Can antifreeze of the same color be mixed?

Different types of antifreeze should not be mixed. The main reason is that the role of antifreeze is antifreeze, anti-corrosion, anti-rust, it is made of various chemical additives, and the formula of antifreeze of different manufacturers is very different. At present, the colors of antifreeze on the market are divided into red, green and blue, if it is a small amount of supplement, you can use the same color of antifreeze, and different colors of antifreeze can not be mixed.

The chemical composition of the antifreeze is different, and there may be a chemical reaction after mixing, which will destroy the original essence of the antifreeze, and in severe cases, it will also lead to tank corrosion, blockage, leakage and pump failure.

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.

If the color is the same, the main ingredients are almost the same, and they can be mixed. (Especially for antifreeze of the same brand and quality, the formula is basically the same and can be mixed); The main ingredients of the same color are very different, and it is absolutely not allowed to mix them in this case. Otherwise, a chemical reaction will occur.

There are three main colors of antifreeze on the market today. The main components of antifreeze are ethylene glycol, propylene glycol, and diethylene glycol. Ethylene glycol is usually green, propylene glycol is red with orange, and diethylene glycol is blue.

The antifreeze itself is a colorless and transparent liquid, and the reason why these antifreezes are made in bright colors is because some dyes are added to make it easy to distinguish and identify. If different colors of antifreeze are mixed together, such as ethylene glycol and propylene glycol, they will react at high temperature and pressure to form a gelatinous base.

Although the main components of domestic antifreeze are the same, the additives of different manufacturers are different, so various pigments are added to distinguish them. There are light green, green, light blue, dark blue, pink, orange, red, and many more. If mixed, it is difficult to say that different additives do not produce chemical reactions, which is not good for the tank.

Hello question. Answer: Hello friend, according to your situation, if you mix antifreeze of the same color, it is okay if the color is different, and if you add one piece of antifreeze, it is not okay.

I don't ask a lot of questions.

Question: I was driving on the road, and suddenly the fault code lit up.

So I found a car repair shop, and he added it for me.

They also know that it's okay to answer this, anyway, if it's the same color, add a little bit of this, and we'll all be like this if it's okay, because as long as it's the same color of antifreeze, this has no effect.

Ask a question, okay, thank you.
