pretty simple, undo the clips and the 4 little nuts.... but why?  You probably
need to replace your water pump just ahead of the rad a bit to the right if
you stand in fron of your car.... not hard to do.... maybe about 2 hours with
a little dexterity.  Go to MB shop website and search, I gave a detailed
account there of how to do it.

Check your radiator neck... they are common to break off.... look for white
residue on hoses... radiator... to find the leak.
