If either one required removal of the other to replace it, I would agree.
Both are a pain to replace, so without due indication of a problem, spare
yourself the pain.  Just be careful not to contaminate the system during your work
and flush the system with plenty of fresh fluid before you button it up.
Anyway, since by now most vans have had at least one previous owner, there is a
possibility that the properly functioning cylinder has already been replaced.
