Red Radiator Corrosion Inhibitor is a Type “B”, coolant inhibitor concentrate that protects against corrosion, cavitation, scaling and oxidisation in vehicles that do not require a Type “A” Anti-Freeze Anti-Boil coolant. 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.


Red 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.

Red 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.

  • Red Radiator Corrosion Inhibitor should be used at a ratio of 50ml per litre of water.
  • Penrite De-mineralised Water is recommended for dilution.
  • 1 litre makes up to 20 litres of coolant.

HINT: For best results flush cooling system with Radiator Flush prior to filling with Red Radiator Corrosion Inhibitor
