Radtech RXB500 is a Blue advanced technology hybrid organic inhibitor, ethylene glycol based, anti-freeze / anti-boil coolant concentrate with thermal conductivity additives and heat dissipation polymers (water wetting technology) that protects against corrosion in cooling systems.
Radtech RXB500 is ideal for multi-fleet applications as it provides protection for all common metals found in cooling systems; copper, aluminium, cast iron, lead, brass, steel etc. Radtech RXB500 is silicate free. Radtech RXB500 is ideal for both petrol & diesel applications.
The low soluble solid content means that seals, hoses and gaskets will last longer.
Utilising state-of-the-art water wetting technology, Radtech RXB500 is ideal for extreme conditions. Reduction in engine operating temperatures and coolant loss are additional benefits unique to Radtech RXB500.

  • Utilising latest generation OAT (Organic Acid Technology) inhibitors – provides engine protection for up to 5 years or 250,000 km. 
  • Additionally a high quality anti-foaming agent helps to eliminate cavitation corrosion and extend water pump life.
  • Can be diluted down to 33%, but is recommended at 50% dilution in-line with vehicle manufacturer’s specifications, or in sub-zero temperatures.
  • Provides anti-freeze protection down to -37°c at a 50% dilution.
  • Provides anti-boil protection up to 132°c at a 50% dilution.
  • Universal use – meets or exceeds standard industry requirements for automotive applications.

Radtech RXB500 can typically be used in Toyota passenger vehicles, Holden V8’s etc or any other vehicles that require a red full glycol anti-freeze / coolant.
