Sometimes they'll emit a high pitched noise before they go bad. Is your engine running hot? Could be a bad thermostat.
Leaking around water pump mounting or shaft Play in shaft
your car will overheat, there will be low pressure on your system.
Is there any way for the average person to tell if the water pump on their 2005 Cheve Trail blazer is going out? A mechanic told us that ours was going but couldn't tell us how he knew. Help Please
It would leak coolant out the weep hole.
You can tell by if there is a leak around the pumps impeller or the gasket. If there is a leak, then the water pump would need to be changed. Secondly if there is no pressure in the cooling system, vehicle is overheating. Chances are the impeller inside the pump is melted, the water pump would need to be changed. Last, if the bearing are worn out on the water pump which would cause unusual noise would be an indication for the pump to be changed.
Water pump shaft loose? Water pump leaking? Water circulating in coolant system?
No circulation.

There is a small hole in the bottom that is designed to leak when the water pump bearing is goin out
If the pump is leaking or making any noise it needs replacing. It is common practice to replace the water pump when the cam belt is replaced every 90,000 miles. Reason being is that the water pump is driven by the cam belt and the pump will normally not last 180,000 miles until the next belt replacement. This saves you labor costs.
Typical symptoms could include pump noise, pump leaking coolant through it's weep hole, or engine overheating. Generally when you replace the timing belt, you'll want to replace the water pump while you're around the area. This is certainly not a rule, but in my experience 100k miles is a good lifespan for a water pump.
