I think this is about a waterboxer.
the w. pump is bolted to the block ..and those 3 nuts on studs are not
'the problem' ..
If anything is, it's the two allen screws on the right side lower ...
They were usually installed bone dry on the threads by someone .
so they can be rusted/stuck or in there too tight.
and ..access isn't that nice ...and being allen screws they can strip out .
I have spent up to one and a half hours on just one of those screws in a
bad case before.
going back together..I always put something on the thread ...permatex
high tack works great ..
sticks 'em nicely ...and they come out very nicely years later.
I also replace those allen head screws with hex head screws, in either
10mm or 12mm hex head.
then they are easy to get out later.
if you do the job in the car ever...
I think you have a 2.1 ....
it's an amazingly difficult job.
A vanagon guy told me how it came to be that way ..
he said VW gave their engineers 30 days to develop a water-cooled
version of their air-cooled engine ....I believe it !
either waterboxer engine , tain't easy with engine in the van.
have fun !
