Check the color of the oil if it's gray you have a warped head or blown head gasket also if you fill up the radiator with the car running does it keep spitting it out, it's another sign of a warped head or bad gasket
Most likely it's a blown head gasket. Your Cadillac has a Northstar Engine. They're notorious for blowing head gaskets. Have the coolant tested for the presence of combustion gases. If combustion gases are found in the coolant it's a blown head gasket and not worth fixing. You'll be looking at upwards of a $3500 repair bill. Both the engine and transmission assemblies have to be removed from the bottom of the car for starters. There's no other way to do the job. Hope that helps! Jim
