What should I do if the water tank of a diesel car is boiled, and what should I do if the water tank

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 boiling the car water tank.

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 keep adding antifreeze, 100 degrees Celsius is still within the normal temperature range and does not reach 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 boil, but whether it is antifreeze or water, you can't open the lid of the water tank at this time, because there is water vapor in the tank at this time, and the pressure is very high.

There are several possibilities, the water tank is blocked, or the water circulation is not good! Then there is the ignition time too early, which can also cause the water tank to boil! And the cylinder gasket is broken! Generally, the water temperature rises faster when the cylinder gasket is broken.

Does the water tank work? Clear the water tank.

1. 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 ignition is turned off at this time, the parts are in a state of expansion, and the gap between the accessories is very small, which will cause some soft metals to fall off after the shutdown, and some will 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.

2. Do not pour cold water on the engine when cooling down, which may cause the engine block to burst due to quenching. The right way is:

Put on gloves, add a multi-folded damp cloth to the water tank cover, gently unscrew the water tank cover through a small slit, wait for the water vapor to slowly drain out, and after the water tank pressure drops, add cold water or antifreeze.

3. Due to water seepage in the water pipe and insufficient cooling water, distilled water or pure 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.

4. If the water temperature is a little high when driving, you should pay attention to whether there is too much mud, cotton wool or sand 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.

When the car is driving, if you notice that white water vapor suddenly starts to emerge from the engine cover, or when the water thermometer pointer on the dashboard rises rapidly to the high temperature "H" mark, it means that the engine temperature is too high. In general, this is caused by insufficient water in the water tank, water leakage, or the tank fan does not run. It needs to be processed immediately, step one:

When this happens, the owner immediately finds a safe place to park the vehicle, but the owner must never turn off the car immediately. Keep the engine idling so that it continues to dissipate heat, while opening the engine's hood to increase the rate of dissipation.

Note: Do not do the following while the water temperature is boiling:

1. Do not try to continue driving, so as not to cause greater damage to the car.

2. Don't try to open the car's radiator lid immediately, otherwise you are likely to be scalded by the hot liquid spraying out.

3. Do not pour cold water on the engine block and cylinder head, which may cause the cylinder block to burst due to quenching.

Step 2: After some time, we check for water leaks under the car.

Step 3: Be sure to wait until the water thermometer pointer drops to the appropriate temperature position before turning off the engine.

Step 4: Wrap the water tank cover with a wet towel, then slowly open the first switch (about 1 4 turns), wait for the water vapor pressure to be effectively released, and then completely open the water tank cover after the release is completed, check the water volume and water quality in the water tank, and whether the fan belt is abnormal. If the amount of water is insufficient, you should slowly add water to the vicinity of the highest marking.

If the water tank is leaking or the fan belt is loose or broken, call the towing company's ** and wait for the tow truck to rescue.

The reason why the car water tank "boils" is generally caused by insufficient water level, water tank rust, water leakage, etc., that is, these reasons will cause the water tank temperature to reach the boiling point. At this time, the engine will have poor heat dissipation, the temperature is too high, and the expansion of parts will reduce the gap between the parts, on the other hand, it will lead to too high temperature, and the oil viscosity will be reduced, which will aggravate the wear of each part.

What should we do when the car water tank is boiling?

1.If the water tank is boiling when the engine is running at low speed, pull over immediately. Then, turn off the engine, make a safety warning, and contact the car rescue.

2.If the engine is running at high speed, the water tank is also pulled over and stopped, and safety warnings are made. It is important to note that do not turn off the flame immediately, and should idle for a period of time to allow the heat to fully dissipate.

3.Some drivers will douse the engine with cold water, which is a wrong behavior. It is likely to cause the engine block to burst, leading to serious consequences.

4.Do not open the tank lid immediately. After the water in the water tank is boiled, a certain pressure will be generated to prevent the hot water from splashing out and hurting people.

If the car water tank has been boiled, you have to stop the car immediately, let the engine continue to run, then open the hood, pour water on the cooling water tank of the engine, assist the engine to reduce the temperature, wait for the temperature of the engine to be normal, and then turn off, it is best to wait a little longer, wait for the engine temperature to drop to 40 degrees, and then check what is the cause.

The solution of the car water tank Kaishi fan pot is as follows: 1. The cooling fan works abnormally, and the fan belt breaks, resulting in a decrease in heat dissipation capacity; The temperature of the water tank rises, which leads to boiling; Go to the repair shop to replace the part; 2. The water tank failed to be cleaned on time, resulting in the accumulation of dirt and the reduction of cooling capacity; The temperature of the water tank rises, which leads to boiling; Cleaning from the mu or going to the 4S shop for maintenance and cleaning of the brother quickly; 3. The water tank lacks coolant, and the coolant of the water tank is lower than the normal value, resulting in a decrease in cooling capacity; The temperature of the water tank rises, which leads to boiling; Add good quality coolant.
