Suggestion
Also food for thought when checking the coolant tank for leaks...the coolant expansion tank is HUGE incomparison to what you can see of it just by looking into the engine compartment.

If one has worked itself a little loose the leak would usually happen while the car is running (ie pulling into the garage) but quickly subside once turned off.

The typical symptom is seeing a puddle on the ground after the car has set a little.

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.

Hello, I need some advices and help if available from you all "996 experts"
I did search the archives but did not find any specific on my situation so just wondering if anyone on this board has seen this issue. I got this 2000 996 cab couple of months ago as a 2nd driver, weekend fun car. It has 29k miles so far and before I got the car, PO kindly did the 30k miles inspection for me. Car runs perfect, amazing car...
Yesterday, I drove the P-car to work and enjoy the beautiful weather and on the way back home, as I pulled the car into the garage I found a trail of coolant behind, confirmed it's not water from AC. I checked the coolant tank and cap for cracks and leak but saw nothing. With engine off there is no actual active leak on garage floor. The coolant tank is still full huh? Could it be that the coolant tank is too full and some bleed-out to release pressure? Or the tank is cracked and under pressure it leaks? The coolant leak is definitively under the tank. What can I do to diagnose this problem? Anyone input would be greatly appreciate it as I am afraid to drive the car now. The tank may burst out completely. Thanks all in advance...
-Bao.
ps. Plan to get the car to local dealer if it's still safe to drive...
Thanks Chris, I got an appointment for next Monday with local dealer. Will specifically ask them to check the coolant expansion tank for cracks and leaks.
I have the same problem - leaked twice under the muffler, but the tank, cap and under the tank are bone dry. Isn't the water pump in the area beneath the alternator?
This is the problem - very hard to see/detect - allows a 'cautious' dealer to charge you for a new pump before they find that the tank really had failed....
Of course my experience is no guarantee, but it seems to be very common and worth the first look.
Just me being cynical - but ask me how I know this!
Chris.
Another thing to check is the hoses that attached to the coolant tank. There are held on by compression type clips that may have worked themselves back a little which can result in coolant leaking. If one has worked itself a little loose the leak would usually happen while the car is running (ie pulling into the garage) but quickly subside once turned off. Cracks in the rubber hoses would also exhibit this type of leak. If the tank is cracked you have quite a severe leak as the it usually does not leak enough to see trails of coolant. The typical symptom is seeing a puddle on the ground after the car has set a little.
Also food for thought when checking the coolant tank for leaks...the coolant expansion tank is HUGE incomparison to what you can see of it just by looking into the engine compartment. It goes quit a distance back in the engine compartment and is contoured to the engine compartment wall/shape. You have to stick your whole arm (basically up to your shoulder) into the bowels of the engine to reach the back and a leak(s) can develop anywhere on it.
Bet - good write up. I didn't know that the coolant tank was THAT large!
I also didn't know that these engines had bowels. Man, you learn something everyday on this forum!
Just kidding about the bowels thing!
FYI for anyone contemplating replacing their coolant tank as a DIY, Sunset Porsche sells the tank for less than $100 (well at least they did about 2 months ago).
