One note about that, if you place it in the bottom of the radiator your reading the water temp after it's been cooled by the radiator, and your not going to get good readings until the engine warms up and the thermostat opens.
I put mine on the water outlet on the top of the engine, so as soon as the thermostat opens I know what the water temp coming from the engine is. Still looking for a place on the block or head though, reading the water jackets directly would be the absolute best place IMO.
