2006 Dodge Charger Cooling system

there is a plug at the front of the water outlet housing at the front of the engine (may be necessary to install a bleeder valve on 5.7l). Install a hose(4-6 ft long and 1/4 ID clear)and route it away from accessory drive belt and place the end in a clean container.You MUST open the valve before any coolant is added to the engien or it may airpocket.Need to also pinch off the hose that connects the two chambers of the coolant bottle
