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.

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

I'm attempting a heater core change, seeing as when I use the heater I get smokey antifreeze from the vents. This is on a 2004 986 Boxster S I've got it all stripped down, ready to remove the old core but there is a sold AC pipe blocking the way. https://imgur.com/a/3HJMEB0 I don't want to loosen the pipe and vent all my refrigerant, so what it the right way to get that out?

POST 2Original post

Typical daft design on cars today…it’s an old (ish) car so I’d saw the obstructing pipe ends off in situ and remove core…if the new core couldn’t be wriggled in I’d also cut the new pipe tails and extend the water pipes….

POST 3 / ORIGINAL POSTEROriginal post

All done. There was a plastic cable tie holding the pipe in place. I didn't think that was the issue, but once I cut it the pipe had just enough play to pull out of the way. Time for lunch, then get some coolant to top up the system. Hopefully I have heating AND AC now

POST 4Original post

Was your windscreen misting up too? This is often a sign that is leaking on these, almost like when your aircon is low and won't dehumidify the cabin properly. The difference is you can feel it oily on your screen too.

POST 5 / ORIGINAL POSTEROriginal post

Yes, it was. I fixed the aircon last winter but the heater core was shot too. I've only been able to drive with the AC on the lowest temperature. Fine for summer, but needed sorting ASAP with cold weather coming.
