What is the reason for the coolant spraying on the top of the water tank of the Kaiyue car?

The thermostat, the copper cap on the top is damaged, causing the thermostat to not open, causing the engine circulating water channel to be blocked, and the engine water temperature rises, which is sprayed out of the air vent of the water tank. At the beginning, I didn't feel much of a problem, so I went to the repair shop and asked, saying that the cylinder head cushion was damaged, resulting in the cylinder head gas sealing was not strict, and the high-pressure gas leakage in the combustion chamber made the water temperature of the water tank rise and the antifreeze was backsprayed! It freaks the hell out of me!

The car is original! If the cylinder head is disassembled and the seat cushion is replaced, it will have a certain impact on the engine. Later, when I returned to the town, my brother found me a maintenance master, asked, and said that it should not be the cylinder head cushion is broken, if so, after the cold car starts, open the water tank cover will find that there will be gas coming out, and the water temperature is high, and the antifreeze will be quickly sprayed out.

The damage to the top cover of the thermostat is the phenomenon that there is no water flow in the water tank of the cold car, and there are no bubbles coming out. When the air conditioner is turned on, the water temperature will quickly return to around normal values. After the comparison of the failure and the current situation, it was judged that the latter water heater was faulty, the master quickly disassembled the front section of the air filter, and found that on the left side of the exhaust pipe, it was the connection between the water tank return pipe and the engine, and there were two 6mm screws that were disassembled and broken, and the thermostat leaked out.

The goods sent at half past nine in the morning arrived at half past four in the afternoon, and when the installation was completed, it was dark and depressed to death! After changing such a thing, it took a whole day of hard work, and Ann was completely convinced! No more whining, hey!

The second half of the year is not going well! My cautious driving! Do not go out, do not go out, can go there are 11 roads, far away can do the bus to do, can not ride an electric car hehe, after encountering this phenomenon can be used as a reference, things are not absolute, if the spring of the thermostat is damaged, it is not the case, it will lead to unobstructed water circulation and increased water flow, if you run a short distance, there may be no water temperature directly, no warm air in winter.

There is a little water temperature for long distances, there will be a little warm air, you will feel hot air when you put your hand on the air outlet, and you will feel cold air when you turn on the warm air to the maximum for a while!

It could be a leaking water tank! Check it out in this case! If it really leaks! It is recommended that you go for a replacement! Otherwise, it is easy to pull the cylinder! Hope.

1. The design of the cooling system is unreasonable.

2. The radiator is damaged, and the upper and lower water chambers are poorly sealed, resulting in leakage of antifreeze;

3. The leakage of antifreeze is caused by loose fittings of the overflow tank, water pump joint surface and various pipelines of the cooling system, and poor sealing;

4. The damage of the cylinder gasket, the flatness of the joint surface between the cylinder head and the cylinder block, the flatness, warping and the loosening of the fastening bolts of the cylinder head lead to the high temperature and high pressure gas in the cylinder entering the cooling system, resulting in excessive coolant consumption.

5. Check the water pipeline to see if there is leakage, and check each nozzle to see if it is caused by water seepage.

6. Check whether the water tank cover is faulty, and generally the poor water tank cover will also appear when the water temperature is high.

7. Make sure that the liquid in the car water tank is not pure antifreeze, if it is inferior antifreeze, it will also evaporate too quickly.

What is called coolant is particularly large.

Summary. The first reason is relatively easy to solve, as long as the leakage point is found, it can be dealt with, as for the second reason, it may be that the cylinder gasket is damaged and the coolant enters the cylinder for combustion, and over time there will be a shortage of coolant, and the solution is to replace the cylinder gasket; Or the oil radiator is damaged, the coolant enters the oil channel from the water channel, you can open the oil cap to have no milky oil, if there is a damage to the oil radiator, replace it can be solved.

Hello, I am a car maintenance stool jimic master, with rich experience in the maintenance of high-end models, and has now served more than 2,000 customers. I've seen your question, I'm sorting out the answer, it takes a certain amount of time to type, please wait a while, and I'll reply to your question within five minutes

Hello, the vehicle coolant is gone, only the following two reasons are caused by false shooting: one is the external leakage, such as the water tank, water pipe interface, water pump leakage and other locations caused by water leakage, only need to find the leakage point for treatment: the other is that the water is burned inside the engine, or into the engine and mixed with the oil;

The first reason is relatively easy to solve, as long as the leakage point can be found, it can be buried in the tank to deal with, as for the second reason may be that the cylinder gasket is damaged and the coolant enters the cylinder for combustion, and over time there will be a shortage of coolant, and the solution is to replace the cylinder gasket; Or the oil radiator is damaged, the coolant enters the oil channel from the waterway, you can open the oil cap to see if there is milky oil, if there is, the oil radiator is damaged by the letter, and it can be solved by replacement.

In addition, the causes of water entering the engine are cylinder wall cracks, sand holes, water blockages, etc.

Summary. Hello, in this case, take a car, you try the water temperature, see if it is high, if the water temperature is not high, the bank will run normally in the future, if there is no problem, he will not have much of a problem, the cold car cover opens the water it will splash out a little. This is sometimes whose sun is his family, he will also be a little normal, if the cover is good and runs, the water temperature is normal, not high temperature, no leakage, this will be fine.

What happens when the antifreeze slowly comes out after the cold car opens the lid of the water tank?

Hello, happy to answer your questions.

Hello, in this case, take a car, you try the water temperature, see if it is high, if the water temperature is not high, the bank will run normally in the future, if there is no problem, he will not have much of a problem, the cold car cover opens the water it will splash out a little.

This question must be told to you seriously, the coolant of the car.

It is to maintain a normal temperature while driving, generally the normal temperature is at 90 degrees, then 90 degrees is equivalent to about to boil, if you drive it out at this time, the water will be pressured and spray out, if your people are very close, there are 80% of the time it may be scalded by water.

Therefore, do not open the coolant cap just after the hot car stops. There are several reasons for coolant boiling, some problems such as leaking water tank, fan not turning, clogged water channels and other problems cause the water temperature to be too high. The whole process is hand-typed, begging.

Coolant for cars.

The normal temperature is maintained while driving, and the normal temperature is generally at 90 degrees, and if you turn on the coolant at this time, the water will be sprayed under pressure.

1. Other reasons:

1) Water tank leakage.

2) The fan does not rotate.

3) Some problems such as clogged waterways lead to high water temperatures.

2. How to solve:

1) Change the thermostat.

2) Replace the cooling fan.

3) Replace the cooling water pump.

This problem also exists in my car, now it is normal, you better go and change the original auxiliary tank lid.

1. Cause the water temperature of the engine to be too high even"Bring to a boil"There are many reasons, such as damage to the electronic components of the cooling system (thermostat, cooling fan), poor heat dissipation of the radiator, insufficient coolant, etc.

2. Pull over, but don't turn off the engine immediately! Because the coolant temperature is already high and the cooling capacity has reached its limit, if the engine is turned off immediately, the boiling coolant will stop circulating (for most engines, the water pump is driven by the crankshaft).

3. Of course, if it is an electric water pump engine, it will be better), too high temperature can not be cooled, and the engine is also unbearable. If the engine is left idle for a while, the constant circulation of coolant can still reduce the impact of high temperatures on the engine.

4. Check whether the antifreeze is lacking, resulting in high engine water temperature. The circulation of the coolant, whether the circulation is not smooth. Secondly, you can also check that water temperature sensors, water pumps, thermostats, cooling fans, etc., may cause high water temperatures.

If you don't have a strong hands-on ability, you should go to the repair shop for an inspection.

The only way to do this is to replace the water tank. Then check the cooling system.
