No, if you have air in the coolant system, turn the heat or fully, fill the radiator, and run the engine till its warm. When the thermostat opens, the coolant level will go down. With the radiator cap on, squeeze the hoses to pump the coolant, and top up as needed. If you still have air (or worse, bubbling coolant) you problem is a blown head gasket.
