Re: Water pump impeller broken. Help!
My power steering cooler is straight-through, nothing to catch anything. It`s a 1998 Bravo set-up. The cool-fuel system and oil cooler do have a screen like device in them. GOOD LUCK.

Re: Water pump impeller broken. Help!
The pieces will get hung up in one of the coolers or the hoses leading to them, check and flush them all. Anything small enough to get thru the oil cooler will go all the way thru and out. I also had pieces in the intake hose between the drive and the raw pump. They fortunately just fell out when I put the pump end of the hose deep in the bilge. Don't worry about pieces in your engine, if any, they are so small they will go right thru.

Hi
I have now got all the pieces out and changed the pump. As you said all the pieces stopped at the oil-cooler. It has a screen with 1-2 mm holes at the inlet. Anything that passes that , passes the whole engine.
Thanks again

This is a good thing to do anyway like your home central heating system.
This method assumes that if it is stuck on the way in it should be able to get back out. A trick I have learnt is to try and pulse the water going in by putting a kink in the hose then letting go. Do this several times. Try and collect all the parts to see how much you have. If most of the parts are large then you could assume that smaller parts may have passed through.
Hope this works it has for me in the past.
Good luck jules
Oh yes discontect the pump
ps This is why KPM developed that run dry pump
