For this tear-down I used that drain until it wouldn't drain anymore. Then I still got out copious amounts of coolant at various stages of disassembly. I am not sure what the best procedure is. David Leonard 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.
