Interesting problem. I have a small John Deere tractor with a 23 hp Yanmar engine. When the temperature is hovering lower than minus 15c a small amount of antifreeze leeks out onto the garage floor. I've always wondered why. There's little change in the overall volume of the cooling system and all summer long there's no issue. Maybe a Yanmar thing.
