Note:
WHEN it fails...! Not "if" and regardless if you maintain your car, but
WHEN it fails, you're done.

Wow. So the take away from all this is you can't use a metal impeller because it will almost immediately come alive, devourer your block, and when it's done come after you and your family.
So in summary, water pump with metal impeller = :troll:
And you can't use a pump with a plastic impeller because you won't get around the block without it shredding into plastic confetti requiring a complete tear down of the entire engine for cleaning.
water pump with plastic impeller =
