Hello all,

I'm working on getting the vacuum pump out of my 1981 300TD, and am trying to remove the radiator fan so I can get some room in there to work with. Unfortunately, the last 10mm bolt became completely rounded off. None of my arsenal will grab onto it, (Channellocks and Vice Grips). I don't have access to Oxy/Acel or an Air Chisel. Any recommendations?
