Water pump and coolant tank replacement?

Hey all, 2000 996 C2 Tip with 102k miles. Noticed a slight turbine sound over last couple of weeks. Not just at start up. Matches engine RPM w/ or w/o transmission in gear. Listened to the engine running but couldn't audibly locate it. So I suspect a pulley somewhere on the engine. Anyway, I was thinking that maybe I should do some preventative maintenance on the moving parts. So I was thinking of changing the water pump and coolant tank. No signs of leak that I can tell and temps seem to be okay. Since I live in a rural area my main concern is having a failure then being stuck. So I look up parts on the internet and find them for about $600 (w/p, gasket, thermostat, coolant tank, new cap, some rad fluid, polyrib belt). Read DIY on W/P and coolant tank. Although kind of a PITA, doable. Dealer said $980 for W/P and $730 for coolant tank but DID NOT recommend I do this unless I am seeing it leak.

Thoughts? DON'T fix what isn't broken or FIX it before it lets you down in BFE!

You might also want to check the Alternator since that too has a moving pulley that could also cause the sound you are refering to. With 102k miles and living in a rural area....why not. I would change it since it is not that hard to do anyway. Good luck.

Turns out it is the alternator.
