I disconnect one of the heater hoses in the bilge and pump RV antifreeze through the heater core until I hear it returning to the block, then I blow air through it.

I disconnect both hoses and blow air through it, then let dry with one hose pointed up to let any additional evaporation occur. After a few days, it should be dry enough.

I just did it for the first time this weekend. When I ran the anti-freeze through the engine (5 gal), it made it all the way through the heater lines as well, so that made me feel good about clearing water out. I disconnected both hoses, noticed that there was red on both ends, and blew through one of the ends to get the antifreeze out of the hose.
