Long Life Coolant Blue is an ethylene glycol based anti-freeze/coolant concentrate incorporating an advanced Organic Acid Technology (OATS) formula with virtually non-depleting organic acid corrosion inhibitors. The product is dyed a distinctive blue colour for ease of identification.

It is silicate free for improved pump life and contains no environmentally harmful nitrates, borates, phosphates, amines or nitrites.

Long Life Coolant Blue 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.

Long Life Coolant Blue satisfies or exceeds many major standards and is recommended for major European, Japanese and US car and heavy-duty diesel engines.

Long Life Coolant Blue can be added directly to the cooling system as a top-up adjustment of the freeze point of the cooling water.


Long Life Coolant Blue 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 Long Life Coolant Blue 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, Long Life Coolant Blue 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.

Long Life Coolant Blue anti-freeze/coolant must not be used neat to the engine cooling system but diluted up to minimum 33% or maximum 67% with good quality water. The dosage depends on the level of frost protection required and/or the manufacturer’s recommendation. For optimum year round protection against freezing, boiling and corrosion, 50% Long Life Coolant Blue coolant solution is recommended.

While Long Life Coolant Blue is compatible with hard water, the use of soft or deionised water is preferable to minimize scale deposits.

Do not mix Long Life Coolant Blue coolant with other coolant products as the extended life benefits will be reduced. If mixed with more than 15% of conventional coolant, treat the cooling system as if it contains the conventional coolant or drain and flush the system and refill with Long Life Coolant Blue.


Always start off with a clean cooling system by using a radiator flush or similar commercial cleaner at the change-over (especially if previously using conventional coolants). After draining the cleaner, flush thoroughly with clean water.

Inspect the cooling system. Make necessary repairs and tighten all hose connections.

The coolant should be changed out at overhaul or 5 years. Always dispose of the used coolant in accordance with local, state and federal guidelines.

Because Long Life Coolant Blue is silicate free, the product can be stored for up to 8 years with no problem.


Advantages of using Long Life Coolant Blue include:

  • Suitable for use in a wide range of OEM diesel, gasoline, and natural gas engines, reducing the need for multiple coolant types in inventory.
  • Offers a significantly extended service life, up to three times longer than conventional coolants.
  • Drastically cuts engine coolant expenses, potentially saving up to 60% compared to traditional alternatives.
  • Provides impressive service life: up to 1,000,000 km for truck engines and up to 12,000 hours or 6 years (whichever comes first) for machinery and commercial engines, with the option to extend it through a single coolant extender addition at the initial service life’s end.
  • For automotive engines, it’s recommended to drain at 250,000 km or 5 years, whichever comes first.
  • Free from silicates, as well as environmentally harmful borates, phosphates, amines, or nitrates.
  • Virtually eliminates hard water deposits and scale formation in the cooling system, reducing maintenance requirements.
  • Low total dissolved solids content enhances water pump seal durability and prevents gel formation.
  • Ensures exceptional heat transfer efficiency and superior protection for aluminum components under high operating temperatures.
  • • The combination of organic carboxylate inhibitors offers outstanding defense against pitting, cavitation, corrosion, and erosion of cast iron cylinder liners and engine blocks
