1996 mystique - 2.5 L v6 duratec with 62k mi. on the clock.

Experiencing classic water pump failure symptoms as described in numerous posts.

Yesterday I purchased a duralast water pump from autozone part no. AWP-9075. It has a lifetime warranty, but comes with a black plastic impeller. I recalled a post that said to buy either metal or one with a specific color plastic, but couldn't remember the color while at the store.

Is this thing total crap that won't hold up since it's black plastic?

I sent my wife to NAPA this morning, but she said they only had plastic impellers so she didn't buy one. The NAPA website shows that the impeller is a white plastic.

Any help on this would be appreciated. I inherited this car from my parents and will be passing it on to a friends elderly parents and want to give them something reliable.

Thanks!
