99 Boxster/Water Pump

[extanker]

IF the pump is leaking just take it to a dealer or a mechanic you know and trust or one that wants to work on the car. if you take the belt off only run the car for less than a minute.

I'd be careful not to run the car at all unless I'm sure its the water pump. Boxsters are known to have IMS issues and could make noises before completely going out.

A handy trick I usually do to verify where the noise is coming from is to use a long metal bar (such as a long screwdriver) pressed up against different engine components, with my ear close to the outer end.

I just did the water pump on my 2003S, first I bought a repair book. From what you wrote, I got two things to say. 1) I would not tighten the bolts unless you do it with a torque wrench, it's only suppose to be 7LBS. Secondly, it there is a noise, just take the water pump out and inspect it, than when you replace it use a metal gasket from Porsche, I got my water pump from Napa Auto.

Good luck, the Boxster is truly a different animal.
