Why does my engine make a very low swirling sound coming from radiator after I drive and park the car?

Sometimes the car gets some air in the system, with the car cold remove the radiator cap slowly and see what the level is in the radiator. Check the over fill bottle and make sure it is at the full mark. If it is low when the engine has been running a while it cools instead of coolant it suck in air. With the engine cold fill it with coolant. If it is the air in the system there may be a problem with the thermostat sticking.
