Hola from Pacific Northwest
We have 1995 Fleming 55, with 3208t Cats (4400 hours) a few weeks back during a 5 week cruise I noticed coolant in the bilge under my starboard engine. After many trips down the engine room while under way to try to find the leak I finally found it- a pin hole in the heat exchanger on bottom on the right side (while looking aft). At start it was dripping very quickly, however 30 minutes later the leak stopped! I applied G-Flex w/ hardener to try to stop the leak but it didn't work. Someone suggested that once the exchanger heated up the metal expands and sealed the hole. The boat is 3 years new to us and was not properly maintained. The plan is to pull both exchangers and examine. Cat says they are a year out for new exchangers. Looking for sources for new exchangers.
