How to deal with the car boiling, how to deal with the car boiling

Stop the engine and let it idle, then flush the water tank with water to cool it down, open the tank lid and fill with coolant.

Hello, please go to a professional repair shop for inspection and repair.

First of all, a comprehensive inspection of the car's cooling system is the primary way to prevent boiling. Check whether the fan is normal, whether the water tank is leaking, whether there is a lack of coolant, if the water tank is leaking, it needs to be repaired or replaced in time, if the water tank is short of fluid, it needs to be replenished in time, and if the coolant is turbid and deteriorated, it needs to be replaced. Secondly, do not use tap water as the engine cooling medium, in summer, the engine operating temperature rises greatly under the scorching sun, and the boiling point of water is only 100, which can not meet the heat dissipation needs of the engine at all.

In addition, switch to anhydrous coolant, which contains no water and has a boiling point of up to 191 to quickly remove excess heat from the engine. Usually the owner should also pay more attention to the change of the water temperature gauge in the dashboard, if the water temperature gauge pointer is too high, the car should be driven to a large car repair shop as soon as possible for inspection.

Hello in the boiling pot, goodbye in the boiling pan.

Stop, turn off the ignition, open the canopy.

The whole water tank is like a boiling teapot going straight out of steam, because the weather temperature is not high, hit ** ask me why do I boil? In fact, there are many reasons for the car to boil, in addition to the hot weather, the overload of the air conditioner, the failure of the heat dissipation element and the lack of water in the water tank will make the car boil.

When we encounter an alarm of high water temperature, we should first slow down, and then drive the car to the side of the road, do not rush to turn off the engine, because the water temperature is too high, which will cause the temperature of the piston, steel wall, cylinder, crankshaft, etc. to be too high, and the oil will become thinner and lose its lubrication. If the engine is turned off at this time, the parts are in a state of expansion, and the gap between the accessories is very small, which causes some soft metals to fall off after the shutdown, and some even cause the cylinder to stick. Therefore, do not turn off the heat immediately after you find that the pot is boiling, but keep idling for the time being to try to cool down.

Do not pour cold water on the engine when cooling down, as this may cause the engine block to burst due to the sudden cooling. The correct way is: put on gloves, add a multi-folded wet cloth to the water tank cover, gently unscrew the water tank cover with a small regret seam, wait for the water vapor to slowly discharge, and after the water tank pressure drops, add cold water or antifreeze.

Due to the seepage of water pipes and the lack of cooling water, distilled water or purified water can be supplemented for emergency use, and maintenance can be carried out when it is convenient. Just be careful not to open the lid of the water tank when heating the car to avoid being burned by the water vapor sprayed by the strong pressure inside. If there is enough water, look at the fan behind the tank, which should be running even after the ignition is off when the water temperature is high.

If the fan does not move, turn the fan blades first to see if the fan motor is stuck, and you can easily turn it under normal conditions. If there is no problem with the motor, check the fan fuse, which is one of the reasons for many occurrences, especially in the summer when the electricity consumption is high. Thermostat failure is also the cause of high water temperature, once the failure will cut off the cooling water circulation, when the water tank above and below the two thick glue pipes have obvious temperature difference, that is, the thermostat is damaged and faulty, need to be removed and replaced, which is generally handed over to professionals to deal with.

If the water temperature is a little high when driving, you should pay attention to whether there is too much mud, cotton wool or gravel on the surface of the water tank, which will cause the heat dissipation capacity of the water tank to decrease, and it is best to clean it up when washing the car. For older models, the high water temperature may be caused by limescale deposition in the water tank and inside the engine, so you need to go to a professional store to clean it.

There are many reasons for the car to boil, in addition to the hot weather, the overload of the air conditioner, the failure of the heat dissipation element and the lack of water in the water tank will make the car boil. I have compiled the relevant content, welcome to enjoy and learn from it.

What is the reason for the car tank to boil.

1. Long-term water circulation will cause the slow loss of water, resulting in a lack of water in the water tank.

2. If there is dirt in the water tank, such as mud, rainwater, etc., it is easy to rust the water tank.

3. When the temperature is too high, you can use your hand to touch the temperature of the upper water pipe and the lower pipe to judge, if the temperature difference between the two water pipes is large, it can be judged that the thermostat size cycle conversion is not working properly.

4. If there is air in the cooling system, it will form air resistance, which will make the cooling water circulate poorly, resulting in high engine temperature.

5. If the vehicle is driving on a dirt road or muddy road for a long time, there will be some dirt adhering to the radiator, which will affect the heat dissipation effect over time and cause the water temperature to be too high.

Precautions for opening the car water megabox.

In summer, it is easy to open the water tank, which means that the refrigerant in the water tank has reached the boiling point, and the boiling is very harmful, and the car hurts people, so it has also attracted widespread attention.

Driving on the hot asphalt road, suddenly glanced at the water temperature gauge near the dashboard, and found that the temperature had reached 100 degrees Celsius. Maintenance experts warn that this move is too reckless. If you have been adding antifreeze, 100 degrees Celsius refers to the source is still within the normal temperature range and has not reached the boiling point, the temperature of the antifreeze is between 85 degrees Celsius and 105 degrees Celsius is considered normal, and its boiling point is 120 degrees Celsius.

If you add water, it is estimated that the pot is about to open, but do not tease and care whether it is antifreeze or water, at this time you can not open the lid of the water tank, because there is water vapor in the tank at this time, the pressure is very high, once the lid is opened, the water vapor will be sprayed out, and the consequences are very serious.

Summer is a season that annoys people who have a car and socks, because in the hot summer, the car may suddenly "open the pot", burst or spontaneous combustion, among them, the most common problem encountered by the owner is "open the pot", for this problem, the old driver may have found the trick, the new driver may be experiencing, the following is for the novice to solve the problem of "boiling" the car.

What happens when the pot is boiled.

In fact, the so-called "boiling pot" means that the water in the car's water tank reaches the boiling point. The performance of "boiling the pot" is obvious, clumps of steam will come out under the car cover, and when you open the case cover, you will find that the water in the tank has boiled and even splashed outward. It was as if the car was going to be completely paralyzed, and it was not surprising that the old boss had more opportunities, and the novice would definitely be scared when he met it for the first time.

The biggest connection with "boiling" is the poor work of the engine cooling system, such as the water pump is damaged or the water supply is insufficient, the engine is short of water due to water leakage, the thermostat is not opened, the cooling fan does not rotate or the speed is not enough, the air in the waterway is not exhausted, the water tank is too dirty and the heat dissipation is poor, and the engine knocks.

What to do when you encounter "boiling the pot".

What if the car really "boils"? Don't panic, you can DIY yourself. The steps are simple:

Park the vehicle in a cool place, let the car idle and run, check whether the radiator fan is running normally, turn on the power machine cover to improve the heat dissipation rate, wait for the water temperature to drop, turn off the heat, check whether the coolant level is normal, if it is missing, slowly add the fiber supplement to fill the appropriate coolant.

In this way, the problem of "boiling the pot" is solved.

How to avoid "boiling the pot".

We not only encounter problems and solve problems, but also should prevent them early, how to prevent the car from "boiling"? First of all, check the cooling system frequently, especially to check whether the thermostat is working properly. Check whether the water tank is short of water before leaving the car every day, if there is a shortage of water, it should be filled up in time, and you can also put a bucket of water in the trunk in case of emergency.

When driving for a long distance or for a long time, you should always pay attention to the indication reading of the water temperature gauge, the normal temperature is between 85 and 95, if the water temperature is too high, it is best to stop and rest, and you can turn off the air conditioner when you are stuck in traffic. Secondly, clean the surface of the water tank frequently, because dust and the like adhere to the surface of the water tank, which will seriously affect the heat dissipation of the water tank. And do not use water with high mineral content for a long time, such as mineral water, river water, etc., as a coolant.

This kind of water can easily fill the heat dissipation system with limescale, which will affect the heat dissipation.

The first step is to find a safe place to pull over, let the vehicle idle and do not turn off, because the cooling fan and cooling after the ignition is turned off.

The fluid cycle will stop, which will make the engine hotter;

The second step is to open the hood, increase air circulation, so that the water temperature drops, and then add water to the radiator and cover it, unscrew the first gear, etc.

The internal water vapor is discharged and then opened;

The third step is not to add coolant immediately, the water will be boiled in a closed container will produce a certain pressure, if the water is boiled immediately after the fight.

Open the radiator water port, the internal pressure will make the boiling water spray out, which is likely to cause scalding;

Fourth, check whether there is any leakage in the water tank connection pipeline, and then check whether the coolant is sufficient, if there is no available coolant on the car, you can replace it with mineral water first, but replace it with a new coolant afterwards;

Fifth, in the face of engine overheating, what ordinary people can usually do is to check and add coolant, as for others like water pumps, temperature saving.

If it is caused by a malfunction, it is better to ask for rescue.

<> under the scorching summer sun, driving for too long, and then encountering traffic jams from time to time, if you are not careful, the car "heat stroke" will occur. There are many reasons why your engine can overheat, and when this happens, try to check the following recommendations:

1.Thermostat Blockage: Thermostats that do not switch on and off properly are usually caused by mechanical failure or incomplete filling of the cooling system. The temperature coefficient of the newer thermostat is different from the original one, which is the cause of failure.

2.Fan problem: The fan motor does not move or the fan clutch is faulty, and it cannot be cooled normally.

3.Coolant leakage: If the pipe of the cooling system is ruptured, the coolant will be lost and the heat dissipation will not operate normally; This situation can be improved by simply changing the new pipe.

4.Radiator cover: If the lid pressure of the radiator is not the same, it will cause the spring to loosen and the lid will not close tightly.

5.Exhaust: The three-way catalytic converter is blocked or the tube is ruptured, causing the exhaust to be blocked, causing the engine to overheat.

6.Water pump: After the long-term use of the water pump is highly worn, the parts are worn out and fall off; The only solution is to replace the pump with a new one.

Fault phenomenon: The water temperature gauge needle quickly points to the 100 position. There was a noticeable drop in engine power. When the cold car starts, the engine water temperature rises rapidly and boils, and then turns normal after the cooling water is replenished.

1. The V-belt of the fan is broken or the fixed fulcrum of the generator is loose and displaced. 2.The main valve of the thermostat falls off.

3.The pump shaft is loose from the impeller. 4.

Serious leakage of cooling water. 5.The cylinder gasket is broken, the water jacket communicates with the cylinder, and the high-pressure gas flows into the waterway.

Fault judgment and elimination, if the engine suddenly overheats in the car, should pay attention to the dynamics of the ammeter, if the engine speed is increased, the ammeter does not indicate charging, and the discharge 3-5a position and "0"If the engine temperature is very high and the radiator temperature is low, it means that the pump shaft and blades are loose, and the cooling water circulation is interrupted. If the temperature difference between the engine and the radiator is not large, the cooling system should be checked for serious water leaks. If the temperature rises rapidly when the car is cold, it starts.

The cooling water boiled, and the main valve of the multi-system thermostat fell off and was stuck in the radiator inlet pipe, which hindered the large circulation of cooling water. Because this fault can make the pressure of the cooling system rise rapidly, when the internal pressure rises to a certain extent, it will suddenly impulse the main valve that is stuck and change its orientation, and suddenly turn on the large circulation water path, at this time, the boiling water will quickly rush through the radiator cover. Burnout of the cylinder gasket can sometimes cause water to overflow and exhaust bubbles from the radiator mouth, giving the illusion of boiling cooling water.

This is mainly due to the ablation of the cylinder head gasket or the crack of the cylinder head and cylinder liner, which makes the high-pressure gas run through the water jacket, so that fierce bubbles emerge.

The first step is to find a safe place to pull over, let the vehicle idle and do not turn off the engine, because the cooling fan and coolant circulation will stop after the engine is turned off, which will make the engine hotter; The second step is to open the hood, increase the air circulation, so that the water temperature drops, use the water cover to live in the radiator as soon as possible, unscrew the first gear, and then open it after the internal steam is discharged; Step 3: Do not add coolant immediately. When the water is boiled, a certain pressure is created in an airtight container.

If you open the radiator's inlet immediately after the water boils, the internal pressure will cause the boiling water to spew out, which is likely to cause burns. Step 4: Check the water tank connection line for leakage, and then check whether the cold air banquet liquid is sufficient.

If there is no coolant available in the car, you can replace it with mineral water first, but you will need to replace it with a new one afterwards. Step 5: In the face of engine overheating, what the average person can usually do is to check and add coolant.

As for other faults such as pumps, thermostats, etc., please ask for help.
