That looks like a composite impeller - to be sure just check its resistance with a multimeter.

If you are down there it is a good time to replace the thermostat too.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Finally got some nice spring weather and been re-acquainting myself with my 01s.
Im going to put it up on the lift soon and do a bunch of maintenance of on it.
The current water pump is at least 7 yrs old and has between 40 and 80K miles on it.
A few years ago, I was planning on doing the water pump and never got around to it. I bought a metal impeller Pierburg brand water pump at the time.
It's been sitting on the shelf in my garage since. Now there is Internet hysteria (?!) about catastrophic failures of metal impeller pumps.
I am trying to figure out if I should put this one in, or forkout money for a different plastic impeller water pump.

That looks like a composite impeller - to be sure just check its resistance with a multimeter. If its the same resistance as touching the multimeter prongs together, its metal.
Great news. My memory was a little foggy. This pump has been sitting on the shelf for maybe 4 yrs.
Yeah, I procrastinate.

Do you have a new gasket? Some of the water pumps come with a felt or other type of gasket but for this one you want the OEM style metal gasket. If your original water pump is still on the car you will have to trim away the old gasket since it is shared with the oil pump housing. That is one way to tell if you are still on the original water pump when you remove it.
Lots of good details here:

If you are down there it is a good time to replace the thermostat too.
Good luck with your project!

Getting the same threads within a week of each other, almost to the letter, is brutal. It's common forum etiquette on every forum I've ever partaken in. Use the search function first. If you think I'm brutal you need to get some calluses.
You're the one swearing away and you are going to lecture on forum etiquette? And if you are all concerned with getting some calluses, maybe you should take your own advice and grow a calluse about all these same threads.
