Engine Room Discussions

I want to change the antifreeze and upgrade it to ELC.  I think I know the proceedure, but I don't know the how best way to drain the old antifreeze.  Is there a drain plug, or do I have to disconnect a hose.  Also, where are the plugs that I have to open to get rid of air pockets when flushing the system and re-filling it with ELC? The boat is a 43 EastBay with not much space in the engine room.

There is a plug in the water pomp (bottemside), open the cap on the expansiontank and drain the water.by removing the plug.

You can fill the engine thrue the fillingcap on the expansiontank.
