If it drained out of the overflow above the passenger rear wheel you probably had air in the system. Did you top up the coolant recently?

Without more details, I'd vote for the cap.

same thing happened to my '04 recently....loss of coolant without any external signs of a leak on the ground and no smoke from the engine....it was the infamous 'coolant expansion tank cracking' issue that affects a very high percentage of the 986's.....the coolant was leaking out of the cracked expansion tank and settling in the pan under the carpet in the trunk...the pan is deep enough to contain the coolant before it spills over onto the ground.....

good luck...

Happy,Happy!!!

I never thought of such an issue. The tank has to be the problem. Now to buy one and drive 700 miles back to where it sits. Cost me a car rental to get home but this solution makes me happy happy. Thanks to all of you who responded. Nice people!

If it is your tank, thatís not an easy solution... easy diagnosis, but swapping a coolant tank in these things isnít a quick job unfortunately. There are a few articles on the matter and a couple are quite creative. Itís also easy to check. Your trunk carpet might be wet, or wet underneath.

I'm going on a hope and a prayer but it seems likely to be the problem; no smoke, no oil problem and when I puy anti-freeze in it magically disappeared in a short while. ! didn't know about the area beneath the trunk holding a large amount. I read the how-to's and shouldn't have a problem with the repair. I'm going to post a query on OEM or after market tanks. Thanks

Don’t go aftermarket on the tank has usually been the response to tank replacements.

OEM is the only way to go. You'll find that advice prevalent upon these pages.

However... if you choose to go aftermarket please post on You Tube both of the videos of you installing the tanks. The first video should show your step by step process when installing the aftermarket.

The second video can be the same "how to", but with the OEM tank which highly we recommend.

Cheers!
