My temp gauge starts out all the way on the left in the cold area, over the course of about 15 minutes it will make it to the middle. By the time I am driving about 1/2 hour it moves all the way to the hot side. The car runs great, and I verified the actual temp with a Fluke digital thermo that the highest reading I got at the top radiator hose was 193 degrees. QUESTION ONE, is there any way to adjust the needle reading? Could you put a resistor in the line to adjust the actaul reading back to the gauge? TWO, I can't find a replacement gauge anywhere, like CJ etc. Anyone know where and if they are available?
