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 2Original post

NO vario cam PLUS is a much more complex system and requires a new "brain" and wires - it has been done but is NOT trivial

POST 3Original post

If you have a model year 2004 car your engine is 3.6L.

POST 5Original post

DOH...my bad...04' is 3.6 sorry, I didnt read that at all

POST 6Original post

Vertex auto offers a headers swap with core as a cheaper option. You should find out exactly why coolant is mixed in first.

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