I noticed some coolant on the ground under my 04 X5 3.0i. I did some initial inspection and thought the coolant sensor was leaking as I found dried coolant on the hose where it connects to the radiator. But then I noticed my A/C compressor was really wet like the water pump or lower hose is leaking on it. Anyone else every seen this and know which part was leaking? My ride has 108k so it might be time for that coolant system overhaul. I snapped some photos:
Looking down at the A/C compressor, lower radiator hose to the right looks covered in something. The color of it is kind of brown which could be residual oil mixing with the coloant on the motor, but I'm concerned its something more than a coolant leak.

Closer look at the hose and side/front of the motor.
