What kind of sound does a bad water pump make?

Answer

Bad water pumps can be a pain but if you pay close attention you can hear if the pump is starting to fail. You should never be able to hear your vehicle's water pump if it is functioning properly. When a water pump starts to fail the bearings inside will start to make noise. It could be a rubbing noise. You might hear a grinding of the bearings rubbing together. Or you could even hear a whining noise. Any strange noise coming from under the hood is not a good sign and should be checked out by a mechanic.
