Standard Procedure-Draining Cooling System 4.7L Engine

WARNING: This page is about a different car, the 2003 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: DO NOT REMOVE THE CYLINDER BLOCK DRAIN PLUGS (Fig 1) OR LOOSEN THE RADIATOR DRAINCOCK WITH SYSTEM HOT AND UNDER PRESSURE. SERIOUS BURNS FROM COOLANT CAN OCCUR.
  1. DO NOT remove radiator cap first. With engine cold, raise vehicle on a hoist and locate radiator draincock.
    NOTE: Radiator draincock is located on the left/lower side of radiator facing to rear of vehicle.
  2. Attach one end of a hose to the draincock. Put the other end into a clean container. Open draincock and drain coolant from radiator. This will empty the coolant reserve/overflow tank. The coolant does not have to be removed from the tank unless the system is being refilled with a fresh mixture. When tank is empty, remove radiator cap and continue draining cooling system.
