Unhappy 06 525i radiator Swap

So, as it appears I am just another struck by the infamous BMW radiator... I recently had a low coolant notice appear, filled it dropped the under belly plate, and waited... Sure enough I have noticed that it is leaking from the front driver side. I removed the hood latch area and opened things up to look around. I cannot see anything unusual from the top but from the underside, I see its dripping from the bottom driver side of the radiator area. It appears that the radiator is encased in a plastic molding of about 1 inch thick..? Anyways it appears this cant be removed from the bottom, and before I ordered a new radiator I figured that I would see if anyone has any ideas to pin point the leak besides pressure, and if anyone knew of a way that I can completely access the radiator itself from the bottom. Also if I do go ahead and remove/replace the old radiator, does anyone have any advice on tools/technique beforehand or know of a good video?

If you want to DIY, get the Bentley manual. I don't know of a E60 DIY for this, but there are E46 examples (E46 fanatics has one, I think) and the job is pretty similar. Good time to do the hoses as well. Not hard.
