Has anyone experienced a bad water pump without the usual outward signs?

Thanks

The original pump on mine just locked up driving one day no fluid out the weep hole never got hot before.

I'm just wondering if they don't lose there efficiency over a period of time.

Not unless the impeller rusts off. Never saw one like that, they usually leak or make noise.

mine just started spewing... luckily i was about 100 feet from work.

I have had 2 WPs ( not on the cummins) that the impeller came loose from the shaft, no outward sign, it would not overheat setting idling, but would gradually overheat going down the road.

The WP's are so cheap for these things, if I suspected it at all, I would just change it.

Thanks everyone for the replys.

Even if the propeller came off there is a back plate that would stop it. I just replaced mine, the bearings seized up on me.
