Can antifreeze change color? Will the discoloration of the antifreeze affect the use?

The color of the antifreeze cannot be changed because the original antifreeze has a fixed color, and changing the color may cause the antifreeze to not function.

Types of antifreeze:

1. Ethylene glycol antifreeze.

Ethylene glycol is a colorless, slightly viscous liquid, the boiling point is, the freezing point is, and can be mixed with water in any proportion. After mixing, the freezing point is significantly reduced due to the change in the vapor pressure of the cooling water. The degree of its decrease decreases with the increase of ethylene glycol content within a certain range.

2. Diethylene glycol antifreeze.

Diethylene glycol - water antifreeze, not easy to volatilize and ignite, and less corrosive to metals, but the effect of diethylene glycol in reducing the freezing point is lower than that of ethylene glycol, and when preparing antifreeze with the same freezing point, the dosage is larger than that of ethylene glycol, and the heat conduction efficiency decreases. In order to reduce costs, many manufacturers will mix ethylene glycol and diethylene glycol.

2011-12-20 09:36 For the problem of replacing antifreeze in vehicles, in principle, it is recommended to replace the special antifreeze specified by the original factory, mainly because its performance in all aspects will be more suitable for the cooling system of the original car compared to other brands, but if you are ready to replace other brands of antifreeze, there will be no problem, but the operation will be relatively cumbersome, Because two different brands and colors of antifreeze are easy to produce adverse reactions due to the different ingredients, resulting in a decrease in the antifreeze effect, and even the possibility of generating flocculent to cause the blockage of the cooling system, and in serious cases, it will also cause abnormal corrosion to the engine water jacket and cooling pipeline, so it is necessary to thoroughly clean the antifreeze of the original car before replacement, and it is necessary to rinse it thoroughly with clean water several times, mainly to prevent the antifreeze residue of the original car, and then you can add other brands of antifreeze to use. Therefore, as long as the above operation method is used to replace, there will definitely be no problem. Who:

The pink color of the antifreeze may be caused by the deterioration of the antifreeze, which is divided into two situations, one is that the antifreeze has reached the service life and needs to be replaced, so it will deteriorate and discolor; Another situation is that when the antifreeze is replaced, the water tank is not cleaned, and the old antifreeze remains in it, and when the new antifreeze is added, the two will react, so the discoloration will occur.

If you find that the antifreeze turns brown, it will affect you somewhat, and it is best to replace it with a new antifreeze to better protect the engine.

The antifreeze needs to be replaced regularly, and the general service life is about 2 years or 40,000 kilometers, and as a commercial vehicle (taxi), the antifreeze can be replaced once a year, which can better protect the engine and provide a good working environment for the operation of the engine.

Hope it helps!

The discoloration of the antifreeze does not affect the normal use, as long as the antifreeze of the car is still within the validity period, then it is normal for the discoloration to occur.

Summary. Dear, hello, I'm glad to answer for you this car antifreeze as long as the color is the same, this can be added, pro, this antifreeze, it generally has two colors, one is red, one is green, as long as the color of this antifreeze is the same, you can add, if the color is not the same, this can not be added, like this Volkswagen Tiguan, he is all red antifreeze, you only need to add this red antifreeze can the same antifreeze can be added pro, Take a look at the above answers, I hope it can help you, I wish you a happy life, all the best, and everything goes well<>

Can you add <> antifreeze as long as the color is the same?

Volkswagen Tiguan 2016

Dear, hello, I'm glad to answer for you this car antifreeze as long as the color is the same, this can be added, pro, this let the cavity collapse antifreeze, it generally has two colors, one is red, one is green, as long as the color of this antifreeze is the same you can add, if the color is not the same, this can not be added, like this Volkswagen Tiguan, he is red antifreeze, you only need to add this red antifreeze can add the same antifreeze pro, Yuanpai take a look at the above questions and answer them frankly, I hope to help you, I wish you a happy life, all the best, and everything <>goes well

<> adding a little antifreeze of the same color will damage the car.

Dear, hello, this Volkswagen, it is all using this red antifreeze.

This antifreeze of the same color is added to this, and this is not damaged to a car, dear.

Just add this antifreeze of the same color, dear.

He's all red antifreeze, just add the red one, dear.

If you add this red antifreeze, it won't have any effect on the engine system.

What if it's a different color.

If you have different colors, this can easily lead to the phenomenon of high temperature of the engine.

This causes damage to the engine cooling system and pulls the cylinder at high temperatures.

If it's red, add red, and if it's green, add green.

Only add a little bit to different colors.

If you only add a little bit of different colors, this won't be enough, and you can't add more.

If you add a little bit of different colors, this is fine, but you can't add more, you can't be half red and half green.

In the case of this general antifreeze, this is the same color plus the same color.

If you add it, you will generally not be wrong, as long as you add this red and red, you can do it.

Is it time to change the color of the antifreeze? Is it time to change the color of the antifreeze? The color of the antifreeze has changed and it is necessary to change it more sideways:

1. If the antifreeze changes color, it is likely to be because of the deterioration of the antifreeze, which not only does not have a good antifreeze effect, but also has a reduced cooling effect on the engine. Then when the engine is running at high temperature, due to the lack of good cooling effect, the viscosity of the oil will also be reduced, and the parts of the engine will be worn out over time, and it is even possible to scrap it directly; 2. After some antifreeze is stored for one year, there will be a small amount of flocculent precipitation, which is mostly caused by the precipitation of additives and combustion, and does not need to be thrown away. If a large amount of particles precipitate, it means that the antifreeze has deteriorated and can no longer be used; 3. For those vehicles that run for a long time, such as taxis, etc.

Generally, high-quality antifreeze is replaced every year, while those with short operating hours can be replaced every two years or every 30,000 km. @2019

<> "Why antifreeze is divided into different colors.

<> "Why antifreeze is divided into different colors.

There is often a lot of fluid on the car to provide auxiliary effects for various parts of the car, and these fluids are not permanent, but need to be replaced every once in a while, including antifreeze.

This knowledge is generally known to car owners, but simply for the antifreeze thing, many people have some doubts, such as: why is the antifreeze still divided into different colors? Car mechanic: I don't understand this, do you want to wait for the car to burst the cylinder?

When it comes to antifreeze for automobiles, its role is still very large, and its main role is to ensure that the oil is not frozen under low temperature conditions.

However, it would be a mistake to think that antifreeze is all about this, because antifreeze also prevents aging and rust of individual parts, and can also equalize the temperature of individual parts even at high temperatures. That's where antifreeze really comes in.

If there is a lack of antifreeze, especially in the cold winter, the parts or fluids of the car may be frozen, causing the vehicle to fail to start and operate normally.

And when it comes to antifreeze, how many colors can it be divided into? There is some truth to this.

Because antifreeze is not the same as ordinary liquids. In order to avoid the occurrence of accidental ingestion, the antifreeze is designed to be distinguished by different colors. In addition, the different colors of the antifreeze also mean that the composition of the antifreeze is not the same.

As a simple example, if the antifreeze contains glycerin, then the antifreeze will be red, and if the antifreeze contains ethylene glycol, the antifreeze will appear green, and if the antifreeze contains propylene glycol, then the antifreeze will appear blue. By using these colors, it is possible to determine the special ingredients contained in the antifreeze.

Finally, it is important to note that it is precisely because of the different colors of these antifreezes that the ingredients contained in them can be judged to vary greatly.

So when it comes to changing antifreeze, we need to look clearly. What kind of antifreeze is the original, when you replace it, you also need to replace the antifreeze of the same composition, and you can't mix it. Otherwise, there is a high chance of a cylinder burst.

Now you know why antifreeze can be divided into different colors, right?
