A water pump on any car is going to fail when it is it's time.
One of the local owners had his replaced 2 weeks ago. I asked him to save me the old one so I could take it apart. When I got it it was easy to see the bearings failed. I wanted to take the pump apart but there is no way I could get the pulley off.
Yesterday I was at the local dealer talking to the mechanics I know. One of them was working on a 2000 Boxster. On his bench was a broken water pump that he had just replaced. The pulley was off the pump. I asked him how he got the pulley off because I was not able to.
Oops. The water pump shaft for the pulley had snapped. That is one stout shaft. Never see that happen. Took a picture of the pulley.
Trivia. 2 of the mechanics said a few years ago Porsche started using a pump with a slightly smaller pulley. This makes the water pump spin faster.
