As Pat Donahue and I have experienced, a little over 50K miles seems to be
the life expectancy of an E34 M5 waterpump. I now have the third, counting
the original, pump in my car at 112K miles. As for the warning signs; my
first pump gave no warning when the bearing froze solid at about 5K rpm.
The second pump just started to leak. It was a slow leak but I didn't wait
to see how fast it would grow.
