heyitsrama Posted October 9, 2020 Share #2 Posted October 9, 2020 Leaks from the fitting? Can use Teflon tape, or permatex thread sealer and see if that helps. 2 Link to comment Share on other sites More sharing options...

I used a steel bolt on my OReilly Auto radiator. Drilled a hole in it so it worked like the plastic ones. It's surprising how few options there are for those plugs, and all of the options are poor quality. 1 Link to comment Share on other sites More sharing options...

I did exactly what Zed Head did on my O'Reilly radiator too but I didn't drill a hole for draining. I have to pull the lower hose off to get the fluid out. I also used Teflon tape as Heyitsrama suggest. 1 Link to comment Share on other sites More sharing options...
