The older our cars get, let's face it our 2001-2s are actually getting on a bit, the more wear/tear we find. One of the most common issues we've found on the NA 996s (and Boxsters) was the coolant expansion tank cracking, ageing and getting a slow leak. The plastic isn't of the greatest quality but just about evertime we pull an engine and look at a tank on an 01-02 996TT the tank ends up looking like the yellow one in the picture (vs the new one). Do yourselves a favor and check for nasty-looking deposits (from coolant) and/or change your coolant tank or at least check it. This one was pretty bad as you can see the two black areas are leaks/cracks. Swapping in a new one is easy, even with the engine in and cheap... Just looking out for you guys and I'm off to change mine

 

I don't even know where it is. What is the easiest/best way to access it?

 

Seriously, ive never even seen that on my car Anyway Alex, your adding some weight, get a smaller one not bigger

 

maybe you could give us some directions on how to access/replace it ourselves?

 

Sharkman,

Are you sure that isnt off from your 930 ??

This tank is located on the drivers side of the engine bay under your decklid.. It is hard to recognize because he has taken the pic with the tank upside down.

Alex why dont you take a pic so they can understand where this is located...

 

Haha.. a 930 with coolant? Say it aint so!

 

Take a look on the driver's side engine bay where you'll see the coolant fill cap Start there!

 

Dude.. I took that at 3AM. I wasn't watching Benson re-runs like you at 5pm you know! If I'd taken it the right way up then nobody would have believed me about the holes. I know you know about the holes.

 

Why don't you send me more pictures of that other "thing"?

 

There yo go fellas. Make sens now?

 

I thought they came in beige color. Thanks for the info Alex.

 

Nope.. only when they've aged

 

Alex,

What are basics for removal and re-install for this? I plan on doing it in my garage. Thanks.

 

Ditto - I'm curious as well. I had an oil/coolant intermix on my C2 and needed an engine relpacement - is there any chance this could happen on a Turbo?
