Yes, after looking at mine this AM, it's pretty simple. There are two little spheres cast into the stick.

If the top of the lower one is even with the top of the filler neck, you are at max. If the top of the upper one is even with the top of the filler nec, you are at min. If the top of the upper one is below the neck, add coolant to bring it to max.

The thing that confused me is that they show the little spheres as two different sizes in the diagram. Why did they do that?
