Leaking around water pump mounting or shaft Play in shaft
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
If the pump is blowing breakes, there is probably a short in the pump. The well could also be ceased. If there is very little water being pumped, the well could be dry or the pump might be "shot" http://www.irrigationsolutions.com
It would leak coolant out the weep hole.
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.
Sometimes they'll emit a high pitched noise before they go bad. Is your engine running hot? Could be a bad thermostat.
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.
Have a solar powered water pump will save you on energy cost. You can order one online at www.siliconsolar.com.
Water pump shaft loose? Water pump leaking? Water circulating in coolant system?
