[C320-list] Coolant

[JBrown5093 at aol.com]

For the second year, the antifreeze (red) has disappeared from the overflow  
bottle while sitting for the winter. The engine is still full and the bottle 
had  fluid about half way up when cool just before storage. I can't find any 
leaks.  Several other Catalina owners (36's and 38's) say they have the same 
problem  every year. During the sailing season I don't have to add any fluid. 
Gets quite  cold here in upstate NY (18 below this winter). Any ideas? Jim  Brown
