Okay, just for ***** and giggles....what are the proper names of THESE sending units? The two on the back side of the thermostat/water pump housing? Top one has a green plug, bottom one is black.

So there are no fewer than FOUR sending units associated with the water level or temperature then? Because on the front is another temp sending unit plus the water level sensor, evidently......

The FC's had more sensors, believe it or not .
I think a lot of the reason is keeping some systems isolated and simpler. You could, in theory, use the main water temp sensor that feeds the ECU for everything, but you also put all your eggs in one basket - if that sender goes bad, you have backup sensors, in a way.

Usual tricks to get lower 'on' temps near 210F are recommended.
