How to change the antifreeze. How do I change my antifreeze?

With autumn and winter in the middle of now, it's the season to change the seasons and maintain your car, and replacing the antifreeze is a top priority. So, how do you change your antifreeze?

1. 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 harms to this:

One is to reduce the freezing point of antifreeze, which will freeze the body in severe cold weather; Second, it is easy to cause the water tank to scale and rust, blocking the cold cycle.

2. Pay attention to whether the replaced antifreeze is a fake or shoddy product. Antifreeze generally has a color, the darker the color, the stronger the antifreeze ability, some black-hearted stores in order to make profits, on the inferior antifreeze to add some pigments, it seems to be concentrated, but after adding to the water tank, due to its cold resistance is not enough, resulting in the large circulation of the cooling system and the thermostat will freeze. This inferior antifreeze must be thoroughly drained from the tank and replaced with a high-quality antifreeze.

3. Don't prepare your own antifreeze. In order to save money, some riders prepare antifreeze without special measuring cups, thermometers, hydrometers and other measuring tools. If the concentration (specific gravity) of the preparation is too low, its cold resistance is not enough, and it is easy to freeze the water tank and engine; If the concentration (specific gravity) is too high, it will cause the heat dissipation effect of the water tank to be poor, and the engine will overheat.

4. Do not mix two different brands of antifreeze at the same time. Because the technical standards of antifreeze prepared by different manufacturers are different, if they are mixed together, they will produce chemical reactions in the tank and lose their antifreeze effect.

5. Do not change the antifreeze frequently. In general, the antifreeze should be replaced every two years, and frequent replacement will cause unnecessary waste.

6. 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 replacement, it is recommended that you go to the franchise stores of Beijing Chinap Auto Care and Beauty Service Headquarters in all parts of the country, use a no-dismantling cleaning machine to thoroughly clean the cooling system, and then add high-quality antifreeze, and if necessary, add a bottle of cooling lubricant, so that the maintenance effect will be better.

Unscrew the lid and pour it on both sides underneath the front cover.

I believe that the expensive materials and man-hours of 4S stores have discouraged many car owners, and they have forced themselves to become a DIY master with strong hands-on ability. The main topic of this article: Do you know the steps to replace antifreeze?

Antifreeze replacement**.

1. Unscrew the lid of the water tank, open the water tank discharge valve, generally at the bottom of the car, and release the antifreeze.

2. Clean the cooling system and continuously inject clean water into the engine cooling system. During the flushing process, the engine should be idled to maintain the circulation of clean water inside until the water tank is released.

3. Stop filling the water, wait for the water to run out, and close the water valve.

4. Fill a new antifreeze until the liquid level is between the max and min water level scales.

5. Cover the lid, start the car, and make the engine idle for two or three minutes, the cooling system will discharge the air inside, and the antifreeze liquid level will be reduced, and the antifreeze should be replenished again.

What are the consequences of adding too much antifreeze?

Adding more antifreeze to the regular brand will not have any effect, adding more antifreeze in the process of car use, will be subject to thermal expansion, overflow from the pressure relief valve, there is no harm, but it will leave some stains, but it is best to use a syringe to pump out the antifreeze beyond the highest water level.

Antifreeze has a shelf life, which is generally about 2 years, and high-quality and long-lasting ones have 5 years. Once the antifreeze exceeds the expiration date, the engine waterway is easy to cause rust, which will cause blockage, cause high temperature of the engine and even open the pot.

Note: On the other hand, the antifreeze produced by some inferior manufacturers is corrosive, which will not only cause damage to the cooling system, but also cause damage to the wires and other equipment in the engine compartment due to the overflow of antifreeze, and in serious cases, it will directly ablate the water tank and flow into the engine.

1. Drain water. One thing to note here is that if the car has just finished driving, be sure to wait for the vehicle to cool down before starting to replace it. Because the engine at this time is at a high temperature, it is very easy to burn.

The common and formal method of draining water is to unscrew the drain screw at the bottom to allow the antifreeze to flow out of the hole in the screw. To use this method, you need to use a jack to lift the car first, which will be slower. Another way is to unplug the water pipe directly, so that the operation of the water discharge is fast and does not require a jack to top the car.

2. Use a basin to connect the antifreeze to the bottom of the car, start the car at the same time, let the engine move, and idle for 2 3 minutes. This is to allow the antifreeze to flow thoroughly and to leave as little residue as possible.

3. Clean the cooling system. Insert the rubber tube into the water tank filling port, fill it with water through the rubber pipe for cleaning, turn on the warm air, and let the clean water circulate throughout the cooling system until the water flowing out becomes colorless clear water, and then you can add antifreeze.

4. Turn off the fire, close the water drain screws in the water tank, and add new antifreeze from the filling port. Unscrew the reservoir cap, add antifreeze, and reach the MAX scale.

5. Start the engine, at this time, the cooling system will expel part of the air through operation, the antifreeze level will be lowered, and the antifreeze will continue to be replenished to the "MAX" scale line.

6. Cover the filling port cover and engine cover.

Hello dear, I am glad to serve you, I hope my answer can satisfy you. The method of replacing the antifreeze is as follows: first drive the vehicle into the working area of the lift and open the lid of the coolant expansion kettle (to ensure that the engine is cold). 2.

Lift the vehicle to the appropriate working height and drain the antifreeze by unscrewing the plastic drain screws on the engine cooling tank (some models may require the bumper to be removed to unscrew the drain screws). 3.After the antifreeze is drained, put down the vehicle and pressurize the mouth of the expansion kettle with high-pressure gas to discharge the residual antifreeze inside the engine.

After draining, screw the drain screw on the water tank. 4.Pour the new antifreeze into the expansion kettle, start the vehicle after it is full, the antifreeze level will drop significantly, and you can replenish the antifreeze in time.

When the engine water temperature rises and the antifreeze level stabilizes at the normal level, the engine is turned off. 5.Lift the vehicle again and check the drain screws for leaks.

If there is no leakage, replace the antifreeze.

Antifreeze prevents coolant from freezing and cracking radiators and freezing engine blocks when parking in the cold winter.

1. The service life of antifreeze is 2 years or 40,000 kilometers.

2. During the shelf life, the liquid level height needs to be checked every six months to make up to the normal range.

3. Replace the antifreeze thoroughly before expiration.

4. Note that different brands and models of antifreeze should not be mixed.

Hello, the replacement steps are as follows:

Pull the handbrake, jack the car up with a jack, put the basin under the antifreeze, open the antifreeze pot, follow the antifreeze pot to find the water pipe clip or water outlet, unscrew the water nozzle, put the antifreeze outlet, and then screw the clip, and fill the antifreeze jug.

1. Inspection: The bottom pipe is named because there are five interfaces connecting various parts, and the walking process of antifreeze must flow through the bottom pipe and then distribute it to different parts of the car to play a role. Therefore, before completely replacing the antifreeze, it is necessary to do a comprehensive inspection to see if there are cracks and leakage traces in each pipe, and if there is a leakage of antifreeze, it is necessary to replace the water pipe or re-fix the interface according to the situation.

2. Drain water: Before replacing the new antifreeze, it is best to clean the liquid channel with clean water and release the old antifreeze. The specific operation method is to add clean water to the antifreeze replenishment tank, and then inject clean water into the tank to make the water flow continuously through the engine cooling system, and then idle for 3 to 5 minutes to let the water 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.

3. Replace the new liquid: After about 1 hour of draining the water, add the new antifreeze through the water pipe of the water tank (radiator), which is the method to let the antifreeze flow into the water tank quickly. Then add another bucket of antifreeze to the antifreeze tank, add it until the antifreeze tank is almost full, and drive for about 10 minutes, at this time, the cooling system has removed part of the air, the liquid level has dropped, and then add the antifreeze to it, and fill the highest mark of the storage tank "maxt".

After draining the water for about 1 hour, a new antifreeze is added through the water pipe of the tank (radiator), which is a method to allow the antifreeze to flow into the tank quickly. Then add another bucket of antifreeze to the antifreeze tank, add it until the antifreeze tank is almost full, and drive for about 10 minutes, at this time, the cooling system has removed part of the air, the liquid level has dropped, and then add the antifreeze to it, and fill the highest mark of the storage tank "maxt".

The shelf life of car antifreeze is generally two years, so it is necessary to replace the antifreeze every two years, or the car travels more than 30,000 kilometers.

Be careful when adding antifreeze.

The color of the original antifreeze, the color of the added antifreeze should be consistent with the original color, otherwise the freezing point is easily affected, do not add water to the water tank instead of antifreeze, otherwise the cooling point of the antifreeze will be increased and it is easy to freeze.

The first is not to mix antifreeze between different brands and models, and the second is to switch to different brands of antifreeze coolant, drain the original antifreeze, and re-add the newly purchased antifreeze.

Under normal circumstances, the car needs to be replaced with antifreeze after 3000 to 4000 km. Here's how:

1) Drain water: Unscrew the water tank cover, open the water tank drain valve, and release the antifreeze.

2) Cleaning: Insert the rubber pipe connected to the tap water pipe into the water tank filling port, open the tap water, and make the tap water flow through the engine cooling system continuously. During the flushing operation, the engine should be idled and the above operation should be maintained until the water tank is discharged.

Turn off the tap and allow the cooling system to drain the water before closing the tank drain valve.

3) Liquid addition: Add antifreeze from the water tank filling port to fill the water tank. Unscrew the lid of the reservoir, add antifreeze, and reach the "MAX" scale, taking care not to exceed the "MAX" scale. Close the tank lid and reservoir lid and tighten tightly.

4) Exhaust rehydration: Start the engine, idle for 2 3 min, and unscrew the water tank cover. At this time, the cooling system will lower the level of antifreeze due to the removal of part of the air, and the antifreeze should be replenished again until the antifreeze reaches the "max" scale mark.

5) Cover the water tank cover: open the water tank cover, pay attention to the state that the water tank has cooled, pay attention to observe whether there are impurities in the antifreeze, the final liquid level should be kept between "max" and "min", and the water tank cover should be tightened after the end.

After draining the antifreeze, install the drain plug or warm air pipe, then add clean water to the water tank and add new antifreeze.

When adding antifreeze, do not spill water on the engine, when adding antifreeze, if the antifreeze is sprinkled on the spark plug hole seat of the engine, the high-voltage wire jack, and the distributor, it may have an impact on the flashover, and the water splashing on the transmission belt may also cause it to slip, and spilling on the body may also cause the body to deform and even crack.

Choose the appropriate freezing point antifreeze according to the area where the vehicle is located, and it is generally recommended to use antifreeze 10-15 degrees lower than the low temperature where it is located. Do not touch the antifreeze, the antifreeze and its additives are toxic substances, do not touch, and put in a safe place, the coolant released should not be used again, and the waste coolant should be disposed of in strict accordance with the relevant regulations.

Replacement process

Antifreeze can also prevent the coolant from boiling prematurely, improve the boiling point of the antifreeze, and prevent the water tank from "boiling" prematurely. The air in the antifreeze is agitated by the impeller of the water pump and produces a lot of foam, which will prevent the heat dissipation of the water jacket wall. Foam inhibitors are effective in inhibiting foam production.

Different types of antifreeze should not be mixed, otherwise it is easy to cause chemical reactions, generate precipitation or bubbles, reduce the use effect, when replacing the coolant, the cooling system should be rinsed with clean water, and then add new antifreeze and water, and the name of the remaining antifreeze should be indicated on the container to avoid confusion.

Yes, but it is technically difficult to change the antifreeze by yourself and need to exhaust it. If you are a newbie, you can learn more about the forum and close the post first.

The steps to change antifreeze in a car are as follows:

1. Open the car cover, before completely replacing the antifreeze, you should do a comprehensive inspection to see if there are traces of leakage in each pipe and whether there are cracks.

2. Clean the liquid channel with clean water: add the water to the antifreeze replenishment tank, and then inject clean water into the tank to make the water flow continuously through the engine cooling system, and then idle for 3 to 5 minutes to let the water circulate.

3. Add the new antifreeze through the water pipe of the water tank (radiator), and then cover the water tank cover and the liquid reservoir cover and tighten it.

Precautions for the use of antifreeze:

The antifreeze must be replaced every two years, because the validity period of the antifreeze is two years, and the expired antifreeze will cause corrosion of the cylinder block, and even cause serious damage to the engine. In addition, the freezing point of antifreeze is generally around -25, and if you go to a colder place, you need to change to an antifreeze with a lower freezing point. Smile.

Traditional inorganic antifreeze should not be mixed with water, which will generate precipitation and seriously affect the normal function of antifreeze. Organic antifreeze can be mixed with water, but not too much water.
