This thread made me paranoid enough to go check the coolant in both expansion tanks.

The difference between Min and Max isn't much. The little disk measuring device in each tank is maybe 6-10mm between the Min and Max levels:

Min _____/| Max

Both mine were showing in between the levels. I will just check each regularly.
