Can different colors and brands of antifreeze be mixed together?

Of course, it is not allowed to be mixed together, because the composition of each brand of antifreeze is different, and if it is mixed together, it is not good for the car, and it accelerates the consumption of the car, so it is best not to mix together.

I think it's better not to, because it's likely to cause some irreversible consequences, and the gains outweigh the losses.

It is not allowed to be mixed together. Because this will have some impact.

No. Antifreeze with different ingredients or colors must not be mixed, because if you mix antifreeze with different ingredients, the antifreeze will react chemically and cause the antifreeze to fail.

If the antifreeze is the same and the color is different, it cannot be mixed, and the chemical composition of the additives is different for different colors or different brands of antifreeze, and if it is mixed, a chemical reaction is likely to occur between a variety of additives, resulting in the failure of the additives.

Generally, they can be mixed and used without any problems.

The whole process of antifreeze is called "antifreeze coolant", its main function is actually to circulate between the engine and the radiator to dissipate heat for the engine, the body is actually "water", "antifreeze" is mainly to keep it in a liquid state when the temperature is below freezing in winter and maintain the function, will not cause the water tank to rupture due to freezing, etc., only to add certain substances (such as ethylene glycol) to it to make its freezing point drop, and then it will not freeze in winter.

Therefore, different antifreezes can be mixed, and even in special cases, it is acceptable to fill the tank directly with water (in order to prevent limescale, it is better to use softened water).

However, from the perspective of car maintenance, it is also necessary to replace the antifreeze in time to ensure that it works normally when the temperature is low.

Antifreeze is a kind of coolant containing special additives, mainly used in liquid-cooled engine cooling system, antifreeze has excellent properties such as antifreeze in winter, boiling in summer, waterproof scale and anti-corrosion throughout the year. At present, more than 95% of domestic and foreign water-based antifreeze uses ethylene glycol, and compared with tap water, the most significant feature of ethylene glycol is antifreeze, while water cannot be antifreeze. Secondly, ethylene glycol has a high boiling point, low volatility, moderate viscosity and small change with temperature, and good thermal stability.

Therefore, glycol-based antifreeze is an ideal coolant. Many drivers are generally accustomed to using antifreeze in winter and switching to tap water in summer, thinking that this is more economical and cost-effective, but in fact, it is not. Preventing freezing, preventing the cylinder and radiator from freezing and cracking are only the most basic functions of antifreeze, and antifreeze also has other important functions, such as anti-boiling, anti-scale, anti-corrosion, etc.

The use of antifreeze in summer can effectively prevent the water tank from "boiling", and the use of antifreeze throughout the year can prevent scale formation in the water cooling system and inhibit the corrosion of various metals. Usually drivers ignore the harm of "scale", in fact, the harm of scale to the car is quite large, the thermal conductivity of scale is very small, is 1 25 of cast iron, 1 50 of brass. With scale, the thermal conductivity of the coolant is greatly reduced, the engine temperature rises, and the corrosion is aggravated, which promotes the increase of scale, forming a vicious circle, and the scale may also block the pipeline of the cooling system, causing greater accidents, according to the relevant domestic data reports, in the maintenance work of the normal use of the automobile engine, 6% is the engine cooling system failure, and the main reason for the failure is the scale and metal parts are corroded, which shows how harmful the scale and metal parts corrosion is to the engine water cooling systemTherefore, the use of high-quality antifreeze all year round can not only effectively protect the car's water cooling system, but also effectively save money.

The requirements for engine antifreeze include: high boiling point, low freezing point, excellent ability to resist rust and corrosion, prevent the formation of deposits such as scale, prevent foam formation, etc.

Due to the different components and proportions of various types of antifreeze, the freezing point is also different, so it should be selected according to the local temperature conditions. Generally, the freezing point of antifreeze should be lower than the local minimum temperature of 10 15; When preventing boiling in summer, the antifreeze should reach at least 108 or more, so as to avoid the failure of the antifreeze when boiling.

There are many colors of antifreeze on the market today. For example, Great Wall Multi-Effect Antifreeze is fluorescent green, Caltex Premium Antifreeze is orange, Blue Star Antifreeze is blue, and Tongli Antifreeze is red. The antifreeze itself is a colorless and transparent liquid, and the reason why these antifreeze are made into bright colors is mainly to make it easier to distinguish and distinguish some dyes, and another function is to prevent accidental ingestion.

The color of antifreeze is not necessarily related to performance and quality. The Great Wall multi-effect antifreeze is prepared in a special fluorescent green color, mainly to facilitate leak detection.

There are many types 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), glycerol (C3H5 (OH)3, commonly known as glycerin), lubricating oil and common sugar, honey in our daily life, etc., can be used as the mother liquor of antifreeze. Unpolluted rainwater, snow water, etc., can become antifreeze in the general sense when the total hardness component concentration of the water quality is between 0 and 30 ppm.

At present, most car manufacturers around the world use ethanol, ethylene glycol or glycerol as the mother liquor of automobile antifreeze, especially ethylene glycol antifreeze. At present, the vast majority of imported and domestically produced automobiles in China use ethylene glycol antifreeze.

On the label of antifreeze, the main ingredients are generally marked, although the colors are different, but if the main ingredients are the same, the mixing will not have much effect. Sometimes, even though the color is the same, the main ingredients are different, so you must not mix them. However, it is not recommended to mix different brands of antifreeze with the same ingredient, and if it is for emergency purposes, it is not impossible to add a little.

OK. Because the composition of antifreeze of the same color is almost identical, it can be mixed.

It is possible to mix them, but they are not recommended. Different brands of antifreeze, even if they are the same color, may have different ingredient formulations, but the same dye is used. The risk of mixing with antifreeze of the same color is smaller, but it does not mean that it is completely safe.

As the industry evolves and formulations change, the composition of antifreeze varies greatly, which greatly increases the risk of mix-up.

I don't think so, because different colors of antifreeze have different additives, and mixing them may cause damage to the water tank.

Different colors of antifreeze should not be mixed. After the red antifreeze is mixed with the green antifreeze, because the main components of the two are different, there may be a chemical reaction, resulting in precipitation or bubbles in the water tank where the antifreeze is stored, causing loss to the cooling system and rubber seals, and in serious cases, impurities will be generated to block the cooling system pipes. After the cooling system pipe is blocked, the antifreeze will not be able to exert its effect normally, and the engine will not be able to dissipate heat in time, and wear will occur.

Antifreeze usage tipsAntifreeze is not just about antifreeze, but it is about raising the boiling point. Generally speaking, the freezing point is -35 and the boiling point is 108, because the temperature of the engine is around 97 when it is working. If the temperature is a little higher, this is not a problem.

Because the temperature is not completely constant for the car, it will fluctuate.

If you use water, the boiling point of the water is 100, and if it is a little higher, it may boil and bubbles will be formed. As soon as the bubble appears, the water pipe inside will be blocked, which may directly lead to problems with the entire heat dissipation system. So whether it's winter or summer, it's necessary to use antifreeze.

Antifreeze of the same color and brand cannot be mixed. There are many types of coolant in the auto parts market, "coolant" is actually just "antifreeze", most of them are made of alcohol and water mixed with pigments, there is no additives that coolant should have, its boiling point is about 90, corrosive, easy to lead to lead to overheating of the engine and the occurrence of blind envy.

Coolant, the full name should be called antifreeze coolant, which means coolant with antifreeze function, antifreeze can prevent the coolant from freezing and cracking the radiator and freezing the engine cylinder block when parking in the cold season, but to correct a misunderstanding, antifreeze is not only used in winter, it should be used all year round, the normal maintenance project of the car, every year of driving, the engine antifreeze needs to be replaced.
