On a 1996 Buick Regal 3.8 ltr V6?

Check the plug in connector's connections it could be rusted or corroded or loose or the wiring could have problems but the sensor should be on the coolant over flow container.



Hope that helps and best of luck.By the way you might need to remove or loose off the over flow container to gain access to it or to even find the sensor.
