Corrosion Inhibitor Prevents Oxidisation

Vehicles that operate in temperate climates benefit from using an engine protector coolant. A water-based coolant is more effective for these environments. It prevents rusting throughout your car’s cooling system. Natrad supply Australian designed (and made) radiator corrosion inhibitors for a range of vehicles.

Natrad’s radiator corrosion inhibitor range covers new European and Japanese vehicles, performance vehicles, and passenger vehicles. We supply coolant for light trucks, vans, 4WDs, trucks, buses, motorcycles, and quad bikes. Radiator corrosion inhibitors are also available for heavy-duty industrial, mining, and agricultural applications.

FAQs

  • What is a radiator corrosion inhibitor?

    Radiator corrosion inhibitor is a type of coolant which prevents cavitation, scaling, and oxidisation in vehicles which don’t need an antifreeze anti-boil coolant.

    It provides maximum protection against corrosion while providing highly effective heat transfer to reduce the temperature of the engine during operation.

  • Does the cooling system need to be flushed?

    The cooling system needs to be flushed when the coolant is replaced to remove the light scale, sediment, and depleted inhibitors in the cooling system. Flushing needs to be done in order to prevent leaks, corrosion, and overheating.

    Flushing the system also prevents contamination from the previous coolant. This is particularly important when changing to an organic acid technology coolant to achieve the maximum benefit.

  • Do I need to use an antifreeze anti-boil coolant or is a corrosion inhibitor better?

    If your vehicle will be exposed to freezing temperatures, you must use an antifreeze anti-boil coolant. In non-freezing environments, a water-based corrosion inhibitor will give better cooling efficiency. Ask a Natrad specialist or check your vehicle handbook if you are unsure.

  • Can I buy coolant in bulk?

    You can buy coolant in large, cost-effective sizes, from 1L up to 1000L. Ask your local Natrad about buying the corrosion inhibitor or antifreeze anti-boil coolant you need in bulk.

  • Can you flush and replace the coolant for me?

    Your Natrad technician can test your existing coolant to see if it needs to be replaced. If the coolant needs to be replaced, the technician will flush the cooling system before replacing the coolant.
