Actually, the green is to see how low the level is if you can't finger the level on the upper one (so I have been told).

Another reply I have received else where is the upper hole is the fill and fluid level hole the middle hole (green arrow) is a place where they can install a temp sensor in some applications, the lower hole is the drain.
