Engine temperature gauge
Ever since I bought my 92' with a 2.3, the temp gauge hardly ever goes past cold. I installed an Autometer temp gauge, and it reads a steady 195F so I know its getting up to proper temperature and the cooling system works properly. However, I did some searching on the forum to see if the sensor is at fault, and most cases that I found were that the gauge either fluctuates or doesn't read at all, which leads to the sensor being the cause. In my case, it does read, but only a little past cold. However, when I had the truck go up to 210-215 range once, the temp gauge sat right in the middle where it should. My guess is that the sensor is faulty and only registers at really high temps. All other gauges work correctly, so I don't think it is an issue with the gauge cluster tho I am not ruling that out completely.
