What are the steps of the car antifreeze replacement tutorial

The correct replacement method is a three-step process:

1. Inspection. Before completely replacing the antifreeze, it is necessary to do a comprehensive inspection to see if there are traces of leakage in each pipe and whether there are cracks, the key is to check the five-way water pipe, the five-way pipe is named because there are five interfaces connecting various parts, and the antifreeze is distributed to different parts of the car after flowing through the five-way pipe. If there is a leak of antifreeze in this section, the water pipe should be replaced or the connection should be re-fixed according to the situation.

2. Drain water. Remove the old antifreeze and wash the liquid passage with clean water. Add water to the antifreeze refill tank, then pour the water into the tank, let the water continue to flow through the engine cooling system, and then idle the car for 3 5 minutes to let the water circulate.

Start by pouring pink water out of the jug. Continue pouring fresh water until the water is clean. Be careful not to forget to remove the warm air hose and clean the water inside the warm air tank.

3. Replace with a new liquid.

After draining the water for about 1 hour, add new antifreeze through the water pipe of the tank (radiator). This is how to get the antifreeze flowing into the tank quickly. Then add another bucket of antifreeze antifreeze, add antifreeze to the tank almost complete, the car for about 10 minutes, then cool the part of the cooling system to remove air, the liquid level drops, then add antifreeze, add liquid tank with the highest sign "maxt".

When filling with antifreeze, you need to pay attention to:

1. First of all, you should see the antifreeze filling port, and the antifreeze pot lid is marked with a similar thermometer triangle symbol.

2. Different brands and different colors of antifreeze cannot be mixed, and chemical reactions will occur with different ingredients and different formulas, which will affect the performance of antifreeze.

3. Choose high-quality products of the same brand and model as the original antifreeze.

4. The antifreeze has a certain corrosiveness, do not touch ** and other rubber parts, if there is any splashing, it should be rinsed with water in time.

5. Antifreeze can not be replaced with water, nor can it be added with water, the freezing point of water is low, and the water contains a large number of anion and ion, which will form scale and cause blockage after a long time.

6. Don't add too much antifreeze, not too little, generally there is a water level scale on the antifreeze kettle, add it to the highest water level and the lowest water level scale.

7. Add antifreeze must wait until the vehicle is turned off and cooled, in case the cover is opened at high temperature, and the internal pressure will spray out the antifreeze, which has the risk of scalding.

<>First of all, before changing the antifreeze, inspect the car, open the engine compartment cover, check.

If there are any traces of water leakage at the water tank, water pipe, etc.

It should be dealt with in a timely manner; Start the car again, the temperature reaches 85 90 seven o'clock, the thermostat is turned on, and the cold Wu Qiaoxi system enters a large cycle, which helps to discharge the cylinder block.

antifreeze inside the water jacket; Turn off the ignition and allow the engine to cool down, and then open the reservoir lid or water tank lid to help the antifreeze drain quickly.

Swift and thorough; Then, confirm the way the vehicle water tank drains, the model is different, and the water.

The way the box drains is also different. There is a direct opening of the tank drain valve.

The drain valve is sufficient, and if there is none, the water inlet pipe under the water tank can be removed.

row emissions. If the discharge is not complete, the cooling system can be cooled with a water pressure gauge.

The system is pressurized internally, so that the antifreeze drains more completely, and passes through the water.

The pressure of the pressure gauge can check whether there is a slight unknown leakage in the system, and the leakage point in the cavity is easy to find;

Second, after draining the antifreeze, close the drain valve.

Or connect the water pipe under the water tank, and then add it to the water tank and the liquid storage tank.

into clean water; Then start the car, idle for 3 5 min, let the new addition.

The water that goes in is fully circulated, and the scale and old antifreeze inside the system are cleaned.

liquid, drained again; Finally, make sure that there is no antifreeze in the water that comes out Rinse it well, drain the water, close the drain valve, or fill it with water.

The water pipe under the tank is filled with new antifreeze; When filled, idle the operation.

For about 10 min, let the antifreeze fully circulate and exhaust the system, at this time, the liquid level will drop, and the antifreeze will be replenished again to the specified level.

up to the level of liquid.

In addition, antifreeze, like any other product, has an expiration date. During use, if there are suspended solids, sediments, or deterioration, discoloration, or pH value less than 7, it should be exhausted.

Quickly change the antifreeze and clean the wide elimination system. Under normal circumstances, it needs to be replaced every 2 3 years or about 40,000 km, but the specific situation.

The situation still depends on the actual situation of the vehicle. When replacing antifreeze, drain the water from the cooling system, preferably with a radiator cleaner to remove limescale and sediment. For models that do not have an automatic exhaust function, it is also necessary to change the antifreeze.

Exhaust the system to prevent air blockage.

The specific operation process: first check the dust god carefully check the situation of the car, then open the front hood, open the engine compartment cover, check the specific situation of the car under a blind cover, to see if there is any water leakage, if everything is good, start the car, when the temperature reaches a certain level, turn on the thermostat, wait for a period of time and then turn off, and then after the engine cools, open the liquid reservoir cover, and replace the antifreeze Paizun liquid.

The operation process of the specific defense file is to directly open the front chassis cover of the car, then find the device of the antifreeze carrying the messy liquid, unscrew the bottle mouth of the antifreeze, then remove the antifreeze, pour out the antifreeze inside, and then pour the new antifreeze into it, Chachun screws the bottle mouth and puts it back in its original position.

First release the antifreeze, then clean the engine cooling system in the morning, then add the antifreeze to the water tank, cover the water tank lid, start the engine, idle and open for three minutes.

The correct way to replace the antifreeze for the car is as follows:

1. Inspection, before completely replacing the antifreeze, we must first do a comprehensive inspection to see if there are traces of leakage in each pipe, whether there are cracks, the key is to check the five water pipes, the five pipes are named because there are five interfaces connecting various parts, and the antifreeze is distributed to different parts of the source car after flowing through the five pipes. If there is a leak of antifreeze in this section, the water pipe should be replaced or the connection should be re-fixed according to the situation.

2. Drain the water, release the old antifreeze, and then clean the liquid channel with clean water. Clean water is added to the antifreeze refill tank, which is then filled with clean water to continuously flow through the engine cooling system, and then idling for 3 to 5 minutes to circulate the water. 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.

Note: Don't forget to remove the warm air water pipe and drain the water in the warm air tank;

3. Change 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".

Millions of car purchase subsidies.

1. Start the hot car: loosen the screws of the drain port under the water tank, heat up the car for about 5-10 minutes, at this time the thermostat should be in or is in the open state, the water circulation in the engine begins, the thermostat valve is opened, and the old antifreeze is naturally flowed out with atmospheric pressure first.

2. Cleaning: Pour in the cleaning agent of the water tank, then pour in the water mixture, continue to start the car, let the water temperature rise, until the temperature saving valve is opened, the electronic fan rotates, and the mold cleaning agent is released, which is cleaner.

3. Re-cleaning: Same as above, clean again with water, then release water, blow with air, and blow all the residual liquid.

4. Add liquid: Add new antifreeze, continue to start the engine until the electronic fan rotates, and add the liquid level to the standard line.

5. Rehydration the next day: Before starting the car the next day, check whether there is any deficiency of anti-orange Xiang freeze when the car is cold, and add it to the standard line by yourself when it is missing. Each of the above mentioned that the car should be started until the temperature saving valve is opened, this is because the temperature saving valve is not opened, and there is still residual antifreeze that cannot be released.
