My weird temp sensor mount

The radiator location will be just fine. .

Actually it is a damn poor location. If and when the water pump / hose / other has a slow leak overnight, and in the kind of wx where you are not using the heater.......and don't notice it went cold....the radiator location may again be high and dry, and never send 'that warning'

A temp sender should be as low as possible and still see engine heating. Intake manifold on a V8 ain't bad, for some reasons the Chev "in head" location is better. Higher the worser
