Coolants & Brake Fluids

Product Benefits

• Advantages of using DD 50 Yellow Coolant include:

  1. Can be used in most OEM diesel, petrol and natural gas engines allowing one coolant to be inventoried. The product lasts up to 3 times as long as conventional coolants.
  2. Service life of up to 1,000,000 kms for truck engines, and up to 12,000 hours or 6 years (whichever comes first) for machine/commercial engines (when topped up with a once only coolant extender at the end of its initial service life).
  3. Reduces engine coolant cost by up to 60% over conventional coolants.
  4. For automotive engines, drain at 250,000 km or 5 years, whichever comes first.
  5. Contains no silicates or environmentally harmful borates, phosphates, amines or nitrates.
  6. Excellent heat transfer and superior aluminium protection at high operating temperatures.
  7. The combination of organic carboxylate inhibitors offers excellent protection against cast iron cylinder liner and block pitting and cavitation corrosion/erosion.
  8. Hard water deposits and scale from silicate drop out in the cooling system are practically eliminated.
  9. The low level of total dissolved solids improves water pump seal life and prevents gel formation.

  DD 50 Yellow Coolant is recommended for heavy-duty engines manufactured by Caterpillar, Cummins, Detroit Diesel, Komatsu, Mack-RVI, Mercedes Benz, MTU, Scania and other OEM’s.
