Folks,

Checking why my radiator fan wasn't coming on, so removed and tested the radiator temp switch (the large module that screws into the radiator and gets power to the fan when the temp is high enough). �Inside the radiator was what seemed to be a rubber band, sticking into that side channel, as if it extended from the coils. �It stuck out far enough out so I could easily hook my finger in and pull. �It snapped, and I removed a 1.5" chunk of (seemingly) rubber. �Feeling around again, there was at least one more, another inch down, feeling the same - as if it was supposed to be there, but had extruded from the coil. �If I'd had x-ray vision, my impression was that all the way down and maybe up, it looked like the edge of a spiral notebook, except with rubber...

What gives?? �I have a radiator on order (just in case) this radiator should be swapped-out.

Thanks,

David
