Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I may have a cracked coolant expansion tank and wonder if replacing it is something I should have a Porsche garage replace or is it something someone in their own home garage can do with a modest tool chest. Thanks for your help.

POST 2Original post

You can do it yourself. There are detailed instructions/DIY over at Renntech. It'll likely take you 1-2 hours.
