4100 Coolant Tank Leaking...fix?

[iqraceworks]

My John Deere 4100 tractor has been leaking coolant out of the little plastic coolant tank. From what I can tell, it's leaking out of the big black plug that is in the bottom of the tank. Is there a way to fix this, or should I just replace the entire tank? Can I pull the plug out and put a bunch of RTV around it, and then reinstall it?

Thanks!
