What is the reason why the coolant in the tank boils and spews out after parking

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. If the engine temperature is too high, the coolant will overflow from the refill tank cover due to excessive pressure after boiling, and the cause of the high engine temperature should be found for treatment. 2. The water temperature is too high, because it is cooled by natural wind and fans during driving, and the fan stops working after stopping and turning off. 3. There is also the possibility that the water tank and water pipe are blocked, and the water tank cover and the water tank cover connected to the engine are leaking.

The function of the water tank is to dissipate heat from the working engine, prevent mechanical overheating, metal expansion, affect the work, the water of the water tank is a special car antifreeze, which can prevent icing and water temperature is too high, higher than the boiling point of water, generally not leaking, no need to add water, 40,000 kilometers is recommended to replace, according to the surrounding environment and vehicle use, you need to check the water level regularly, many do not need to add.

Extended information: Precautions for adding water to the car water tank: 1. Cool down and reduce pressure before adding water, when the water storage of the water tank is insufficient, stop immediately, let the engine idle and run at idle speed, use the fan to dissipate heat, and never turn off the fire to prevent the cylinder from sticking to prevent the hot gas from spraying out when opening the water tank cover.

2. When the hot car opens the lid of the water tank, it should be carefully scalded, stand on the side of the air outlet on the water tank, wrap the water tank cover with a damp cloth, and turn the head and body to one side, and slowly open it. 3. No matter what season it is best to use refrigerant liquid, water will produce rust, which is not conducive to heat dissipation. 4. The cooling water to be filled should be clean and soft water, so as to avoid the formation of scale in the cooling system and block the waterway.

Hello, happy to answer your questions.

Hello, in this case, the pressure of the water tank is too high and the water tank cover cannot be sealed, or there is a flush gasket to flush the cylinder. There is also the fact that the fan dissipates heat abnormally, and the water temperature is too high. Like this case, we can first check whether the water tank cover is normal to replace the water tank cover, if it still doesn't work, we go to check whether its cooling fan is dissipating heat normally, check whether the temperature of the upper and lower water pipes of his water circulation is consistent, whether the water pump is working normally, if it is not good, it is to use the computer to detect the fault and repair it according to the fault.

Antifreeze is an important consumable in the cooling system, the car cooling system is an indispensable component of the car, it can keep the engine stable output power, many car friends have encountered the situation of antifreeze overflowing from the kettle, the reasons are as follows:

1. Check whether the lid of the pot is damaged, the temperature in the pot is high, if the lid is broken, the antifreeze will flow out.

2. Add more antifreeze, if the antifreeze exceeds the engraved line on the kettle, the car will cause overflow during driving, and the overflow will not occur if the antifreeze is not much.

3. Thermostat failure, thermostat failure will cause the water temperature to be too high, the coolant will not be able to enter the engine waterway for large circulation, and the antifreeze will overflow if it circulates in the water tank for a small cycle.

In addition, the overflow of water from the auxiliary water bottle after the car is turned off is also a common thing, and the automobile auxiliary water tank is also an important part of the cooling system, and its main role is to play a role in balancing the pressure of the water tank.

When the engine temperature is high, the liquid swells, and a part of the antifreeze will flow into the auxiliary tank through the lid of the tank, and when the temperature drops, the pressure of the cooling system will suck the antifreeze from the auxiliary kettle back into the tank. The auxiliary kettle has a corresponding engraved line, and if you add too much antifreeze, it will cause the auxiliary kettle to overflow. At the same time, you can also see whether the current amount of antifreeze is sufficient.

The water temperature is high, check whether the water tank fan is working properly, the temperature signal of the water temperature sensor, and the pressure of the kettle lid.

Summary. Hello, this phenomenon belongs to the high water temperature, first of all, the water tank cover is not tightly sealed, and then there is the thermostat is not opened, and the water tank fan is not dissipated, and finally the cylinder gasket is flushed.

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

Hello, this phenomenon belongs to the high water temperature, first of all, the water tank cover is not tightly sealed, and then there is the thermostat is not opened, and the water tank fan is not dissipated, and finally the cylinder gasket is flushed.

The water temperature is 90 degrees Celsius.

It depends on how many degrees the decoder is, if the water temperature is not high and the water is not flushed, it is caused by the poor sealing of the water tank cover.

Water comes out of the small hole in the jug of the auxiliary tank.

The mechanic helped me change the water pump, and it shouldn't be the reason for the water pump.

Replace the water tank lid with one.

Forget about the pump change.

Sub-tank cover.

That's right, the lid is not tightly sealed.

I can only try、The kettle is also new、It seems that there is no such situation when I changed it。

Yes, let's try it instead.

Is it possible to flush the head gasket.

The lid was dealt with first, the water temperature of this thing is not high, and the cylinder head gasket basically does not like to break.

If I can help you, please give me a thumbs up Thank you!

Summary. Well, a lot of heat is generated during the operation of the vehicle. During normal use, the temperature will be lowered by the fan of the water tank.

But the normal working temperature of the engine is around 100 degrees. That is to say, even if the water tank dissipates heat, it will control the temperature at about 100 degrees. If he stops, he will be at 100 degrees.

If there is no fan to cool down, it will take a long time for the temperature to drop from 100 degrees Celsius. So it's very hot to touch that water pipe after you park it, it may be very hot. For less than 20 minutes, the temperature in the engine compartment will not drop below 80 degrees.

Hello, happy to answer your questions.

Well, the vehicle generates a lot of heat during operation. During normal use, the temperature will be lowered by the fan of the water tank. But the normal working temperature of the engine is around 100 degrees.

That is to say, even if the water tank dissipates heat, it will control the temperature at about 100 degrees. If he stops, he will be 100 degrees next to the bureau. If there is no fan to dissipate heat, it will take a long time for this temperature to come down from 100 degrees Celsius.

So it's very hot to touch that water pipe after you park it, it may be very hot. For less than 20 minutes, the temperature in the engine compartment will not drop below 80 degrees.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can be consulted at any time to ask the car to ask the question, 24 hours ** answer.

When driving, the fan rotates and the water temperature is normal, the water pump does not care about the brigade after the ignition is turned off, the cooling water is no longer circulated, the fan stops working at this time the engine temperature is too high, the water in the cylinder will boil, and come out from the small water tank, the water temperature is too high, and sometimes it will spray out. The reasons for the high water temperature of the engine are: radiator fouling, poor water flow in the cold acre, loose pump belt, low pump speed, poor closure of the water tank cover, failure to form a fully enclosed cooling system, and so on.

Summary. Hello, high water temperature:

1.Check whether the temperature of the upper and lower water pipes is the same, check whether the fan is rotating, check whether the antifreeze is enough, check whether there is any water leakage, and check the sealing of the water tank cover. Check that the thermostat is not stuck. Check whether the impeller of the water pump is off and the cylinder gasket is broken.

2. Maintenance cost, thermostat 150, antifreeze 120, fan 350, water tank cover 60, water pump 260, cylinder head head 1000

What happens when the water tank is spewed out after the car is stopped and turned off?

Hello, don't worry, I can ask for your question, but wait a minute, I need text for about 2 minutes.

Hello, high water temperature: 1Check whether the temperature of the upper and lower water pipes is the same, check whether the fan is rotating, check whether the antifreeze is enough, check whether there is any water leakage, and check the sealing of the water tank cover.
