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.


In Stock


DD 50 Yellow Coolant is an ethylene glycol based antifreeze/coolant premix incorporating an advanced formula technology with virtually non-depleting organic acid corrosion inhibitors. The product is dyed a distinctive yellow colour for ready identification. It is silicate free for improved pump life and contains no environmentally harmful nitrates, borates, phosphates, amines or nitrites.

DD 50 Yellow Coolant is compatible with conventional coolants and can be used for top-up of conventional coolants. If the product is to be mixed with some heavy duty diesel coolants, the user must continue to add SCA’s (Supplementary Coolant Additives) for heavy-duty service until the next coolant change-out. DD 50 Yellow Coolant satisfies or exceeds many major standards and is recommended for major European, Japanese and US car and heavy-duty diesel engines. DD 50 Yellow Coolant can be added directly to the cooling system as a top-up adjustment of the freeze point of the cooling water.

DD 50 Yellow Coolant is recommended for use in aluminium alloy petrol powered automotive engines, and in heavy duty diesel and natural gas mobile and stationary engines.

Provided the correct dosage of DD 50 Yellow Coolant is maintained, flush and change the passenger car/light duty commercial vehicle cooling system contents every 5 years or 250,000 km. For heavy-duty diesel engines, DD 50 Yellow Coolant more than doubles the life of conventional coolants to 500,000 km / 6,000 hours / 5 years; at the same time providing excellent protection against cylinder liner cavitation corrosion/erosion.
