Pulled something loose?

[Psycheonabike]

Hi, one of the smaller jobs I was looking forward to doing was fixing the little lights in the radiator cover. All good (see pic below).

But I noticed a leak at the bottom of the rad. At least it looks like a leak but then I suspect I may have pulled something off after removing upper fairing recently.

I know others have mentioned that they have had simar experiences and left rad or coolant caps loose etc.... Question is, what might I have disconnected when removing the fairing that would give similar symptoms?

Thanks!
