Feel better that it is replaced "while I was in there."

I also replaced the thermostat housing and the thermostat, but didn't use the lower temp version (I bought TWO of these but they both were not really the 160 degree part and ran out of time).

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.

Replaced my water pump preventively this weekend on my 2001 with 77k miles. To my knowledge the pump was original. It looks flawless, no degradation of the impeller. When I spin the pulley by hand the bearing sounds a little noisy, but it might be my imagination. I'd probably say it was fine to keep using. Just thought I'd share since some folks seem to think these are guaranteed to disintegrate every X miles or Y years and embed impeller parts throughout the cooling system.
Also replaced the thermostat and all idler/tensioner pulleys, all original. The new 997 pulleys are plastic and use aluminum spacers instead of steel, so a few grams saved there. The big 24mm nut on my tensioner was a little rusty so I wanted to tackle all that junk before it gets harder to remove.

Similar experience replacing a water pump this spring on an '01 986 S with 40k miles. Impeller was perfect, bearing was starting to get a bit stiff but not in need of immediate replacement. Feel better that it is replaced "while I was in there."
31 known failures and counting. After all the OCD P car crowd replaces all the parts on their cars that have yet to fail with new ones the 32nd known failure will emerge.
Selling parts for these cars is a very big and profitable business!
Just say-in.
I used a Pierburg pump that was a Porsche part (has Porsche part number). I also replaced the thermostat housing and the thermostat, but didn't use the lower temp version (I bought TWO of these but they both were not really the 160 degree part and ran out of time).
