Read evidence and context

Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

Fall has hit NJ. On Sunday I took my 996 out for the day. The temperature was on the cool side so I did what I never do, rolled up the windows and closed the sunroof. I hit the "AUTO" button a set the temperature. Intermitently throughout the drive I smelled what was clearly antifreeze. I would last for a minute and then dissapear. The car only has 12,000 miles. Any thoughts ? Thanks

POST 2Original post

is there a small puddle of coolant under the left tail pipe after you drive it? perhaps coolant is leaking on the exhaust which quickly evaporates to give off that smell of antifreeze? perhaps it's a coolant tank leak? i had my tank and cap replaced under extended warranty.

POST 3 / ORIGINAL POSTEROriginal post

The smell was coming through the vents.

POST 4Original post

Usually that means heater core or the lines to it.
