I am needing a water outlet pipe o-ring for the 2.2l it goes into the head above the timing cover when I pulled it out it was yellow in color I thought it was discolored from rust and dex-cool ( to my surprise when searching on the web to find one ,a yellow o-ring is supplied with a new tube but no luck on just the o-ring)so my question is does anyone know the gm part # for the o-ring so I can try my luck with ebay and does the yellow in color mean anything I called the local gm dealer and they want to sell a package of 10 and needs to order also and not having any luck trying to match one from the hardware store( found some close but the thickness is not matching and they are all black
