Does anybody ever pull the engine cover off, remove the belt, grab the pulley to check it for play before just replacing it based on the mileage/calendar? Usually pump bearings get noisy and/or develop a bit of play. Then the seal starts to weep before it grenades. I understand that the plastic impeller condition can't be seen without pulling it.
I am good with proactively maintaining a vehicle. X/O an expensive OEM pump with OEM antifreeze that is equally pricey just cuz seems unwarranted IMHO?

IMHO waiting 'till you have a wobble or weep is kind of like waiting until you see chunks of steel in your oil filter before you change the IMS bearing. You are fixing a problem after it has likely damaged your engine.
If you don't like the price of parts from Porsche, there is plenty of aftermarket support for our cars. Just do a little research and know what you are buying if you go to an outside supplier.
For example, Know that if you go with another brand of coolant, you need to flush all of the unicorn-derived fluid out of the system first. Avoid coolants that aren't
Phosphate and Silicate free. I don't need a "lifetime" fluid, because I'm
dumping it in the river every few years.
disclaimer: This is my unejukated advice. I get bored reading more than a page or two into the manuals. Do your own research.
