Coolant Temp Sensor Question

Ok I know that a Coolant Temp Sensor tells the ECM if the engine is hot or cold to adjust the fuel supply but can it also check your coolant level? By this I mean does the sensor know if it is submerged in coolant or not?

The truck I'm asking about is a 94 Sierra with a 350 TBI.

I'm asking because I'm sure many of you have seen my posts about the stalling issue I have been having at start up, and I just changed my water pump since it was bad and I have not had the problem since. I'm hoping that this is finally it but I don't understand how it could be.

I'm just happy it's working, but still curious...

Thanks Again!

  And there aren't any "bellows". There are solid plastic doors the actuators move, which largely seal just by themselves, and then have a strip of foam around the edge to better seal the door. The foam does deteriorate over time, but this is unlikely to be a significant cause of the problem.

  are the heater controls set for hot or cold air? If it's set for hot, and say, to get air from outside the cab (vs recirculated air), even w the fan off, air will get pushed through the hvac system, over the heater core and into the cab. Switching it to cold will reduce the temp to whatever it is outside. Switching to recirculate mode (which may mean switching to vents or whatever, read your owners manual), will reduce the amount of airflow through the hvac system.
