    The sensor you've described isn't present in any of the above photos.

    The engine COOLANT temp sensor is located in the intake manifold - no where near your description. It is in direct contact with the coolant and supplies temp data to the PCM specifically for engine management.



    You are looking for the engine METAL temp switch. It's threaded into the cast iron head and it's sole purpose is to control the dashboard temp dummy light. This is the switch right next to the #8 plug.
