The water tank is made of aluminum or copper metal, the valves in the water pump are also made of iron, and the engine waterway is made of cast iron, even if it is an aluminum alloy engine, the metal and water will have a certain oxidation effect, and the aluminum or copper in the water tank is very thin (conducive to heat dissipation), if there are no proper anti-rust measures, once the metal is oxidized (rusted), the water tank may break from the oxidized (rusty) place. And too much rust will also block the waterway, once the pressure is too large, there will also be the phenomenon of bursting, the boiling point of water is about 100, but compared with the working temperature of the engine, it is obviously much lower, more than 100 will begin to boil and vaporize, the cooling water pipe thus produces bubbles, hinders the flow speed of water, and reduces the efficiency of the cooling system, and even the water pressure is too high to appear the phenomenon of bursting pipe. The freezing point of the water is 0, the frozen water tank water loses the characteristics of heat dissipation, and the lubrication of the water is insufficient, and the long-term use will make the water pump wear, if there are bubbles and even accelerate the water pump wear and tear failure.
The main function of the water tank essence is to improve the anti-freeze, anti-boiling, cooling, lubrication and rust-proof properties of the water, and this is why the water tank essence is added.

A car water tank, also called a radiator, is a cooling system whose main role is to help cool down the car. The function of the cooling system is to dissipate the excess and useless heat of the engine, so that the engine can run at room temperature at various speeds or driving conditions. First, the water tank is the heat exchanger of the water-cooled engine, which achieves the cooling effect through air convection and helps the engine maintain a normal temperature so that it can work normally.
Second, if the engine temperature is too high, the engine cooling water in the tank may boil due to the high temperature, causing vaporization to expand. Once the tank pressure exceeds the set value, the tank lid will overflow and relieve the pressure, draining part of the cooling water and preventing the cooling system line from bursting. Third, always pay attention to whether the pointer of the engine cooling water thermometer on the dashboard is normal.
Other issues, such as fan failures and leaking pipes in the cooling system, can lead to a reduction in cooling water. Therefore, when adding water to the water tank, it is necessary to pay attention to whether the cycle and quantity of cooling water reduction are normal, and repair it in time if there is any abnormality.

The water tank is used to dissipate the coolant, and all cars with water-cooled engines have a water tank.
Most cars use water-cooled engines that rely on coolant to dissipate heat.
The coolant of a water-cooled engine has two circulation paths in the engine, one is a large cycle and the other is a small cycle.
When the engine is first started, the amount of coolant circulating is small. At this point, the coolant does not pass through the radiator tank, which helps the engine to ramp up and down quickly.
Once the engine reaches its normal operating temperature, the coolant dissipates heat through the radiator tank, which can keep the engine temperature within the normal range.
If the engine temperature is too high, the engine will not work properly.
The water tank is located in the front of the car. When the car is moving, the water tank will be windward so that the coolant can cool down.
There is a cooling fan behind the water tank. When the car is not moving, the fan turns on so that the fan draws in air, which speeds up the airflow through the tank.
The heat dissipation performance of the water-cooled engine is relatively good.
Early cars would use air-cooled engines, which had their own advantages of not grinding, but were not in line with the trend.
If you drive a car with an air-cooled engine on today's city roads, the engine will overheat in less than half an hour.
Millions of car purchase subsidies.

In general, the tank should be filled with antifreeze. Antifreeze has the effect of anti-rust and low freezing point. The colder the area, the lower the freezing point, the lower the freezing point should be used. Tap water is easy to boil, its boiling point is lower than that of antifreeze, and the water temperature is easy to be high.
Tap water produces more rust than antifreeze, and although antifreeze will not have any rust at all, it is much slower than tap water, which is beneficial to the smoothness of the engine waterway. If you are in an area where the winter is often below zero degrees Celsius, then using antifreeze can make the tank freeze less easily after a night down, especially if it is a good antifreeze.

1. Automobile water tank, also known as radiator, is the main part of the automobile cooling system; The function is to dissipate heat, the cooling water absorbs heat in the water jacket, dissipates the heat after flowing to the radiator, and then returns to the water jacket to circulate to achieve temperature regulation. It is an integral part of the engine of the car.
2. The water tank is an important part of the water-cooled engine, as an important component of the water-cooled engine heat dissipation circuit, it can absorb the heat of the cylinder block and prevent the engine from overheating due to the large specific heat capacity of the water, and the temperature rises not very much after absorbing the heat of the cylinder block, so the heat of the engine passes through the liquid circuit of cooling water, and the water is used as the heat carrier to conduct heat, and then the heat dissipation is dissipated by convection through a large area of heat sink to maintain the appropriate working temperature of the engine.
3. When the water in the tank is red, it is generally caused by some rust. Unless there are special circumstances, do not add ordinary water. Because ordinary water is either salty, alkaline or acidic.
And the antifreeze oil tank lubrication protection. Choose different pH antifreeze according to different tank materials.

Due to the long-term driving of the car, the front of the water tank and the condenser will accumulate some dust, catkins and other debris, when the accumulation is too much, if not cleaned up in time, it will directly affect the heat dissipation function of the water tank and the condenser, especially in the summer when the ambient temperature is high, the engine temperature is too high, and even the phenomenon of boiling the pot. Water tank cleaner products can quickly clean any mechanical water tank cooling system, decompose the dirt, rust stains, sediment, etc. accumulated in the water tank, and remove acids in the water tank, keep the water tank clean, durable, and improve heat dissipation efficiency.
