Water Pump Debris

I need some advice on how to get a chunk of a water pump impeller out of my engine The impeller is a composite one, so it broke into about 9 fairly large chunks, and I put it back together to see if any were missing, and it's just my luck, there is one piece about an inch in size that is MIA. I used a shop vac to suck out where the water pump was, and that's how I got the other chunks out. I also took a garden hose and put water in where the thermostat is, but just water came out, no missing chunk. I tried finding the drain on the side of the block, but I couldn't seem to locate that I guess it would help knowing how the water flows through the system, so I know which direction it would have went, and then apply water pressure the opposite direction somehow. Any advice would be greatly appreciated!

Do you have access to compressed air? You could try blowing it out, but you'll have to figure where to apply the pressure so it doesn't force it further in. I can't help you there....

Are you sure it's not in multiple pieces in the radiator or hoses?

Or maybe try hooking up a shop vac to the water pump inlet? That way it will suck whatever is in there from whence it came, rather than potentially moving stuff further inside.

I wouldn't use it for this particular problem, but as for the block coolant drain, it's under the exhaust manifold. BEWARE: the bolt is quite short, less than half an inch or so. Don't let it catch you unaware and shower you with coolant. Ask me how I know...

Any errors in this post are purely Swype's fault, not mine.
