How to clean the water tank? Is it necessary? Is it cleaned with tap water?

How to clean the water tank, is it necessary? How to clean the water tank, is it necessary? At present, whether it is a 4S shop or a repair shop, the inside of the water tank is cleaned by a water tank cleaner. The specific cleaning method is as follows: 1. Stop the car and turn off the engine. When the coolant temperature drops, open the expansion kettle and fill it with water tank cleaner. 2. Start the engine until the cooling fan works, and then idle for 5- 10 minutes. Third, turn off the engine and remove the front bumper of the vehicle. When disassembling, make sure that all fixing screws have been unscrewed, and then slowly disassemble from both ends to the middle. Do not break the fixing buckle. Fourth, ensure that the coolant temperature is completely cooled, then discharge the tank cleaner together with the coolant, and finally replace it with new engine coolant. Note: Because the engine coolant needs to be replaced when using the water tank cleaner, and the operation of replacing the coolant requires a lot of professional tools and equipment, we suggest that you go to a 4S shop or a repair shop for treatment. Automobile water tank (radiator) is the most important device in engine cooling system. It is not only the reflux channel of engine cooling system, but also the core component for cooling coolant and maintaining the normal working temperature of engine. Under normal circumstances, the engine cooling system uses special coolant, which not only has the most basic cooling function, but also plays the role of antifreeze, anticorrosion and rust prevention. However, if the owner uses inferior coolant or adds a lot of tap water, the engine cooling system is likely to rust or scale, so it should be cleaned in time. Actually, there is no fixed time for cleaning. It's not the same as our car maintenance project. We need to proceed from the actual situation of the water tank. Generally, there will be a lot of dust and sundries outside the water tank of our car, or when the air conditioning of the car is not smooth and the engine temperature is too high, we will clean the water tank. So how do we clean the water tank? Everyone usually chooses to flush the water tank with a high-pressure water gun, thinking that this will remove the surface. In fact, this is not correct. We see that the outermost layer is covered with condenser instead of water tank. If you simply use a water gun to wash from the outside, you can only wash the dirt inside, and there is no way to achieve the cleaning effect. The correct cleaning method is to remove the water tank and clean it, separate the water tank from the condenser, wash the dirt in the gap with a brush or a high-pressure water gun, and then rinse the surface with clear water. But we should be careful not to damage the aluminum sheet and water pipe, because the aluminum sheet is easily deformed and will break with a little force. Too many aluminum sheets will not dissipate heat well, the water pipes on the water tank will be damaged and the antifreeze will leak. The answer is for reference only. 1, check regularly. If there is scale or dirt rusting, it needs cleaning. 2. It is suggested that you pay attention to it at ordinary times and maintain it regularly to increase or extend its service life. 3. If you have the conditions, you can go to the maintenance service station or after-sales consultation to seek the help of professionals. Any consumable should be cleaned regularly in a professional way. For example, cars should be cleaned regularly, otherwise they will be dirty. Check the fuel tank of the fuel gauge, refuel it to ensure it can be used, maintain it regularly, check the tire wear regularly, and replace the damaged parts in time. @20 19
