In a car with a properly working cooling system, the coolant temp should be around the same whether the car is idling or running. There should be little variation. The car should warm up to that temperature quickly after a cold start.
The temp would depend on your car make and sometimes engine size and characteristics. In general, however, it should be a little lower than boiling. For example, the normal operating coolant temp on a Jeep Grand Cherokee is 210 degrees Fahrenheit.
