Also take these two things into consideration before worrying about your temp guage. Somewhere in the owners manual I read that the temp gauge doesn't start to calibrate and read correctly until you get to speeds over 30 MPH. Also, here's the big one. Most bank sign thermometers are mounted 6 to 8 feet above the ground. Thats the standard to keep radiating heat from the ground from interfering with the actual ambient air temperature. Your temp sensor is mounted maybe 4 feet high and you're always on asphault or some type of pavement. The temp guage is almost always going to read higher than a bank sign or weather sensor when it's extremely hot out. Hope this helps.
