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.

Hi Guys,
I'm trying to change myself the expansion tank but... After looking a lot of video it's impossible to get out...
I managed to remove it completely from its housing and gained a little space by removing the nut from I think the injection in front.
Any tips ?
it's as if the engine doesn't go down a few centimeters enough...
Are you completely removing the carrier engine mount bolt nuts? Are you lowering the engine such that the engine mount bolt "disappears" into the carrier? If not, while you are lowering the engine, observe where there might be any binding and temporarily address that. You should be able to safely lower the engine at least 4cm (and then be able to complete the coolant reservoir replacement). Be careful when lowering the engine so as to not break/overly-stretch anything. FWIW, I was able to lower the engine enough to complete the job on a 2005 C2S 997.1 6MT.
Hi,
I managed to lower the engine to the end of the screws. no more. Until the end of the screw is in the support in the photo.
40cm seems quite complicated to me with an automatic gearbox.
I did a little digging and it seems we have a tech article available which may be of help.

it mentions in figure 4:
With this I confirm I have the good technique to lower the engine properly.
Not enough about 2cm to be good :/ But after that the screws go out of the support and after... i think i will be hard to replace in the hole.
It's done
Finally it's easy but we need to ;
Unplug the most of the cable as possible, coolant, fuel and push to the right.
Unscrew the fuel folden cap in the front.
Low the engine to the maximum.
After that you can push the tank to the right and push it to the bottom.
You have access to the black support on the top. Unsrcew it and keep it away.
Now the tank come easily.
Put the new one.
On right to bottom.
Put back the black support.
etc...
Thank for your help guys
