From what I have learned aobut cooling system leak stoppers, such stuff
provides temporary relief at best. The sealed leak won't stay sealed for
long. And, on the really negative side, these sealers also tend to seal
where it's not desirable - such as the small passages in radiators. If
you use this stuff, expect difficulties later. Maintenance will most
likely include repairing/replacing the radiator.
