Oil Cooler Quick Disconnects Leaking

    I recently replaced the oil cooler lines (Dorman - China)but they did not come with new O-rings for the quick disconnect side. They are leaking at the quick disconnects now where they were not before.

    Are the original O-rings high temp O-rings? Do they make a new seal kit for these quick disconnects? Looks like a clear plastic ring and an O-ring.

    I am pretty sure I can't plug the holes to bypass the cooler cause oil has to go out of one fitting and back in the other. If I plugged the holes I would not get any oil flow
    --I think-

    Should I just get replacement fittings? Haven't been able to locate them locally just yet. Oreilly's doesn't carry them here.

    Thanks for the help

    There isn't anything real special about the o-rings. Not very high temp or excessive pressure. There is a kit available to re-gasket the filter adapter. AutoZone usually carries it on the "Help" section. It includes the o-rings. I need to do mine soon, I'll try to take notes a maybe a pic or two.
