my radiator has a leak, i think in the flush vlave or whatever (the hole on the bottom left corner from a drivers seat point of view). shoud i get a new cork, and flush the system, or use that copper sealer stuff. also, whats the deal with these sealers?

No sealers besides the OEM tablets sould go into your system.

And I would only get it from the cadillac dealer...... Although, the cadillac dealer is in spitting distance of me!

BUT..... I would not think that the sealer stuff will stop a leak that big (relatively speaking).... I think that stuff is moreso used for stopping/preventing leaks before they start <making a hole to leak from> or start leaking.....

I've found that good ol' black pepper stops the smaller leaks and (don't laugh, this is no joke) a green banana will stop the larger ones. These are some of the tips I've picked up from a variety of old timers.
