I think you will find reply #13 by JacksonIII is on the right track! The head gasket is allowing hot gasses to bypass the gasket and heat the water. It only happens when you ask the engine to work a little harder than normal. Harder like go a little faster. You can buy a kit to test for combustion gases in the coolant or just have a friend watch in the radiator while you put a strain on the engine. Rainmaker Ron
