Alberto Parga –
The sticker did indeed say 73.5 liters for the expansion tank. They explained to me via email that it was the labeling, and that mine wouldn't have exactly 75 liters either. Hey, it's the exact same expansion tank! It seems they now have to label the actual capacity. Thank you so much for your patience with me!
