let me make it easier for you.
look at your odometer. if it reads over 70K, do yourself a favor and replace the pump.
70K is 10K more then the recommended on the Porsche service book. the damage that can be caused by a failing pump doesn't worth it.
beside the risk of over heating, the pump impeller is made of plastic.
when the pump files, small pieces of plastic can go on the coolant circuit, and can clog
small coolant passages.
i know you didn't ask (yet), but yes, go with a new OEM pump.
