I have a 93 jimmy 4x4 4.3 w motor 170k miles. The digital temprature gauge is reading wrong temp says 200 degrees after sitting over night, I figure its a sensor but i'm not sure where to look. Any help is greatly appreciated.:runaround:

The temp sensor is in the driver side cylinder head between plugs 3 & 5. If you ground the terminal with the ignition in the RUN position, engine off, the gauge should read cold. With the sensor unplugged, it should read full hot.
