Reason for the Flow in the Hood?

Hello friends, it attracts my attention for days, there is wetness in the front left hood, I check the radiator water, there is no shortage, where can this wetness come from ??

this is not a trace that is formed from the inside out, but from the outside, the oil inside the axle bellows may have spread like this, or if you have passed over the oil, it is necessary to check the bellows first, then clean and observe the hood for a day or two. errör 2013-08-22 21:29:20

The deformed part of the bellows caught my attention, could it be caused by it? I did not go over any tar but as you said, it will be necessary to clean and observe the area for a few days.

air conditioner water flows, air hot engine water may drain from the expansion vessel discharge, water is wiped on the wipers while it is going on the road, its expenses can go from there to the night, it may be from there to the ground ... just get excited but follow it anyway.
