I drained my radiator by removing the drain plug, let the fluid drain into a pan and put the plug back in with thread sealer on the threads. My radiator wont stop pouring coolant out the plastic drain spicket that is right near the plug itself, the one that points down to the ground. I have a plastic drain plug and a Dorman brass plug, no luck at all with either. I'm not getting any leakage coming out the threads of the plugs, tried them both. I'm stumped on how to stop the leak. Any help is greatly appreciated, thanks!
