As most others would say there is a crack in the plastic end housing of the
radiator, thats why its leaking.
You will find tighting the nut does little to cure the leak. A new radiator is
the only option.
Might as well get new oil cooler lines too.
If you're talking about the actual steel oil cooler line itself as in where
it threads into the rad... They have tiny o rings around a recess in the
fitting that end up dry rotting, etc. which causes leaking. I would use
antiseize on the nut with a new o ring or some silicone high temp/gasket
maker stuff. As for the correct tool to tighten this, it's a flare nut
wrench or careful use of vice grips. You shouldn't have to turn it too hard
if the o ring is in good shape. If the leak is actually between the metal
flange and the plastic, you're beat and the rad needs to come out.
I hope this helps as I have had both the rad leak from the plastic itself
which led to a new rad AND I have also had the leaking oil cooler line fixed
with a new o ring. Get the ring o ring from the dealer as there are two
kinds and nothing else seems to fit 'perfectly'.

Martin - you were correct. I found a crack in the plastic tank - just next
to the upper oil cooler fitting. Its a shame to have to replace the entire
radiator when really just one of the tanks is leaking. I looked at having a
radiator shop replace the tank but decided it wasn't worth the risk of
having another problem later. So, I'm in the process of putting a new
Thanks for your help.
