Radiator Corrosion Inhibitor is a green coloured, hybrid-organic, Type "B", corrosion inhibitor concentrate that protects against cavitation, scaling and oxidisation in vehicles that do not require an Anti-Freeze Anti-Boil cooIant. It is an effective engine coolant that uses a Hybrid Organic Acid Technology (HOAT) inhibitor to provide maximum protection against corrosion whilst providing superior heat transfer to reduce engine operating temperature.

Radiator Corrosion Inhibitor Replaces RADIATOR INHIBITOR


Radiator Corrosion Inhibitor is suitable for use in a wide range of vehicles including passenger cars, light commercials vehicles, motorcycles, trucks, buses, stationary engines and other equipment.

Radiator Corrosion Inhibitor when mixed with water will help provide improved heat transfer abilities over straight water by reducing cavitation and eliminating hot spots inside the engine. This can help lower the running temperature of the engine, preventing damage from overheating whilst the inhibitor pack will prevent rust, corrosion, scaling and oxidation if maintained at the correct dosage.

  • Radiator Corrosion Inhibitor should be used at a ratio of 50ml per litre of water.
  • Penrite recommend mixing with Penrite De-Mineralised Water
  • 1 litre makes up to 20 litres of coolant.
