Dex-cool will give a sludgy appearance at the neck of the radiator, just wipe it out.
How many miles on it?
HOw old is the thermostat or the radiator cap?
Your info makes me wonder about the radiator being plugged, but that is rare, but relative none-the-less.
Somewhere along the way your losing coolant.
You say" I stopped my car and steam was blowing out of the right top end of my engine".
Try to narrow down where?
