Hi thompsonjdt. Welcome to the forum. This sounds typical of a leaking head gasket. If you see the coolant bubbling in the reservoir when the engine is still cool, suspect the head gasket. The best test is what I call the "sniffer" test. Your mechanic will use a glass cylinder filled with two chambers of a special dark blue liquid. Air is drawn from the radiator through the tube while the engine is warmed up and running. If combustion gases are getting into the cooling system, the liquid will turn bright yellow.
