2. If the radiator is full, drain down the coolant to allow enough capacity for BlueDevil.

3. IMPORTANT: POUR SLOWLY! Start the engine while cold, then turn the heater on max. With engine idling, SLOWLY POUR BlueDevil into the radiator. (If the vehicle does not have a radiator cap you may pour BlueDevil in through the top radiator hose. Take 1 minute pour time for entire bottle.)

4. After pouring BlueDevil slowly, replace radiator cap. Let vehicle idle with CAP ON for 50 minutes maintaining normal operating temperature.

5. Top off radiator with antifreeze and water. BlueDevil can remain in the system.
