You will see the hose clamps right where the hose breaks as makes about a 45 degree direction change and that is where the plastic elbow insert is and the drain is built into that plastic insert. Again based on the location being the lowest point in the hose this will evacuate all the water from this area. If you do not have a drain there and are not taking it off or backfilling the system with antifreeze this area will contain raw water that will freeze.
FYI this is a 2003 4.3L V6
Does that help better illustrate the location?
It's a little embarrassing - my bilge is not as clean as it should be - I need to clean it!

I 100% do not have that on my old '89, but I know my water pump got filled and flushed with AF anyways as well as that hose.
