Default 2009 Coolant Expansion Tank Crack

So is this where the expansion tanks

Common. Suncoast or Porsche will have the new part. Cheap to fix but you gotta drop the engine an inch or two.

My car did the same thing. Water pump let go. While it was in for that Indy noticed the tank.
Had it replaced at the same time.
Full coolant flush.

There have been so many revisions on this expansion tank it is hard to know if this is the most current, 996.106.157.04. Is it?

That is the same part number I used in May '17 when I replaced mine. Also - most replace the cap at the same time - 996.106.447.04

Here is my writeup on replacing mine if you want to tackle yourself. https://rennlist.com/forums/997-foru...sion-tank.html

Its not a terrible job, just a bit frustrating. The hardest part was removing/installing the coolant hose clips. You need to get one of the flexible tools to remove them.

Dropping engine is definitely required but thats not too hard. I was hoping I could just loosen the nut threaded on the mounts but you need to drop it an inch or two beyond that point. I would recommend two jacks, or putting a 2x4 across the jack point and corner of the oil pan. I only had a single jack and hockey puck on the engine jack point and the engine can tilt to one side or the other, which gets a little sketchy.

Thanks for the reply and link Bruce. Can’t wait until I can work on the car. I love working on cars and with this one there just is not much to do but wash it.

Very easy car to work on and great documentation on any project you are going to tackle. Far easier than working on my Land Rover. I went from zero to pretty invasive projects in 12 months.

Start with the oil change to get yourself oriented and then build from there. Brakes are very easy. Installing eibach springs was long, physical job. New alternator/starter cable was pretty invasive but easy job. Expansion tank was a bit frustrating but done in a day. Removing and inspecting the oil pan was a satisfying job. Clutch job my Indy helped me on and we had done by lunchtime.

Ive found every project sets me up to tackle the next one.

I would also recommend downloading a copy of the 997 workshop manual you can typically find floating around the interweb. I always cross reference that with diy posts.

Hopping along this thread because I've had a very slow coolant loss that didn't get fixed by changing to the new coolant expansion tank cap. Popped off the airbox today and, sure enough, big ol' crack in the expansion tank. I'll be sending it to my indy tomorrow for a warranty repair - I could do it myself but.... it's also 100+ in Houston and combined with the humidity makes it unbearable to be outside for any length of time.

So funny. Mine is slowly leaking in the exact spot of the above photos. This should be a sticky as it takes 2 seconds and a flashlight to spot the crack. I would advise everyone to go out and do the visual inspection.

@captainbaker - agree. its easy to miss without a flashlight. I must have looked at mine 5 times before noticing the crack.

Well my indy "pressure tested" the coolant system and noted no leaks so there was no replacement done. $200 for a bunch of nothing. Whatever. I see a giant crack and that's a problem to me. You know what they say, if you want it done right you gotta do it yourself.

Looks like I'll be sweating up a storm replacing the tank on one of these upcoming weekends.

The part number on the bag and the one stamped on the tank are different. Did they give me an older revision of this expansion tank? I hear this is the 4th revision.
