Is it normal to have small bubbles in a car water tank kettle

Car water tank. Is it normal for bubbles to appear, so let's find out together.

Abnormal. The normal condition of the cooling system is that there are no bubbles, and the formation of air bubbles will cause antifreeze.

The ability to absorb the heat of the engine becomes poor, which affects the water temperature and is easy to rise, and there are bubbles in the antifreeze in the water tank, which may be damaged by the cylinder gasket and needs to be repaired and replaced.

Car Radiator Maintenance Project:

1. Avoid "boiling" the car. The car water tank is most afraid of boiling, that is, the temperature is too high, and you should look at the temperature displayed on the dashboard when driving. If you notice that the temperature is too high, you must stop the car for detection.

2. The smoke from the car water tank should be stopped decisively for detection. Once you notice that the engine is smoking, open the front engine cover of the car immediately after parking the car to increase the heat dissipation speed. It is best to choose a ventilated place to park in a tunnel or a relatively closed place as much as possible.

3. Change the coolant regularly. If the coolant in the car water tank circulates for a long time, it is inevitable that all kinds of magazines will occur, which will affect the effect of heat dissipation, so it should be replaced regularly according to the time on the vehicle instructions.

Tap water cannot be used to replace coolant. Special care should be taken not to add tap water instead of coolant, due to the chlorine contained in tap water.

The components will cause corrosion and rust to the water tank, engine and other systems, make the cooling system not cool smoothly, and cause the engine temperature to be too high.

Abnormal. The normal situation of the cooling system is that there are no bubbles, and the generation of bubbles will make the coolant's ability to absorb engine heat worse, resulting in the water temperature rising easily, and the bubbles in the coolant of the water tank may be damaged by the cylinder gasket and need to be repaired and replaced.

Is it normal to have small bubbles in a car's water tank? This is normal.

In the operation of the car, the water from the water tank cover upwards and bubbling is mainly due to the poor sealing of the combustion chamber and the high temperature combustion gas of the diesel engine entering the cooling water cavity, so to solve the problem of water bubbling in the water tank, the sealing problem of the combustion chamber should be solved first, and the following phenomena are the main reasons for the sealing failure of the tender burning chamber:

1. The cylinder head is warped and deformed, and the bottom plane of the cylinder head is uneven.

2. The top plane of the cylinder block is uneven.

3. The torque of the cylinder head fastening bolt is not enough, and the fastening bolt is not evenly tightened according to the symmetrical cross several times.

4. The residual slag in the bottom hole of the cylinder head bolt on the top plane of the cylinder block makes the torque of the cylinder head bolt insufficient, and the phenomenon of "false tightness" occurs.

5. The threaded hole and threaded tapping of the cylinder head bolt on the cylinder block are not in place (the effective length of the threaded hole is not enough).

The water from the water tank cover upwards and bubbling is mainly due to the poor sealing of the combustion chamber and the high temperature combustion gas of the engine entering the cooling water cavity, so to solve the problem of water turning and bubbling in the water tank, the sealing problem of the combustion chamber should be solved first, and the following phenomena are the main reasons for the sealing failure of the tender burning chamber.

When the water temperature of the engine is high:The water pump pumps the water repeatedly to reduce the temperature of the engine, (the water tank is composed of hollow copper pipes.) The high-temperature water enters the water tank through air cooling and circulates to the engine cylinder wall) to achieve the purpose of protecting the engine, if the water temperature is too low in winter, the water circulation will be stopped at this time to avoid the engine temperature is too low.

The automobile water tank is mainly composed of radiator core, water pipe, heat dissipation air blades, upper water tank and lower water tank. The upper water tank is on the radiator, and the upper water tank is connected to the water tank under the radiator by the water pipe.

It should be that the cylinder gasket is flushed, and it is easy to cause high temperature, and the water pipe feels very hard and stressful. When there is a problem of erosion of the cylinder gasket, the power of the engine will be reduced, resulting in insufficient cylinder pressure, and even in severe cases, the carburetor will return fire, the exhaust pipe will be discharged, etc.

Burning engine head gaskets and compression leaks are common failures. After the cylinder gasket is burned, the working condition of the engine will be seriously deteriorated, so that it cannot work, and it may also cause damage to some related parts or parts; In the compression and power stroke of the engine, it is necessary to ensure that the upper space of the piston is well sealed and there is no air leakage.

Car water tank precautions.

The tank should not be overfilled. If you add too much water or even fill it up at the same time, it will cause a large amount of water to overflow due to "thermal expansion", leaving a lot of water traces and scale on the surface.

At the same time, adding water will also produce scale in the cooling system, clogging pipes, affecting heat dissipation, and damaging the engine. In addition, the most suitable working temperature range for general automobile engine operation is 75-90, and high or low is not conducive to the work of the engine.

The bubbles in the water tank are generally caused by the high-pressure gas in the cylinder channeling into the cooling water channel. The causes of blow-in and how to eliminate them are as follows. 1. The cylinder head nut is not tightened according to the specified torque.

If the torque is too small and the cylinder head is not compressed, the high-pressure gas will escape into the waterway. The cylinder head nut should be tightened according to the prescribed torque and re-tightened periodically. 2. The cylinder gasket has been used for too long, and it has been washed out or burned, and the sealing has deteriorated, resulting in air leakage.

To replace the cylinder head gasket with a new one. 3. The plane of the cylinder head is uneven or deformed, resulting in air leakage. The cylinder head plane should be ground or the cylinder head should be replaced.

4. Improper assembly, resulting in fracture and blow-in at the shoulder of the cylinder liner table. Replace the cylinder liner with a new cylinder liner in accordance with the prescribed method. 5. The height of the shoulder of the cylinder liner is not enough or the depth of the shoulder hole on the body is too large, resulting in the cylinder sleeve being inserted into the body, the plane height of the protruding body is not enough, or even sagging, and the gas will flow into the waterway from the shoulder.

Therefore, it should be tested before assembly, check the amount of protrusion, and ensure that it is within the allowable range.

Hello empty dust, 1: When changing the cylinder gasket, the cylinder block and cylinder head are not clean.

2: There are cracks in the cylinder head (when there is a shortage of water at high temperature and lack of water, it is easiest to add water to the cylinder head without waiting for the engine to cool down), generally between the gas gates If it is gas in the water, it will be gone after a day at most.

The easiest way to check: when the car is cold, open the water tank cover, start the engine, and then use your nose to smell whether there is a smell of oil smoke at the mouth of the water tank.

The main reason for the bubbling of the car water tank is because the pressure inside the water tank is too large, the pressure inside the water tank is too large, it may be because the water pipe is blocked, of course, it refers to the ventilation pipe of the water tank, the water pipe is blocked, the cylinder gasket is burned, and the cylinder gasket is damaged, the pressure of the rigid force may enter the cooling system, in addition, check the sealing of your water tank cover, if the water tank cover is not well sealed, it will also cause the water tank to bubble.

If you find that the car water tank is bubbling, then it must be a leak in the water tank, check the ** where there is dripping, if there is none, it is basically the cylinder head gasket is broken.

The bubbling in the water tank is caused by water leakage in the cooling system or before boiling and air in the cooling system, which should be eliminated and repaired in time.

The reasons for the bubbling of the automobile water tank are as follows: 1. Poor sealing of the car: during the operation of the car, the water from the water tank cover is turned upwards and the bubbling is mainly due to the poor sealing of the combustion chamber and the high-temperature combustion gas of the diesel engine entering the cooling water cavity, so to solve the problem of water turning and bubbling in the water tank, the sealing problem of the combustion chamber should be solved first.

2. The water temperature of the water tank is too high: the water boiling of the car usually refers to the situation that the working temperature of the engine of the car reaches a temperature that is too high for the normal working temperature range, which affects the normal operation of the machine and damages the machine. The so-called excessive temperature refers to more than 85 degrees, and some can even reach 100 degrees.

If it's a car in poor condition, you may even see the water tank steam coming out like a less open teapot.

Check the cooling system for blockages and water leaks. Check that the belt is in compliance with the regulations. When adding water before leaving the car, refuel the engine at idle speed to see if the water in the water tank is turned up.

Indicates that the radiator is partially blocked. If the engine has a "sudden" sound, the cylinder gasket must be rushed and needs to be replaced. It's easy to turn on the air conditioner, and check the air conditioning system.

What causes a bubbling water tank? If the car water tank is bubbling, then your water tank is boiling, you have to stop the car immediately, turn off the engine, and then find a repairman, or tow the car to the repair shop to repair, if you continue to drive, then your engine will be burned out by the boiler.

Check the water tank, is there any leakage? If it is repaired, if the water tank is not leaking, check the connection between the water tank and the engine, if it is not, it may be that there is a problem with the engine, otherwise it is a lack of refrigerant, if it is to make up for it, so as to ensure the safe operation of the engine.

What kind of car is Ponyville? There may be something else. It is said that Sun Wen is too big in Thailand.

Summary. If the water temperature is high and the antifreeze does not leak, it will decrease by itself, and the water tank will bubble when the lid is opened.

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

There is also a lack of water. Hello, the car water tank is bubbling. This may be talking about the air dismantling the water temperature sensor and patting the engine to observe the air.

This maintenance is about 3-50 **, if the air is still so respectful, it is to consider that the cylinder gasket is broken, resulting in bubbling, this is troublesome, you need to disassemble and assemble the pure cylinder head to the cylinder gasket, in order to solve the problem.

The head gasket is broken, what are the symptoms?

If the water temperature is high and the antifreeze does not leak, it will decrease by itself, and the water tank will bubble when the lid is opened.

The last question is how much does it cost to repair a broken head gasket.

It depends on what kind of car you are. Then you can know the approximate**.

Jinbei Zhishang S30

For the 4A13 engine, disassemble and assemble the cylinder head, replace the cylinder head gasket, and get it together is about 1000.
