My heater core also sloshes and gurgles (particulary at startup and first driving) and has since day one. My dealer and I have purged, pressure tested, you name it and I finally buckled that it's here to stay. Almost 50k miles now and no worse. They have told me if a problem ever develops they will take care of it warranty or not so I've learned to ignore it. Once temp gets to normal it goes away so no biggy. Never lost a drop of coolant either.
I also had an S10 that had a heater core gurgle it's entire life.
