I did some research and found out the culprit is most likelty the coolant temp sensor and the 30a fuse associated with it. Fan should start spinning on high speed within 30 secs - If not shut car OFF to avoid overheat. The temperature sensor is a 5V circuit with both ends terminating at the ECM so it can't be the sensor that's blowing the fuse. A coolant temperature sensor (CTS) (also known as an ECT sensor or ECTS (engine coolant temperature sensor) is used to measure the temperature of the coolant/antifreeze mix in the cooling system, giving an indication of how much heat the engine is giving off. The sensor that operates the temperature gauge/overheat red light is located on the top of the head, directly behind the thermostat housing on the 4 cyl., and on the 6 cyl. The coolant temp sensor (runs the gauge) and the ECT (engine coolant temp) sensor are the same thing. Hi, I have a 1996 GT and the coolant temp gauge doesn't work at all.
