In addition to what you see in the pic, it took out the radiator (pieces of the fan blades) and maybe the alternator (the sudden coolant bath)...~155K miles, btw. M

 

So it wasn't leaking before this happened?

 

Oh my.

 

Not enough to be seen....I was losing about a cup a month but could never find the leak.m

 

What actually failed? Based on the damage to the impeller in your pic it looks like a catastrophic failure of the pump bearing that caused the pump shaft to wobble, starting the chain reaction.

Where were you when this happened? Must've been an "Oh ****" moment. Were you in a place where you could get off the road quickly and safely?

 

That's exactly it. I'm hoping there aren't too many curly metal s;livers in the block....

 

So, the alternator turned out to be fine (for now, anyway) and I bought a boroscope and saw nothing in the block, so here's hoping I'm done with it...nothing like spending $1K on a car worth $2500, lol....
