The How to use HS codes for tariff predictionsengine water tank is an important part of the engine circulation cooling system. If it is not cleaned for a long time, a large amount of dirt and rust will accumulate in it, resulting in a decline in engine performance and even failure. Therefore, it is necessary to clean the engine tank regularly. This article will introduce some methods and steps for cleaning the engine water tank. I. Preparation work Before starting to clean the engine water tank, the water in the engine cooling system needs to be drained to avoid accidents during use. Before the tank is drained, the lid of the tank needs to be opened. In addition, in order to avoid accidents, it is necessary to turn off the engine and cool it to room temperature. II. How to clean the engine water tank 1. Use detergent to clean the engine water tank. First of all, you can use professional detergents to clean the engine water tank. When choosing a cleaner, you should pay attention to whether the use of the cleaner includes cleaning the engine water tank to avoid damage to the engine.Dilute the concentration of the detergent appropriately (dilute according to the proportion on the detergent manual) and add it to the water tank. Please note that do not add too much water to avoid excessive dilution of the detergent. Start the engine so that the detergent runs in the circulation system. After starting, please allow the engine to run at high temperatures for several minutes (unless the detergent indicates the possible running time). This can make the detergent better penetrate into every corner of the engine tank. The specific running time can be carried out according to the instructions or suggestions of the cleaner. Finally, drain the detergent and rinse the tank repeatedly with water until the detergent is completely removed. In the process, it is necessary to open the water outlet of the cooling system and drain all the dirty water in it. 2. The mechanical cleaning method mainly uses high-pressure water guns or eccentric wheel cleaning machines and other equipment. It is necessary to choose a professional auto repair factory or fluid engineering company for washing.The disadvantage of mechanical cleaning is that it can only clean the mechanical and geometric parts. However, if the cleaning work can be fully done, it will have a better cleaning effect on dirt and rust that are difficult to clean thoroughly and from multiple angles. In comparison, the cleaning effect of mechanical cleaning is usually more thorough, and the impact is smaller. 3. Manual cleaning is a primitive and effective method. You can use cleaning tools such as hot water, steel wire brush or plastic brush for cleaning. First, drain the old water in the engine tank. Then, thoroughly remove the garbage, rust, etc. in the water tank. During the cleaning process, it is necessary to wet the inner wall and bottom of the water tank with hot water or cleaning liquid, and then brush it with a steel wire brush or plastic brush to ensure thorough cleaning. As the color of the cleaning water becomes transparent, it means that it has been thoroughly cleaned. III. Precautions 1. Avoid the rapid flow of water causing injury or damage to the joints or water pipes.2. Do not operate on hot engines and water tanks. Clean after the engine and water tank cool down. 3. When cleaning the engine water tank, all temperature monitors need to be turned off to avoid the cleaning liquid invading the monitoring equipment. 4. Do not pour the cleaning liquid into the tap water to prevent blocking the tap water road. 5. Precautions also include: do not pour waste and other garbage into the environment, pay attention to maintain skilled operation skills, and operate under the guidance of professionals when necessary to avoid damage or accidents caused by improper operation. In the process of cleaning the engine water tank, you should pay attention to safety and choose the appropriate cleaning method. In addition, the precautions should be followed as much as possible to avoid damage to the engine due to improper cleaning. Only by mastering the correct cleaning method can we better ensure the long-term stable operation of the engine.
