I'd have it looked at. It could be leaking into/onto something that doesn't
Fixes like radiator StopLeak and No-Smoke (or whatever it is for worn rings)
are a joke. My grandfather put StopLeak in his radiator once, and months
we drained it for a flush and it was just mucked up at the bottom radiator
BTW, The leak was at the weep hole in the bearing of the water pump. This
a 85 Chevy Impala.
These types of products are not intended as a permanent "fix"..... they are
a stop-gap repair to tide you over and are hard to call them a "fix". In the
case of transmission stop-leak, it is a seal sweller/softener - expect an
overhaul, sooner or later, after using this type of product.
Similarly, radiator stop leak works about 50% of the time......
unfortunately, this type of product has a hard time telling the difference
between a leak and an internal passage - like heater cores.
If you feel you must use a "stop leak" product, be aware that it can be much
more costly to clean up the side effects from their use than to repair the
problem properly in the first place.
