Vehicle is a 91 S10 Blazer with a 4.3L TBI. It seems like it has 2 coolant sensors. I know about the one on the intake manifold, but is the one on the left cylinder head a coolant sensor too? I dont think its a knock sensor since it looks like the coolant sensoron top of the intake manifold. I know what the knock sensor looks like.

if u have an electrical cooloing fan, that is the switch for it.. try an experiment, when the fan motor is on unplug the sensor and see if it quits. if so, bingo
