Temperature Sensors
Back to the OP, since you are taking the guage's word for how hot you are running, your Temperature Switch may be faulty. This sensor sits at the front of the head, which sends a signal back to the guage and gives you a temperature reading (this also depends on the year of your rig. From my understanding, any XJ 91+ has this sensor in addition to the Coolant Temperature Sensor that sits in the radiator). My guage does the same, reads at about the 1/4 mark, and i know that is not the correct temperature since my cooling system is all old and every component needs to be replaced. I just ordered this sensor from Autozone for 15.99 and it should be coming in the next day or two and I'm hoping this will fix my problem.
