Heavy duty coolants

Natrad's coolants are engineered to provide superior thermal protection and durability for industrial and commercial vehicles, including heavy duty diesel vehicles.

Boost engine life with our heavy duty coolants

Coolant, also known as antifreeze or radiator coolant, protects engines from overheating and is crucial for optimal engine performance. Coolant provides corrosion protection for the  parts it comes into contact with, which protects against damage to the water pump, radiator, heater, thermostat and more..

By effectively managing heat and preventing overheating, these coolants help to reduce engine wear and tear, helping to extend the lifespan of your vehicle’s critical components, including diesel passenger cars.

In addition to superior temperature control, Natrad’s coolants feature advanced corrosion protection, safeguarding your engine’s internal parts from rust and scale buildup. This not only enhances the efficiency of your cooling system but also reduces maintenance costs over time, allowing you to focus on what matters most—keeping your vehicle on the road and performing at its best.

FAQs


  • Why is engine coolant important?

    Coolant performs three main functions to protect your car engine:

    1. Coolant transfers heat from the engine and releases it through the radiator, keeping the engine at a safe operating temperature.
    2. Coolant generally has a higher boiling point and a lower freezing point than plain water.
      -If the water in the engine boils, it turns into a gas, which cannot transfer heat effectively.
      -If the liquid in the cooling system were to freeze, it would expand, potentially damaging parts of the cooling system and the engine.
    3. The same coolant contains corrosion inhibitors that protect the metallic and non-metallic (rubber hoses, seals, plastic tanks, etc.) parts of the engine cooling system.
  • Why use coolant and not just water?

    There are two key advantages of using engine coolant rather than just water.

    First, coolant has a higher boiling point than water. This means that when parts of the engine heat to over 100°C, the coolant liquid won’t boil.

    The second key reason to use coolant is that coolant contains corrosion inhibitors. This protects the components of your engine and cooling system from corrosion. It’s much cheaper to buy coolant and check it regularly than it is to replace major parts of your car engine and cooling system.

  • What are the different types of car coolant?

    There are 2 main different types of car coolant available.

    • Anti-freeze/anti-boil (AFAB) Australian Standard AS2108-2004 “Type A” Coolant. This comes in various special formulations for particular uses:
      • Organic Acid Technology (OAT) premium AFAB coolant for general use
      • Hybrid Additive Technology (HAT) AFAB coolant for general use
      • Phosphate-based AFAB coolant (formulated for Japanese & Korean car makes)
      • Silicate-based AFAB coolant (formulated for European car makes)
    • Corrosion inhibitor (CRIN) Australian Standard AS2108-2004 “Type B” Coolant. This comes in various special formulations for particular uses as well.
      • Regular formulation
      • Organic Acid Technology (OAT) premium corrosion inhibitor for general use
