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.

He followed my advice and took off his one which had a part number ending in .00 and replaced it with a new one with the part number ending in .02 and it cured it!

POST 3Original post

I had the corroded radiators...ended up finding pools of coolant in front of both front wheels. OPC replaced them under warranty...and it's been fine since. Yet another fluid leak though...

POST 5Original post

Mine was a cracked header tank and it was not covered by warranty .

POST 6Original post

My brother in law used to suffer coolant loss all the time in his 996. Turned out to be the header tank cap, which is also a problem on Boxsters. He followed my advice and took off his one which had a part number ending in .00 and replaced it with a new one with the part number ending in .02 and it cured it! Its the blue cap he takes off to top up the coolant he is using

POST 7Original post

I am experiencing the same coolant loss problem! Bit of a pain on those (rare) hot days. I have been advised that both the condenser units are leaking and therefore the system is not holding the gas. However, sounds like it could cost rather a lot of money to put right. Has anyone been able to replace the condenser units themselves and then get a specialist to regas the system? If so the info will be gratefully received! Got to keep the cost down so I can afford to put fuel in the thing!

POST 8Original post

you can get the condensors yourself yes but you need to go to indy first to get degas if their is any left in system,then you can change them , front bumper off to replace .. we are currently doing the pair including aircon regas for £330 + vat

POST 9Original post

Tony Wright at Wrightune gave me exactly the same advice, get the cap that ends in 2. best des
