Broken water pump pieces

Recommended Posts

So my car suddenly started overheating, to the point that the warning light started flashing and the temperature guage quickly ran up to 250. Knowing this is not good, I shut down the engine. After it cooled down, I opened the coolant cap. I heard a gurgling noise and looked under the car to see coolant flowing out from the middle. So off to work I went on tearing things apart to find the problem. I determined the fluid was coming from the water pump, so I removed it. My problem is that a piece of the impeller was broken off and obviously is inside the cooling system and possibly blocking a radiator. Does anybody know the best way to flush out the broken piece?

I hate to say this, but you are probably not going to find all the bits. We see broken impellers blades from time to time, and I'm resonably sure we rarely get all the bits out..........................not a good thing, but without disassebling the system, I'm not sure you can.

No luck on finding the part in the thermostat. Does anybody have a diagram of the coolant system, so I can determine the next place to look?
