Ford Explorer Fluctuating Temp Gauge
Q. 1992 Ford Explorer bought two years ago, 84,000 miles. Temperature gauge moving from cold to half way and back stays cold for 5 to 10 minutes then repeats cycle again. Drained fluid and changed thermostat, same problem. Never gets too hot, has good heat. Truck now has 96,000 miles. Going nuts.
A. There was a TSB on this problem. Replace the Temperature Sender with Ford part number F1SZ-10884-A and that should fix it. It is located at the front left hand corner of the engine.
