Can anyone advise what kind of service/frequency the heat exchanger requires in a universal 5416 16 hp freshwater cooled diesel engine. The engine is working fine, not overheating or causing any problems, but I want to ensure it keeps working.
Our heat exchanger was leaking, so we replaced it about 4 years ago (about 300 engine hours since then). I have regularly replaced the pencil zinc in the heat exchanger, but haven't done any other flushing or cleaning. I understand that they can gradually corrode or get mineral deposits that need to be removed periodically, but I'm not sure how quickly that occurs. I have heard that a small (1/4inch) dowel pushed through the internal rods can work, or immersing in muriatic acid can work.
Does anyone have any experience/advice to keep it working properly?
Thx.
