DEI Radiator Relief 16 Oz. Performance Additive

A preventive treatment to avoid overheating, electrolytic (electrolysis) and chemical corrosion, Radiator Relief (40200) is compatible with all coolant additives and anti-freeze mixtures. It is also safe with all types of radiators, including cast iron, copper, brass, and aluminum. Best of all, it can reduce coolant temperatures up to 30 degrees.
