Dear KK:  I have a 1997 Olds Aurora.  I have been having
trouble with it overheating.  I can't seem to find where the water
temperature sensor is located.  Can you please send me some kind of
information on the location of the sensor...a diagram would be great!






KK:
That sensor is on the drivers side of the rear head. Very hard to see.
It is under the coolant crossover manifold. It screws into the lower portion of
the head horizontally. It is accessible from under the hood. It screws into the
side of the head and points toward the dr. fender.
But, I am concerned that you want to replace the sensor for an overheat
condition.
In my experience, I have not replaced many (if any) temp sensors for this.
Most overheating conditions are caused by cylinder head gaskets blown, low
coolant from a water pump or radiator leak (at the passenger side).
