Bleeding the radiator is the process of releasing the air that may become trapped in the upper portion of a car's radiator. Over time, air finds its way into the overflow tube and reservoir of your radiator system. When this happens, it may create air bubbles that actually block or prevent coolant from passing through hoses and tubes in your cooling system. 3 Methods of Bleeding a Radiator Open the bleeder valves. Some vehicles have a radiator bleeder valve located at the top or front of the radiator. This valve is made specifically for bleeding off air that becomes trapped in the upper portion of the radiator Elevate the car. Simply jacking up the front end of your vehicle lifts your radiator to a point that is higher than the rest of the cooling system. This will help force air pockets closed and dissipate air bubbles into the atmosphere. When elevating your vehicle, make sure that the radiator cap or reservoir tank cap is loose, to help speed the process Start the car with the radiator cap off. One of the easiest ways to bleed your car's radiator is to simply remove the radiator cap and then start your engine. Leave the vehicle running until it reaches its normal operating temperature. It may take between 15 or 20 minutes before your car generates enough heat to push out the air that has been trapped in your car's cooling system. You may find that you need to add additional coolant, as air pockets can artificially inflate coolant levels

So this will work with the pressurized tank just letting it run with cap off
