Drilling a 1/8" hole in the thermostat allows the air to escape into the radiator when your filling you system. That way you eliminate trapped air. Usually when I'm tracking down a problem with a questionable temp reading I install a tee so I can add a known mechanical temp gauge. Both read the same, it ain't the gauge. Two diff temps, you have a gauge problem.
