Reply to "Temp Sensor"

After a bunch of checking, I found similar things. My temp gauge as it turned out apears to actually be bad. It will read up to about 100 degrees, but that is it. I did find that the ground was not great. If you take off the sensor wire and ground it, it will peg your gauge. This will prove that your wiring is good, and also lets you know that you gauge works at least somewhat. The next step was to solder a wire from the side of the temp sensor and ground it to metal (valve cover in my case). This will prove wheather the ground is good or not. In my case the temp sensor did the same thing thus telling me the sensor was bad. Now the point of this rambling. Since my radiator cap had been regularly over flowing, it caused a build up of grime between the pressure can and the band that holds it on the car. This is the only ground a stock system will have. I recommend that everybody check and clean/sand the area where the two clamp together. This should help on that irratic reading problem.
