So I replaced my thermostat housing unit today with the dorman aftermarket kit and the o ring in the extra port is leaking badly. I've seen this is a common problem through research but nobody lists the fix. I have tried both o rings that came with the kit to no avail. It is only leaking from the extra port where the plug is installed. Please help!
