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.

I replaced the AOS on my 02 986 S a few years ago and don't remember there being any coolant lines involved.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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'm a bit confused after reading the AOS technical article on this site in addition to various forum posts. Hopefully this is a simple question with a simple answer, but I couldn't find it in all the posts, etc. I read. In what scenarios does the AOS have coolant lines associated with it and why? I replaced the AOS on my 02 986 S a few years ago and don't remember there being any coolant lines involved. I was doing some research on the 996 AOS since I believe one of the vent hoses is dripping oil down onto my motor (04 C4S), and found reference to coolant lines. What's the deal? Thanks everyone!

POST 3 / ORIGINAL POSTEROriginal post

I see, thanks JFP. Is the purpose just to cool the air down before being recirculated into the intake manifold?

No, to warm the AOS up so it works more efficiently.

This is a source reference. Confirm exact model applicability in the original material.
