@Zaid - The impellers looked fine.

I'm off to workout ... be back on later.

I love this question. It's the realization that you've been doing something wrong for a long time.

"I mean, I have to add a half-gallon of coolant like every two weeks! It's getting flushed naturally!"

@JPhi1618 - Not only that you've been doing something wrong, but that there is probably something seriously wrong with your vehicle.
