My totally stock, 99,500 mile 95 GT convertible sat for 6 years while I did a bare metal re paint. I obviously only worked on it part time, but it is now done. The water temp gauge was going to the top when I first started driving it again this past week, so to be safe, I replaced the t stat with a new Ford stat. I tested it on the stove to be sure it opened at 195, and it does. Gauge still did the same thing. So, a new radiator from NAPA, back flush, and fresh coolant. Now it takes much longer, but it still creeps up to the top of the gauge, and even the service engine light comes on. So yesterday I bought a infared thermometer, and while the gauge was up high again, it showed no higher that 199 degrees. Is there a some kind of sensor that controls the gauge that could be bad? The oil pressure also reads higher than normal too. The car runs perfectly fine, hasn't boiled over, and, with the cap off, I'm seeing great flow across the top of the radiator. Any help is appreciated!
