rokkan Posted November 4, 2023 Report Share Posted November 4, 2023 Hello, I was doing a service on the Boxster (3.2s with Aircon) and bought a replacement serpentine belt (preventative maintenance opposed to anything failing). On doing the change over I noticed the tensioner was not correctly tensioning the new belt (OEM from Porsche) and now the tensioner is not working at all. I suspect the tensioner has failed which appears to be a common problem. I believe the failed part to be: 99710226000 (https://www.design911shop.com/diagrams/d/40830/ - item 2 if the link works). Does anybody have a guide on how to replace a tensioner on a 2005 987 3.2s? It seems well buried and I couldn't find anything via google or this site. Thanks Quote Link to comment Share on other sites More sharing options...

I watched that video this afternoon. Unfortunately, whilst the title of the video is perfect he only removes the idler pulley - he doesn't touch the tensioner.
