Water pump on my '97 just blew at 72,000 miles. Pieces of impeller guestimated to total 80% retrieved when pump removed from housing. Pieces were 40%, 20% 10%,5%, crumbs 5%. - MIA 20%.
First part of question is where does MIA go; rad, heater core, thermostat assembly??
Second part is how to get them out since these cooling systems (totally closed) don't seem to lend themselves to normal back flushing. No impeller bits appear to have come out of rad when I drained it, nor the housing when I removed pump. Although I must admit I was looking for "pieces" not "crumbs and dust".
My work is currently under-going a rain/mothers' day delay so any advice received at this time would be appreciated and could be considered for action since patient may not be closed up until tomorrow.
