Water Pump- 199x 960
On a recent timing belt replacement (my second on this car as routine
maintenance), as always I did an inspection of all the timing
components. I had replaced all tensioner, tensioner pulley, and idler
pulley last time, and had a water pump on hand, but the water pump
that was in ther felt like new. Smooth, no notchy-ness, and good
This time, at 18,000 miles of use all felt fine EXCEPT the water pump.
It felt really bad- lots of friction and a scraping noise. I removed
it and found that the entire bearing and shaft assembly had shifted
forward far enough to allow the vanes to rub against the pump's
housing! It has worn a groove in the casting all along the outer edge
of the vanes as if it had been run in a lathe. The groove was not
terribly deep (like maybe 1mm or a but less) but I was sure glad that
I use such a short maintenance interval on the timing belt!
So, if you do this work yourself, have all those parts on hand, and
when in doubt, replace them!
