How long are folks seeing their water pumps last on GM vehicles?
If you've replaced your water pump, please state year, model, engine size, and mileage when the water pump is replaced. This will give people some idea of when to preventatively replace the water pump, since when it fails, the vehicle often shouldn't be driven at all (to prevent engine damage).
I'll start with mine:
1993 Pontiac Trans Sport 3.8L replaced pump at 55000 miles
