Normal operation of the engine warning up is the temp will go higher than normal at first until the thermostat opens then it will return to normal. Better check your coolant level when the vehicle is cool, maybe its a little low and thats why the temp is rising when you turn the heater on. - hemicuda
I have had the radiator flushed and the appropriate fluid and level of checked. It is correct.
