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.

POST 1 / ORIGINAL POSTEROriginal post

Hoping the rennlist experts can help me one more time. Other day smelled coolant, got my 996 up on a lift and found coolant leaking from the drivers side rear of the motor (so side of the motor where tranny bolts up) for the life of me I cant tell what the component is that the plastic hose seems to be going into. it looks like I have a small amount of coolant seeping from the plastic line. Is this the oil/air seperator? or am I completly off base here. I have attached a pic. Can anyone help and point me in the right direction?

POST 2 / ORIGINAL POSTEROriginal post

sorry guys, the pics are turned a bit. should be turned 90 degrees to the right

POST 3Original post

have your cooling system pressure tested to locate/identify the source or cause of the leak.

POST 4Original post

That look exactly identical to my AOS failure. I mean IDENTICAL! Based on the picture you provided I would venture to say its the coolest line on your AOS

POST 5Original post

I hav the same problem as well. Here's a link to the part: http://www.autoatlanta.com/porsche-p...-05/104-10.php Im getting mine fixed by my local Indy who estimates 4-5 hours and the part was $102 from my local pcar dealer.

POST 6Original post

My 99 went in to my indy on Wednesday with same location coolant leak, AOS failure.

POST 7Original post

+1, looks a lot like AOS. Good luck with everything.

POST 8Original post

I seem to have a similar problem that somewhere there are some drops of coolant, so AOS could be at fault? one question, what does the AOS on 996 have to do with coolant? sorry for the incompetence.

POST 9Original post

Quotes source post: 12105033

Coolant runs through the AOS to avoid ice up at sub zero temp. If you look at the AOS, you will see two skinny barb connections. Those are hooked up to the coolant lines.

POST 10Original post

While you're sure where it is coming from in case any forum-mates have a leak you can't find, replace the reservoir cap first. They're dirt cheap and tend to fail frequently.

POST 11Original post

while the part will be ordered the coolant warming function will be removed by connecting both ends together, that will also show whether there are any other leaks, hopefully no
