Bardahl Radiator Fast Flush uses wetting agents and solvents to clean out the insulating deposits caused by anti-freeze. Its wetting ingredients break down the molecular tensions that hold the jells together. The solvents penetrate to all areas where the deposits collect, breaking up and dissolving the unwanted insulation so it can be washed out of the system.
Bardahl Fast Flush can be used both before and after anti-freeze is added. It should be used before fresh coolant is put in. Use this radiator additive whenever minor overheating problems occur.
Do not add more than prescribed, this may have an adverse effect.
