serious answers PLEASE! We need to replace it and can't find it. We were told where it was but that turned out to be the fan sensor. Any help is appreciated but don't tell us to get the book on the car or talk to a mechanic - who in the heck do you think told us where it was in the first place?!
 
There are two, on at the upper hose to the radiator in the water neck and the other is in a fitting at the other end of the block in the head. One will have two wires (this is for the ECM) and the other one wire (temp gauge).
