Roger,
      I think the major cause of this kind of problem
is when phosphate based anifreeze is allowed to seep
out slowly and evaporate producing corrosive salts.
If the leak is caught early enough, less corrosion
will occur.   The other alternative is use phosphate
free anifreeze.   gary

Subject: 85 westy water pump replacement w/ a/c and
power steering-----
done

Hello all, Yes, I've finished the job. If the estimate
for replacing a
waterpump, ect on this vehicle is $550-600, I worked
at the rate of
about$12 per hour.I have spent the last week rehabing
from the
experience.No leaks! I used JB weld to fill in the
places where the old pump ate
into my block.First, I cleaned the places w/ sandpaper
and mineral
spirits. Next, I prepared the weld(squeeze squeeze)
and applied a bit more
than necessary(push, push). I paid most attention to
pressing the weld
for good adheasion.The key was to use a full size file
to flatten the
oversized weld .One can use the edges that the
waterpummp bolts to (about
a 5 inch circle)as a guide for the file When the file
stops cutting,
job done.. No aluminum was removed-perfect weld match
to old aluminum.JB
weld keeps me on the road!
