2013 Edge with the 2.0L and 104K miles. While changing the plugs I found a leak in the upper radiator hose. While changing the upper radiator hose I found a transmission leak. After cleaning the area to find the source fluid started coming out around this bolt under the air box. I tightened it down and it seems to have stopped. I will be checking and topping off the fluid, but what is this bolts purpose and how can I prevent this from backing out again?
