My 97 Ram radiator drain in leaking thru the small drip tube on the drain. I
tried to tighten it but no luck... still drips. If  I try to unscrew the
plug, after 1/4 turn there is some resistance to remove it. I DON'T  want to
break the thing off then have to replace the whole radiator! I think the
O-ring is shot so I ordered a new one which I'll pick-up tomorrow. Is there
a trick to getting the thing out? I don't like surprises!!

Thanks in advance,
Dave
