Ensure the radiator drain cock is closed. Slowly fill the cooling system with a 50/50 mixture of Dex-Cool® coolant and deionized water. Start the engine. Install coolant pressure cap. Place the heater and A/C control in any A/C mode except Max and the temperature in the highest setting. Allow the engine to continue idling until the lower radiator-to-water pump hose is hot. Turn the engine off. Allow the engine to cool to outside temperature. Ensure the coolant level in the surge tank is at the proper level.
