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.

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

POST 1 / ORIGINAL POSTEROriginal post

Interesting info from my indie advising last addition 3.4 996.1 using the same expansion tank (coolant) as 996.2. This is relevant as 996.1 genuine tank is £450, as opposed to genuine 996.2 £90. Northway also confirmed shiny dual IMS on 2001 year 3.4 996. (They confirmed to never seeing a 2001 IMS failure). .. and with last addition 996.1 benefiting from electric engine/frunk release seem an interesting best of both worlds bridge across early 3.4 and later 3.6. :thumbs:

POST 2Original post

996.106.057.03 in my 200q C4 3.4l as well. I wonder when they actually changed then? MC

POST 3Original post

Interesting. Could be useful. :thumb: All I'd add about best of both worlds is I think only the 98' and '99 cars had what is deemed as the best coating on the pistons, but since 3.4s rarely score, the later type coating probably isn't a deal breaker on a 3.4 and at least you have the dual row bearing in there. Would be good to get a definitive answer on the coolant tanks. £450 for a piece of moulded plastic is Porsche tax at its best. They really do know how to pee their customer base off don't they. :frustrated: Although I don't think us 996 owners register very high up on Porsche's target market. :wink:

POST 4Original post

Whats the difference in them anyway? Can us early owners not just use the later tank?!

POST 5Original post
