Does your car run hotter at higher speeds?

Where are you at now Daniel? I'm just 3 miles off Rt. 66, 10 miles south of Litchfield. I imagine your already past me but if your not and can stop by I have a thermal temp gun and we can check the accuracy of your gauge real easy. As the others mentioned factory gauges aren't very reliable, especially when their 40+ yrs. old. I'll shoot you a PM with my ph # so you can catch me any time
