some models of Honda require 10 years and 200,000 kilometers to replace, which can basically be the same life as the engine, and the general engine 200,000 kilometers overhaul, can be replaced by the way. Choose a regular brand of antifreeze. If your vehicle is within the warranty period, it is still recommended to use the original manufacturer, if the warranty period is out, then choose the brand, so that the quality is guaranteed.

In addition, it is also necessary to look at the production date of the antifreeze, if it is not used at one time, the next time you use it to see if there is any sediment in it.

If you are not sure what model the original factory adds, you also have to have the most basic judgment standard, that is, the coolant is basically divided into red, green and blue, we must add a similar color when we add, these additives because of its volatility, so it has a certain aging, in addition to the reason of "unpreventable", rust and scale will still have some. For these two reasons, the coolant has a replacement cycle, generally two years or 60,000 kilometers.
