An easy way to check the temp. gauge is to drop the bulb into a saucepan of hot water. Check the water temp. with the infra red or other known thermometer and compare it (ignition on) with the cars gauge. Then you'll know the gauges "calibration" or accuracy.
I had the opposite problem with an old "red" motor in a Holden as the temp. sender is located at the back of the engine and the coolant flow was less than the front (near the water pump) and was hotter than at the thermostat housing.
A possible cure is to re-locate the sender unit.
