Times light trucks drive dozens of kilometers, and there is less water in the water tank. There is nothing wrong with the washing tank.

Is it a lot less at once? Will it continue to be less in the future? Possible reasons: First, you add too much water, which exceeds the upper limit water level and the water expands when heated. Then there is a water guide pipe at the water inlet, which flows out from it, indicating that there is less water. If your fingers can touch the water, it proves that there is enough water. In addition, pay more attention to the engine temperature to avoid the harm of high temperature to the body. There is also whether there are traces of water leakage at the water pipe joint. If there is, tighten it, such as the heating pipe connection below. If not, it may be the first case.
