I'm getting some seepage from the short water hose that connects the metal
pipe that goes from below the water pump across the engine to a metal
right-angle pipe near cylinder #2.  Since I'm replacing the motor mounts
and have the muffler, cat, and heat shield out, this should be easy, right?
 The problem is that I still can't get to one of the bolts on the pipe at
the bottom of the water pump.  It's just enough behind the crankshaft pully
that I can't get to it.  Tom's VW page says use a 12-mm wrench; I'm not so
lucky.  My bolts are Allen head.  I thought I got an Allen wrench on the
bolt, but when I turned it it just rounded out the inside of the bolt head.
 At this point is it possible to remove the water pump with the pipe
attached so I can get to that bolt?
