If there's a stop leak Product in the cooling system, get it out of there. This is definitely a coolant circulation problem or possibly a blown head gasket. With the engine cold pressurize the cooling system with a pressure tester. Start the engine. If the needle on the pressure tester bounces it's a blown head gasket. If that checks out ok use a chemical cleaner to flush out the cooling system. Hope that helps! Jim
