Surge Tank Cap

Just out of curiosity I decided to check the surge tank cap while cleaning the engine and found it was loose. It has probly been about a month since I last checked it and I problibly did not tighten it down all of the way and was wondering if this would hurt anything. The coolant level is at the minimum mark.

some coolant could have boiled off/out... or some nasty bits could have gotten into the coolant.
