blown head gasket
There is a kit you can buy that has a dye in it, now you hook the piece up on to the radiator fill cap and suction some of the fluid out. The dye is blue and when it mixes I blelieve it turns a colors from blue (the color of the dye) to another color( I forget the color) but anything other than blue you got problems. Sorry to be vague but the tool cost 60 $$ we got ours from Snap-On guy but you may be able to get it from an auto parts store. Good Luck !!!!!
