Thanks to all those who replied.  One of my concerns on anti-freeze
change is getting the correct anti-freeze now that VW anti-freeze is not
available.  I have heard everything from use the Mercedes Benz
anitfreeze to use anything that is phosphate free.  So, if name-brand
phophate-free anitifreeze is the way to go, then that takes care of the
major problem besides the inertisa in getting the job done and getting
my Son's help (he is one driving the can most of the time) in doing the
job.
