I drive a 2003 Saturn L200... I have a leak I believe that is coming from my heater core.. If you are sitting in the front passenger seat, in the center dash, if you take the panel off there is a silver pipe, that has little black 'clamp' like rings that seal the pipe.. I have been looking everywhere for this part, but can't find it. My parents told me that it's called an O-Ring, but when I looked them up on auto sites, it looks completely different that the 'clamp' ring in my car... Can anyone help? I have anti-freeze all in my carpet!

Please and thank you

that would indeed not be an o ring--sounds more like a coupling.

Visit your nearest saturn parts dept for a replacement part

I found a photo from someone who has the same vehicle as me..
The circled part below is the part that is cracked that I need to replace.. I'm not sure that it is a coupling...

They are not both cracked, I just circled both so you would understand what I'm talking out. It's a black plastic-type ring that clamps shut around the pipe...
