Hey everyone. I finished up the winterization of the engine and on-board systems in the latter part of October. In doing so, one additional thing I did was added coolant to the resovoir in the port locker. It was down below the ADD line and so I brought it up just over the ADD line thinking this would be a good place to be to start in the spring. After being away for about 4 weeks, I went to the yard yesterday to check on the boat. Mainly the Fairclough cover since we have had some winds here on the southeast coast of Massachusetts. The cover was fine I'm happy to say.
When opening the hatch boards I was greeted with red fluid covering a large spot on the galley floor and emanating from the engine cover. Uh oh...what now I thought.... I pulled the engine cover and it was evident that the fluid was from the coolant tank. I checked up in the port locker and sure enough it was empty. The engine bilge area beneath the engine had a large amount of fluid in it. I could NOT find an obvious (still dripping) spot where the fluid may have leaked from.
We have had some very cold days and some very warm days here in the northeast. As cold as 23F and as warm as 70F during the 4 weeks I was away. It seems like the change in temp may have caused the fluid to leak from a hose somewhere, but I couldn't find a leak.
Has anyone experienced anything like this? Where are the typical culprits? (the pressure cap seemed dry), as did the return line tubing at the nipple near the pressure cap. What am I missing?? See attached pics....
