Thats what I was wondering as well.
I cant answer really, as this is what I did. I had a slow leak in the coolant. SO I flushed the system then I added new coolant and I used them big brown pellets of stop leak. So my coolant is brown... lol
I know oil will seperate from water, but cant tell in the tank.
So Im going to drain, flush with hose (no cleaner), then put in some new green stuff this weekend.
It would be rather nice if its just the LIMG. Hell I can do that fairly easy/quick now.
