That coolintg system has to be the most cockamamy design you could come up
with IMO.  Germans apparently do not believe in the KISS principle.
Everything I see about these cars indicates that the engineers are being
encouraged to make it harder to do any normally simple repair, or to make it
so special wrenches are needed or unique parts, like rad hoses with each end
a different size.  I had a challenge trying to use a regular radiator that
you fill from the top on my 1.5/1.6NA engine in my generator.  With the
thermostat closed there was no godamned way to get coolant into the engine,
or drain it.  I finally resorted to drilling a small bypass hole in the
thermostat.  Worked fine.
