cooling system expansion tanks

There's a small expansion tank sold for Rotax engines that fits right under the filler cap. Anybody using one? What is total coolant capacity for Rotax engines?

The expansion tank comes already mounted on the 912uls.  I think the total coolant quantity in my setup is about 3 quarts.  I have some left over after starting with a gallon.  I used the waterless NPG+ coolant, has a 375 degree boiling point.
