Re: water pump impeller

Did you remove the waterpump housing? <br /><br />Should be a plastic housing with four bolts that slides down over the driveshaft.

Re: water pump impeller

The impeller could've possibly disintergrated, poke around the water passages and retrive all the broken pieces you can find.
