I noticed this weekend that I have developed a small leak in the radiator.
At the top, on the plastic part, to the left of the cap.  I've tried
stopping it with epoxy and will try "stop leak" today.

Can anyone recommend a good online place that I can buy a "guaranteed"
replacement radiator?  It doesn't have to be new.  The car has 210K miles on
it and it still runs like a champ, but I don't want to spend an arm and a
leg for a radiator.

Any help would be appreciated.

Thanks
