Read evidence and context

Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Discussions that performed work without a confirmed outcome: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Suggestion · Original poster
If the old stuff looks clean I just intend to refill, flushing several times would be nice but it seems like a performance to bleed it every time, cool down etc, job could take several days at that rate!

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.

2 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I have seen on several threads that Comma G40 seems to be the reccomended product if you don't go for OE Porsche. I checked with Comma and they recc. G30?? Gen 2 2004 car. My intention is to change it as I believe it has never been changed in 14 years and is overdue despite what Porsche say about lifetime use. If the old stuff looks clean I just intend to refill, flushing several times would be nice but it seems like a performance to bleed it every time, cool down etc, job could take several days at that rate! All views welcome, thanks.

It's Definately g30. You can fully flush out all the coolant and change to g40 but I would suggest you mark the coolant cap to that effect if you do as its designed for g30 http://911uk.com/viewtopic.php?t=126946&highlight=coolant
