Suggestion

Getting the old tank out is a real pain, it just doesn't feel like it will ever disconnect from the retaining bracket and then it's like some Chinese puzzle working out the angle to pull it out.

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.

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

  • Porsche Club GB: 1 discussions

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Yesterday i picked up a new coolant tank for my MY03 C4S from my local OPC with a mind to swap out the original and thus prevent any future leakage due to crack issues. However, I read an article last night that suggested that whilst on some 996 models this can be done without having to drop the engine off its mounts, that the C4 cars ( and Cab's ) require the engine lowering slightly. Has anyone attempted this on a C4S ? If i do need to lower the engine it's off to my specialist.....

POST 2Original post

I did this on my C4S. Yes you you will have to drop the engine and even then it is tight! I used the Pelican Parts how to guide: http://www.pelicanparts.com/techarticles/Porsche-996-997-Carrera/33-WATER-Coolant_Tank_Replacement/33-WATER-Coolant_Tank_Replacement.htm No specialist tools required. Trolley jack (to support the engine), socket set, pliers, more coolant. Getting the old tank out is a real pain, it just doesn't feel like it will ever disconnect from the retaining bracket and then it's like some Chinese puzzle working out the angle to pull it out. It went back in a little easier. That is the hardest part. Removing the pipework, emissions pump and dropping the engine down (a fraction) are all simple. Good luck
