Just trying to see if I can source one locally. Putting my water pump back in. Didn't cross my mind until I was putting it back in (Oring).

34.52 x 3.53 mm thickness. For 2002-2008. There’s two rings. One behind the flange and one on the end of the pump.

Thanks, nothing could be found locally. I was assuming that was gonna be the case anyway, because of the sizing.

It’s is essentially 1 5/8 x 1/8 inches. Just 1/64 over 1/8 inch thickness.

Yeah I converted it to find it in a regular fraction. But was still unlucky. I'll just order some.
