makes you wonder. The original I replaced had 76k oncit but was 12-13 years old. I just want to know why it’s the only motor they put it on. Everything else including the new Ceyenne’s use metal......as well as any other car I have owned.

I installed the Aluminum waterpump pulley and will report back if I have any issues going forward. One question for you DIY guys. When tightening the 3 torx screws that hold the waterpump pulley on......what wrench do you use? Because of clearance I took the 3/4 socket torx and clamped a vice grip on the hex portion of the shaft at 90 degrees. It works and there is no way to put the socket on the 3/8 wrench as there is no space. Curious what you guys use.

since you regularly wrench on these, do you know if the metal ones that Porsche switched to on later ceyennes bolt up to the 1st generation?

I just replaced mine preemptively. I used a little blue loctite on the screws so the don’t back out. It’s hard to get a tool in the tight space.
