If they are talking 24-26 inches of water (anything short of an atmosphere), it would fill the radiator, but it would not eliminate air pockets in the engine.

I would be a bit concerned that the water pump seal would be damaged at an atmosphere of vacuum. Vacuum would be a pressure in the exact opposite direction that the seal is designed to work. Can a radiator tube take 14.7 lb of force pressing on it from the outside? What about the radiator tanks? Most tanks that can hold lots of pressure will collapse with a vacuum in them.

Lots of bad things can happen it this world. It might work, but I would want to know more.
