Well I could have tried that but I thought it would leak anti freeze , the sensor/bushing screws into an aluminum block below the thermostat housing. Bad/good thing I now have and extra temp sensor because I replaced it 1st thinking that was the problem.

With a tapered thread and two relatively soft metals I'd say the chances of a leak are slim, but what I do in those cases where I wonder is only put teflon tape on the bottom half of the threaded adapters so that the top threads are metal to metal, ensuring the ground connection. Different ways to achieve the same end (started to say "skin the cat" but I guess that's offensive these days.... )
