My last water pump to be installed

[smshirk]

I wouldnt do that. Cheap water pumps can break apart and ruin an engine. Good ones can as well, but it's much more likely using one like you are considering . The next guy is not going to know. Porsche owners need to take care of each other. It is expensive enough as it is.

A $150 water pump is not likely to break apart unless it is used well beyond it's expected service life. So is one stamped "Porsche". I have an original water pump that broke up and put debris all through the cooling system. The only symptom was that the car gradually overheated.
I would have rather had the previous owner install a $100 pump at the appropriate time.
Buy a Boxster and not sure how old the water pump is? Replace it.

Totally understand your point.

But the general thinking is that the person who installs a $100 water pump would likely never do so preventatively.

I guess the thing I don't get is how many folks have claimed to have had to R/R their water pumps as 40-60K miles, yet swear one should pay a premium to replace with a pump like the pump that just failed.

Sorry, can't help myself.

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?

I mean no disrespect to dissenting opinions and I have apologized to the Porsche deity in advance of this posting.

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.
