I had one of those fan thermostatic switches with the sensor, the
instructions said to insert it into the top hose, came with foam
tape and all this rot to seal it. Instead, I laid the sensor (a
1/4" or so "bulb") in the top seam of the radiator tank, and put a
thin film of silicone rubber over it. THe thermal coupling is just
fine; it worked perfectly, was much more physically secure and no
possibility for leaking.

The one I used was under $20 from Kragen.
