With the arrival of summer, we have to face a common problem in truck transportation - high engine temperature. The cooling system, as a key link in the five major systems of the engine, is directly related to the safety and efficiency of the truck. In this season, the water tank, as the core component of the cooling system, needs our special attention.

High engine temperature is not uncommon during transportation, and it has even become a problem for some truck friends. The root cause of this problem is often the radiator, which is what we often call the water tank. Therefore, in order to ensure the normal operation of the truck, the maintenance and care of the water tank is particularly important.
Water tank external cleaning
In summer, when catkins are flying, thick catkins often adhere to the water tank and the intercooler and condenser in front of it. In summer, it is necessary to frequently clean up the catkins and other debris adhering to the outside of the water tank to maintain a good heat dissipation effect. If the water tank is not removed, some catkins that are not firmly attached can be directly removed by hand. After that, you can use a flexible hollow hose connected to the mechanic's air pump to blow air from the engine side to the water tank.
Pay special attention to the direction of blowing from the outside of the water tank to the engine, avoid blowing directly from the front of the water tank to the engine, and ensure that the debris is always covered in front of the water tank during driving, so as to blow away the debris more effectively. At the same time, be careful to avoid touching the heat sink to ensure that the heat dissipation effect is not affected.

Water Tank Internal Maintenance
Summer is the peak season for water tank cleaning, but there is a misunderstanding that needs to be clarified. Correctly selecting and using antifreeze to maintain the cleanliness of the inside of the water tank, regularly cleaning scale to prevent clogging is the key to ensure the normal operating temperature of the engine. If your vehicle has been using genuine antifreeze that meets national standards, it is usually not necessary to remove the water tank for cleaning. This is because high-quality antifreeze
Not only has antifreeze and anti-boiling functions, but also has multiple functions of anti-corrosion, anti-rust and anti-scaling.
Although its function may gradually weaken after two or three years of use, it will not cause blockage inside the water tank. Regarding the choice of antifreeze, the production cost of national standard antifreeze is about five yuan per liter. If there is antifreeze on the market with a price far lower than this, such as a small barrel of 9 kg at 50 yuan, it is likely to be a low-quality product, because the merchant cannot sell it at cost price.
Next, let's talk about the cleaning inside the water tank. A water tank that has only been filled with water for a long time without changing the water may form a layer of scale on the water pipe wall of the radiator, which will affect the heat dissipation effect of the engine and cause high temperature problems. Ensure the normal operating temperature of the engine. If the water tank is blocked inside, it is recommended to seek the help of a professional master for cleaning. During the cleaning process, in addition to using steel bars to penetrate the water tank, water tank cleaning agents for descaling, decontamination and rust removal will also be used. But please note that this cleaning agent is somewhat corrosive to the water tank and should be used with caution. The water tank on the truck should be soaked for a maximum of one or two minutes, and then it should be rinsed with clean water immediately to avoid damaging the water tank. Although the cleaning process is slightly complicated, the effect after cleaning is significant, and the performance of the water tank can be restored to its original state.

Maintaining the water temperature at the best state is crucial to the engine, because it not only makes the engine powerful, but also improves work efficiency, saves fuel, and extends the service life of the engine. However, it is not uncommon for the engine to have high temperature due to water tank problems, and it even occurs in some new cars, especially on long slopes, plateaus and high temperature areas. This phenomenon is more prominent. For these problems, the best solution is to increase the cooling area of the water tank to ensure that the engine can maintain a normal operating temperature in various environments.
