Contour Enthusiasts Group Archives Forums General Troubleshooting I think my water pump is going out,,,,,,,,,

With black plastic impeller waterpump it seems that impeller failure occurs before shaft seal or bearing have enough miles on them to fail. Seal failures posted IIRC seem to be infant mortality on replacement pumps, usually with metal impellers.

Swazo:

Surely not!
Fan failure normally only detectable when car idling for extended period or during stop and go driving in high ambient temp. Did you check for impeller bits behind stainless steel cone in wp housing, was cone firmly in place and did you install new tested thermostat correctly?

Detailed description of current symptoms might be useful.
