So today my temp guage was acting very screwy. Its a hot day out, in the high 80's with high humidty so of course I have my eye on the temp guage it rises up and down almost at will. When I stop it runs up way into the hot and when start it goes almost immediately back down into the cool, less than one half way up the guage. I wiggled the wires from the sender when I was out of the car and it seemed to work fine on the trip back. Any ideas folks?? I am about to make a long trip in the rex and wanted to know if this might be anything more serious than a scewy thermometer or temp guage. Thanks in advance.
