    It could be the coolant expansion tank cap overflow hose. Tug it from the top and see if it’s that hose you are seeing.

    But coolant is not so dark, it looks more like oil...

    then it could be your half shaft boots, there might be a tear on the boot and liquified grease is coming out.

    or.. Does it smell like transmission fluid? I had a leak in that area a few years back and it was one of the gearbox oil cooler lines that was weeping and dripping down the outside of the black coolant overflow tube in your picture and onto the floor.

    Just taste it; that will tell you straight away what it is.

    For the love of god, TOUCH THE PUDDLE WITH YOUR FINGERS and then you will know if it's oil or coolant or trans fluid. Why you would take pics of the puddle and then post them here instead of just TOUCHING THE PUDDLE is beyond me. Get it together please.
