Use a thermometer to check the coolant temp at engine idle and compare with the gage indication.
If the engine overheats at hwy speeds look for a restriction in the cooling system. At hwy speeds the engine needs more cooling then at idle. Check for a clasped radiator hose, plugged radio, stuck thermostat or one that does not open all the way. Might try flushing the radiator.
