In addition, a simpler way to solve the blockage of the heater box is to find a cleaning garage, then let the repairman remove the inlet and outlet pipes of the heater box, and then wash the car back and forth with a water gun until the washed water becomes clear. If there is a special scale remover, the original cooling liquid can also be discharged and used together with the scale remover, and a new antifreeze can be added afterwards. If the above methods cannot be basically solved, a new warm water tank needs to be replaced.
Attachment: What should I pay attention to in the use and maintenance of automobile water tanks?
1. Hard water should be softened before use to prevent the radiator from clogging and scaling. In the case of using coolant, in order to prevent the radiator from being corroded, we should choose high-quality and long-lasting antirust coolant produced by regular manufacturers that meets the national standards.
2. During normal use, the water level should be detected at any time, and water should be added after stopping the machine to cool. When adding water, gently open the cover of the water tank, and keep your body away from the water inlet of the water tank as far as possible, so as to avoid the high-pressure steam sprayed from the water inlet from scalding your body.
3. When adding water after the radiator is completely drained, you can first turn on the drain switch of the engine block to see if it is closed when the water flows out to prevent foaming.
