Drain the old coolant from the petcockl at the bottom of the radiator. Based on what brand of radiator flush you purchase will determine the process. The manufacturer will have the directions on the container. Also, if you only flush the radiator, figure around 1.5 gal 50/50 mix of coolant / water. Make sure to use the proper type of coolant. DO NOT MIX FACTORY DEXCOOL WITH ANY OTHER TYPE OF COOLANT.
