Rob, I have noticed leaks of the antifreeze throughout last winter as well. (1st winter with the new to me boat, Yanmar 3ym30, extended life antifreeze). All was fine in the previous summer. Some hoses carrying the antifreeze needed to be tightened up and the leaks went away. The coldness causes the nipple/hose seal not to be as tight as it is in warmer temperatures.
