Why does Wuling Yang Guang spit water in the auxiliary water tank?

According to your description, there are water marks near the cooling fan. The auxiliary water tank spits water. There is just a bubble coming out. It is judged that the cylinder gasket may be punctured, which leads to the communication between the waterway and the cylinder. High-pressure gas in the cylinder enters the water channel, which always leads to bubbles in the water. I suggest you check whether there is a certain amount of water ejected from the exhaust pipe when the engine is running and whether the power drops when the vehicle is running.
