Yessir. Look at the pressure bypass screws just waiting to go at any moment.....rusted clear through. No wonder I smelled coolant but couldn’t see any. The o-rings under that bypass valve were both deformed especially the smaller under the top of the cap. So coolant seeped up and into the screws/holes and sat to cook for years. Tank didn’t discolor but screws didn’t last. My guess is 2010 vintage.
Thanks TheBruce for putting this together. My tank has a big ol' crack that I've known about for a few months but I've been putting off this job. It doesn't leak, though. Last night I had a dream that my 997 dumped coolant all over the road and I went nose first into concrete. Woke up and bought the expansion tank. I'll aim to do it the second weekend of Jan.
Thx EMC2 and Jeebus31. Just paying it forward. EMC your library of write-ups is awesome and I love what you have done to your black C2.
Currently researching the next project: water pump replacement. Going to tackle that in the morning as long as I can get my hands on an E15 torx socket somewhere in SF. Thats proving the most challenging part...
Parts arrived at 7pm and had tank in and filled, and motor back up and torqued mounts down in about an hour. Not bad at all. Getting tank out was kinda lame.....

Followed the DIY and successfully replaced both the expansion tank and engine mounts. As stated previously, only tricky part was getting the tank out of the bracket and engine bay. A whole lot easier to install new tank then getting the old one out. Thx for the DIY!
