Moving water can't freeze. Not really an issue if the engine is running. If you heat the al water in the tank the injectors won't pick it up. They like cold water.
Besides....it will live in the roundhouse when not in use. And if you store an engine for a longer period of time it's best to drain and winterize.
As has been said before. Just because 493 burns oil....it's just another engine. It will be in regular rotation with the other engines after all the break in and debugging is done
