Seems like lotsa listers got "defective" new water pumps. Mine is a Graf
(made in Germany, new build, blue box). I replaced the _first_ new pump
after 75 miles cuz it was noisy. The new new pump is the same way. It
now has 18000 miles on it, and still makes the grind/whine/irritating
noise at ~1050-1100 engine RPM. Seems to be a "feature," a la Microsoft.
