That has to be all thawed out before you can do anything. You have to be very careful trying to do it by running the engine too because it will overheat quickly. You need to get it completely thawed out and drain a sufficient amount of coolant from it so you can add a sufficient amount of anti freeze and then run the engine long enough to get it all mixed thoroughly before sending back into the cold weather.
