Engine Cooling problem
1997 Mercury Mystique 4 cylinder Front Wheel Drive Automatic 128,000 miles.
My temperature gauge is not working. Initially the gauge did not work and the check engine light was on. I replaced the temperature sending unit at thermostat housing with a junkyard unit and the check engine light went off, but the gauge still not working. Radiator fans turn on and off and seem to work normally. Gauge moves ever so slightly when the key is turned on and off, but never reach near normal operating temperature. I live in a cold climate and I can tell you the heater works great so I am pretty sure the thermostat is opening properly and the engine is coming up to operating temperature. Can a sending unit operate the fans and not the gauge? Also I just replaced the water pump, timing belt, thermostat and coolant.
