Just got back in from moving the A/C compressor out of the way.  As Robert,
Terry and others pointed out, it wasn't the oil cooler hose.  I thought it
was, because I was looking at the ETKA diagram, and it basically shows
everything on the same level (Note to self - Never assume...).

The hose that broke is the coolant line from the left cylinder head to the
coolant manifold - the strange one that has a 90 degree bend, and changes
size about three times.  P/N is 025 121 058M.  It split right were it goes
into the head.

A new one is on order from Bus Depot.  After I install it, I'm going to
pressure test the cooling system to make sure that all is well.  Guess I'll
have to go buy another few gallons of coolant...<sigh>
