Thank you, Neil (and I love you too, Vanagon list) -

That's *exactly* what these bands must be - multiple, regularly spaced, and attached. �They clearly weren't something floating through the radiator.

Now the question is, what in the HECK are they there for. �It doesn't matter, but I'm curious, because it would seem they COULD break-off and float through the radiator...

I can't recall if the temp sensor has a rubber seal, but here's an

IIRC, there's a rubber seal between each tank and core and this is
what I see in my pic above.

Maybe that's what you found?

Neil.
