No idiot, not my girlfriend's nipple...The damn drain nipple where you drain the radiator is dripping . I tried trightening to no avail. How tight do you guys have it? Also, should I go ahead and drain the whole thing and put thread tape on before I thread the plug back on? Can my radiator be busted or a quick fix? Thanks

 

hi the drain plug has an o-ring in it, its probably worn out, drain the radiator and inpsect it, orings available in almost auto parts store for a few pennys

 

so you don't need a new radiator? Just an o-ring? cause i never heard of drain plugs leaking. thanks guys!
