"I have 350 6ly yanmar diesel. It has been loosing coolant for some time and overheating at wot. Recently it started overheating at lower rpm's. I have checked thermostat, impeller in pump and mixing elbow. All seem to be fine. I have heard about "buildup" and "flushing" of coolant system, particularly the exhaust manifold. What should I do and how?"
