Figured this out. And wow. checked the wiring diagram. The Sensor is on the engine block beside the valve cover after the thermostat housing. the Sender is before the thermostat housing and what my pic is of. I thought it was somthing else. Pulled the tab off there is some fluid inside it. Now to make sure I ordered the right part lol.
That makes sense now. I was wondering how that would work with only one sensor.
Well the Tstat bolt broke and the attempt to extract it went about as good as the attempt to take it off. This is the Lower intake manifold correct? Where would I find a new one for a good project? One buddy says junkyard and tap it for 8mm bolts instead of stock 6mm.
