The cooling water line is shut down; the pump is rotated, and it is checked whether there is any liquid that tends to solidify inside the pump.
1. Manual shaft turning; 2. Whether the cooling water flow is unobstructed; 3. Whether there are any cracks in the pump casing and bearing housing; 4. Whether the valves used for anti-freezing measures are in the correct position.
