Why is the structure of the car water tank different, so what is the importance of adding coolant?

Because each brand has a different idea when designing a vehicle, there are differences. Try to follow your car's instructions and don't add too much.

There are two forms of car radiators, one is open and the other is closed. The coolant in the open water tank should be added to the normal scale first, but the water tank is easy to lose the coolant, so it should be refilled. The closed water tank with coolant does not need to be refilled.

You can add water in the auxiliary water tank, the main water tank is more dangerous to open when the car is hot, you only need to add water in the auxiliary water tank, once the main water tank is short of water, you can suck it into the main water tank from the auxiliary water tank. If you don't feel at ease, you can also add water to the main water tank when the car is cool.

There are two types of automobile water tank structures: open and closed. After 10 years, it is basically closed, and it is best to use the same model and specification to supplement the coolant, and warn everyone not to change the anhydrous coolant due to flammability, overheating, and fast consumption.

It can cause the engine to overheat. Overheating of the engine will cause certain damage to the engine.

If the temperature of the car engine is too high, the owner can carry out some checks:

1. The fan motor does not move or the fan clutch is faulty, and it cannot be cooled down normally.

2. The three-way catalytic converter is blocked or the tube is ruptured, resulting in the exhaust being blocked, resulting in overheating of the engine.

3. The pipe of the cooling system is ruptured, resulting in the loss of coolant and the heat dissipation cannot operate normally.

4. After the long-term use of the water pump is highly worn, the parts are worn out and fall off.

5. If the pressure of the cover of the radiator is different, the spring will be loosened and the cover cannot be closed tightly.

6. The thermostat cannot be switched on and off normally, which is usually caused by mechanical failure or incomplete filling of the cooling system. It may also be that the newer thermostat has a different temperature coefficient than the original.

The car water tank should be filled with antifreeze. The water in life is impure and contains impurities, if the water circulates in the engine, especially when the large circulation flows into the cooling box behind the air intake grille, the impure water will produce scale to block the cooling system, which will lead to the aggravation of the engine weakness and wear, and the high-temperature water is easy to evaporate, resulting in a lack of water in the cooling system, which will cause the cylinder to be pulled and the cylinder head to be deformed, and more seriously the engine will be scrapped.

In principle, coolant must be added, but the coolant is mixed with antifreeze and water according to the use of the manufacturer, and in fact, the coolant can be used under the condition of non-freezing to meet the minimum temperature. If you use it in Hainan, you don't need to add antifreeze, just add water. However, in Heilongjiang in Northeast China, you have to add antifreeze with less water, or even add anhydrous antifreeze.

The role of antifreeze:

1. 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, anti-boiling in summer, waterproof scale and anti-corrosion throughout the year.

2. The engine and its cooling system are made of metal, including copper, iron, aluminum, steel and solder. These metals come into contact with water at high temperatures, and over time, they will be corroded and rusted. Antifreeze not only does not corrode the engine cooling system, but also has anti-corrosion and rust removal functions.

3. At present, more than 95% of domestic and foreign water-based antifreeze uses ethylene glycol, compared with tap water, the most significant feature of ethylene glycol is antifreeze, and water can not 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.

The car water tank must be filled with antifreeze, and must not be filled with water.

The tap water we usually use in our daily life can be used to cool the engine, but the water in life contains impurities, if the tap water circulates in the engine, it will produce scale to block the cooling system after a long time, and after the cooling system does not work properly, the engine will accelerate wear, and the engine will accelerate weakly, the tap water is easy to evaporate at high temperatures, and after a period of time, it will lead to a lack of water in the cooling system, which may cause the engine to pull the cylinder or the cylinder head to deform.

The car water tank needs to be filled with antifreeze, but not directly. The water tank is the radiator of the car, which has cooling kinetic energy, and the water can indeed be used to cool the engine, but adding water directly to the water tank will damage the vehicle and cause harm to the car.

The car water tank is, of course, filled with water.

Only in the cold winter will the car water tank be added with refrigerant liquid, and at other times it will be added with ordinary water.

The reason is to prevent the car from operating normally after the car water tank freezes in the cold winter; Other times of the year it's economic.

Why? I invite you to talk about it, and if anyone has anyone who says about it? If there is someone who talks about it, I ask you to talk about me about it, okay?

I thank you for giving me a little bit of this question.

When adding coolant to the car, the difference between the main water tank and the auxiliary water tank is: different filling amounts, different filling methods, and different deflation methods.

First, the amount of filling is different.

1. Main water tank: It needs to be filled up when adding water.

2. Auxiliary water tank: When adding water, it needs to be added to the upper engraved line.

Second, the way of raising is different.

1. Main water tank: Flame out and fill cooling water.

2. Auxiliary water tank: start the vehicle and continue to add cooling water when filling to the lower engraved line.

3. Different deflation methods.

1. Main water tank: There are special exhaust screws.

2. Auxiliary water tank: automatic exhaust at the circulation pipe of the water tank.

Water tank, no. The main water tank and the auxiliary water tank are connected, and the antifreeze is mainly in the main DAO water tank.

The boiling point of the antifreeze inner liquid is higher than that of water, up to about 125 degrees, lower than the freezing point of water, up to about minus 30 degrees, and the antifreeze rarely produces scale, and has an anti-rust formula, which is very beneficial to the engine, under normal circumstances, the impact of adding water will not be too great, it is recommended to add coolant as much as possible, and the antifreeze is added to the water tank of the car.

When adding BAI coolant to the car, in the main water tank.

The difference between DU and auxiliary tank addition is that the amount of DAO filled, the filling method is different, and the release gas method is different.

First, the amount of raising weight is different.

1. Main water tank: It needs to be filled up when adding water.

2. Auxiliary water tank: When adding water, it needs to be added to the upper engraved line.

Second, the way of raising is different.

1. Main water tank: Flame out and fill cooling water.

2. Auxiliary water tank: start the vehicle and continue to add cooling water when filling to the lower engraved line.

3. Different deflation methods.

1. Main water tank: There are special exhaust screws.

2. Auxiliary water tank: automatic exhaust at the circulation pipe of the water tank.

First fill up the main water tank and close the water tank lid tightly. Then add the upper scribe line to the secondary tank. The auxiliary water tank belongs to the expansion water tank, the coolant flows into the auxiliary water tank after being heated and expanded, and the coolant will flow back to the main water tank after cooling.

1. What is automotive refrigerant?

It is actually antifreeze, which is a chemical synthetic preparation, as long as the purpose is to prevent the cooling system of the engine from freezing at low temperatures, and secondarily to dissipate heat.

Second, the role of automobile antifreeze:

1. Anti-freezing. Coolants formulated with glycol can be used at temperatures as low as -70. The concentration of ethylene glycol in the coolant sold on the market is generally maintained between 33 and 50, that is, the freezing point is between -20 and -45, which is often reasonably selected according to the actual needs of different regions to meet the requirements of use.

2. Anti-boiling. Ethylene glycol added to water changes the boiling point of the coolant. The higher the glycol concentration, the higher the boiling point of the coolant, which is reached at -20 and at -50.

3. Anti-corrosion. The main function of coolant is to protect against corrosion. The use of deionized water and appropriate additives can prevent the occurrence of various types of corrosion.

4. Anti-rust. Rust is caused by oxidation within the cooling system. Additives in the coolant help prevent the appearance of rust in the cooling system channels.

5. Anti-scale. The deionized water used in the coolant protects the engine by avoiding the formation of fouling and sediment. The refrigerant has the effect of lubricating and cooling the seal and reducing the noise of the compressor.

3. The method of adding car coolant: add new antifreeze by the water pipe of the water tank (radiator), then add another bucket of antifreeze to the antifreeze tank, add until the antifreeze tank is almost full, and drive for about 10 minutes. The amount of antifreeze added is between max and min of the reticle, and the cap is screwed on.

Generally, the amount of antifreeze replacement is about 5-6L, and the amount of a barrel of antifreeze on the market is about 4L.

The main and auxiliary tanks are connected, and the antifreeze is mainly in the main tank. When the car is hot, the antifreeze expands, leaving the excess in the auxiliary water tank, and when it cools, the secondary water returns to the main water!

The car only has two water tanks, a wiper water tank and a cooling water tank, of course, the coolant is added to the cooling water tank, please see the logo on the lid of the water tank.

If only a small amount of antifreeze can be added from the auxiliary tank, if there is no antifreeze in it, it needs to be added from the main tank. I asked the maintenance staff at 4S point, and the answer was that it would be very slow to add a large amount of antifreeze from the sub-tank, because the water pipe of the sub-tank is very thin, and a small amount of replenishment can be added by the sub-tank, and you can judge whether it is full according to the scale.

There is no difference, and even some models can only be added from the auxiliary tank, if the main tank has a stopper, then remember it in that house, it will be faster.

The filling speed is different, and the auxiliary tank has a scale.

Water tank, no. The main and auxiliary tanks are connected, and the antifreeze is mainly in the main tank.

The boiling point of antifreeze is higher than that of water, up to about 125 degrees, lower than the freezing point of water, up to about minus 30 degrees, and antifreeze rarely produces scale, and has an anti-rust formula, which is very beneficial to the engine, under normal circumstances, adding water will not have too much impact, it is recommended to add coolant as much as possible, antifreeze is added to the water tank of the car.

It depends on where your car is driving all year round, if it is in the area north of the Huai River, you need to add coolant, coolant is also called antifreeze, you can not release water at sub-zero temperatures, to prevent freezing and cracking the engine;

If you are in the south of the Yangtze River for a long time, you can add water, you don't have to use coolant, there is no car anti-freezing problem, but in the area where the temperature is high, the coolant will evaporate, it is not very convenient to replenish, and it is much more convenient to add water.

First, although the car's water tank has a water word, it really doesn't add water to it. Water should not be used at any time, unless it can be replaced by water in the event of a malfunction, because most of our current engines are aluminum alloy cylinder heads and blocks.

Second, the role of the water tank is a heat dissipation system, antifreeze in addition to anti-freezing at the same time also has anti-corrosion, anti-rust, anti-boiling, anti-scale bucket elimination effect, if the use of water will also cause scaling and blockage to the radiator, reduce heat dissipation efficiency, lead to high engine temperature and other problems, cast iron engine water is also easy to rust.

Third, it is easy to use water at high temperature in summer, because the boiling point of water is 100 degrees, and the boiling point of antifreeze is generally about 110 degrees, so it is more important to use antifreeze in summer.

Fourth, in addition, the coolant has a certain lubricating effect on the seals of the water pump, which can prolong the life of the water pump, but if the area is hot, then you can consider adding water, mainly for convenience.

Abstract: Of course, the car water tank is coolant!

First, the freezing point of water is 0 degrees and the boiling point is 100 degrees. At present, antifreeze can achieve a freezing point of minus 45 degrees Celsius and a boiling point of more than 110 degrees. So coolant is also called antifreeze.

So if your winter temperature is below 0 degrees, add water to your car and don't drive if it freezes!

Second, in the coolant, the base fluid is water + ethylene glycol. Then a lot of additives are added. The additives are mainly anti-rust, and prevent limescale and keep the cooling system clean.

And water has no anti-rust effect. The water flow at high temperature constantly impacts the water pump, which is also prone to "cavitation cavitation" and accelerates the aging of the water pump.

Is the car water tank added to the water, or coolant? Why?

The car water tank is, of course, coolant-added! First, the freezing point of water is 0 degrees and the boiling point is 100 degrees. At present, antifreeze can achieve a freezing point of minus 45 degrees Celsius and a boiling point of more than 110 degrees.

So coolant is also called antifreeze. So if your winter temperature is below 0 degrees, add water to your car and don't drive if it freezes! Second, in the coolant, the base fluid is water + ethylene glycol.

I'm talking about being in the South.

In **, you need to add the solution.

The car water tank needs to be filled with antifreeze, but not directly. The water tank is the radiator of the car, with cooling kinetic energy, and the water can indeed be used to cool the engine.

The method of adding antifreeze to the car envy boiling water tank is as follows:

1. Turn the pressure cover in a counterclockwise direction, if you hear a hissing sound, wait until the sound disappears before opening it;

2. Fill an appropriate amount of coolant into the coolant expansion tank to reach the position between the max and min scales of the expansion tank;

3. Start the engine when the coolant expansion tank cover is opened;

4. After starting the engine, the coolant in the tank will be slowly reduced, and then add an appropriate amount of coolant to the expansion tank until the liquid level reaches the position between max and min degrees of the coolant expansion tank;

5. Reattach the lid and make sure the pressure cap is tightened by hand and fully seated.
