The seahorse knight spent money to buy a water tank with no water.

The cooling water channel leaks, the radiator coolant is not filled up, and the radiator cover is broken.

1. First, check whether the cooling water channel of Haima Knight leaks water (including engine, radiator inlet and outlet pipes, warm air and hose connecting kettle).

2. Secondly, the radiator coolant is not filled up, and there is too much water in it, which can't reach the system pressure and doesn't supply water.

3. At last, the radiator cover was damaged, and the air valve was effective, so water could not be supplied.
