Why does the antifreeze of the K2 sedan leak occur

Hello, add too much antifreeze, the water tank is under pressure, resulting in excess antifreeze leakage, thank you for your support to the car master, I hope mine is helpful to you [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello, when the car is hot, the temperature of the antifreeze is very high, and it will leak out after being heated and expanding. 4S shop professional technician, 10 minutes to solve. 】

When the water is hot, it will swell, and it will overflow and shrink after it is cold, this is the role of the auxiliary kettle. 4S shop professional technician, 10 minutes to solve. 】

Hello add more and he will automatically drain out, and the water cycle is to have a space [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello, generally not, but adding too much will come out a little bit from the spare water ** [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Can thermal expansion overflow [If there is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello! Just like cooking in a pot, if the pot is full of water, the water will flow out when the pot is boiling, and if you add less, it will be the opposite. When it is too full, there is room for expansion.

There are many reasons for car antifreeze leakage, such as damage to the water tank, cooling circulation device, damaged pipes, inadequate sealing of the water tank cover, etc., which can cause antifreeze leakage. It is best to make up the antifreeze first, and then go to the 4S store for maintenance.

The first thing to do is to determine if the missing liquid is antifreeze. Compared to pure water, antifreeze feels more lubricated and has a higher viscosity, but it is not as lubricated as oil. Common antifreeze stock solutions are colored, and the common ones are pink and blue.

When it is found that the missing liquid is these two colors, it is undoubtedly antifreeze.

When a rubber pipe leak is found, find the leak and tie it with tape for emergency treatment to ensure that it will not leak again. If you find that the missing part of the hose is in a difficult to reach location, you can go to the repair shop in time to disassemble the cabin with a tool or replace the hose fitting directly.

The reasons for a leaking water tank are as follows:

A leaky water tank is the most common cause of antifreeze deficiency in daily life. After a minor traffic accident or a very strong bump, there is a possibility of damaging the water tank, leading to a leak of antifreeze several wide socks. Usually the material of the water tank is the water tank, which can be divided into stainless steel water tank, enamel steel plate water tank, FRP water tank, PE water tank, etc.

Severe vibrations can cause cracking of the tank solder joints, resulting in antifreeze leakage.

When a leak is found, regardless of the situation, first check the water level in the engine compartment to see if it has dropped below the minimum. If you find that the liquid is insufficient, it is best to replenish the original liquid if possible, and temporarily replace it with purified water if possible.

The main reasons why the car antifreeze will overflow are: 1. The lid is damaged: check whether the lid of the pot is damaged, the temperature in the pot is high, if the lid is damaged, the antifreeze will flow out.

2. Add more antifreeze: If the antifreeze exceeds the engraved line on the kettle, the car will overflow during driving. 3. Thermostat failure:

If the thermostat fails, the water temperature will be too high, and the coolant will not be able to enter the engine waterway for large circulation, and the antifreeze will overflow when the water tank is circulated for a small time. Extended content: 1. The full name of antifreeze is antifreeze coolant, which means coolant with antifreeze function.

2. Antifreeze can prevent the forest from being blind, and the coolant freezes and cracks the radiator and freezes the engine cylinder block or cover when the coolant is parked in the cold winter.

1. If the temperature is not high, check the water tank cover to see if it is not tightly sealed. If the overflow is leaking, the water will leak out, see if there is aging between the lid and the pot, and then see if there is aging in other places, if it is aging, you should change a pot, made of plastic, ** and not expensive, and often add antifreeze.

2. Possible causes:

1. Check whether the leather gasket of the water tank cover is in good condition, if the leather gasket is damaged, it will lead to the overflow of the water tank in the car.

2. I don't know how long your car has been running, if it is a long time, it is recommended to wash the water tank.

3. Check whether the car water pump is damaged. Damage should be replaced in a timely manner.

If it's too full, the water temperature will rise, the heat will rise and the cold will shrink, you know...

What is the reason for the leakage of antifreeze under the car: 1. The sealing problem of the cooling system, the interface of the cooling system connecting the antifreeze tank and the water tank bridge shirt is not tightly sealed, resulting in the leakage of antifreeze; 2. Pipeline problems, aging and cracking of pipelines, leakage of antifreeze; 3. The water tank is corroded, and the antifreeze is leaking; 4. The leakage is mainly around the water tank, and you can check whether there is liquid at the connection between the surface of the water tank and the pipeline. If there is a lot of antifreeze leakage, the water temperature will rise, and there will be a water temperature alarm on the car meter, so it should be checked and repaired as soon as possible to avoid damage.
