I'm thinking that using the
drain, along with rocking the engine forward and back, would get most of the
coolant out. In your case, the rust is plugging up the holes, and making
it hard to drain coolant that's above the rust
level.
Does anyone know of a
good preservative that could be used to fill the coolant passages?
How about just straight anti-freeze? You wouldn't want to use
something like oil, since it would be hard to clean
out.
Cheers,
