The AOS is plastic and has anti freeze running through it to prevent it from freezing.

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.

POST 1 / ORIGINAL POSTEROriginal post

I pulled into the gas station yesterday and noticed coolant leaking from under the car. Quite a bit, not but certainly not a minor leak. I figured it was the water pump. Temp was ok so I drove it to a nearby parking lot (drove fine). Had it towed to my Indy who just called to say the water pump was fine but the AOS is toast. I am a mechanical ingmoramous so the question is, does this make sense?

POST 2Original post

check coolant expansion tank- usually drips over left exhaust and sometimes leaks intermittently

POST 3Original post

That is how my AOS failed. It was leaking water too. Was not a cheap fix either. About $1200 at the dealer IIRC. That included towing too. What sucks is that I just changed my clutch out 6 months ealier. Should have replaced the AOS while they were there.

POST 4 / ORIGINAL POSTEROriginal post

Thanks for that. I trust my Indy but everything I read about AOS Failure talked about smoke from the exhaust, rough idle and possibly CEL. I experienced none of this and read nothing about coolant leaking. $1014 out the door. Oh well I guess it was bound to fail sometime!

POST 6 / ORIGINAL POSTEROriginal post

Quotes source post: 9490016

Yup. Quite a bit.

POST 7Original post

The AOS is plastic and has anti freeze running through it to prevent it from freezing. It can certainly crack and leak fluid, as can the hoses that are carrying the coolant.

POST 8Original post

the coolant that runs through the aos is to cool down crank case exhaust gas going to the intake..... where is the leak coming from? if its on the exhaust (driver side), its the tank... if its towards the rear of the engine, its the aos.

POST 9Original post

The 996 AOS has coolant passages.. It can fail and leak water~

POST 10 / ORIGINAL POSTEROriginal post

Quotes source post: 9490232

Kind of both acutally. More toward the rear of the car but definitely on the driver's side. Car has 54K on the clock so I guess its time. Better now than later, like 100 miles north of Phoenix on my way to Flagstaff!
