New coolant
Advanced formula with phosphates
Komatsu Supercoolant helps provide better protection against corrosion and a longer life to reduce downtime and costs
Your equipment can face a range of temperature extremes. Without proper protection against high heat and extreme cold, corrosion could occur in the engine, which leads to performance issues. The new Komatsu Supercoolant delivers a formula designed to better protect components against the elements and premature failure.
Komatsu Supercoolant uses advanced POAT (phosphated organic acid technology) with corrosion inhibitors. The new formula has been certified for use in Cummins heavy-duty diesel engines and meets CES 14603 standards. This means it can be used in all Komatsu equipment and other all-makes equipment with Cummins engines.
“The new Komatsu-specific formula adds phosphates that provide extra protection for components against corrosion,” explained Tony Laskero, Komatsu’s Senior Manager of Aftermarket. “That protection helps ensure long life and that components don’t prematurely wear.”

In addition to better protection, the new Komatsu Supercoolant formula has a longer replacement interval — up to 12,000 hours with regular KOWA (Komatsu Oil and Wear Analysis) sampling and adding an extender additive after 6,000 hours.
“KOWA should be performed at every maintenance interval as it’s similar to a ‘blood test’ that can identify issues that need to be addressed before they become catastrophic,” Laskero said. “With this new Komatsu Supercoolant, at 6,000 hours, you should perform a KOWA, and if everything is in good working order, you can add the extender to prolong life. An additional KOWA should be performed at 9,000 hours. At 12,000 hours, it’s time to flush the cooling system and add new Supercoolant.”

When switching from the previous Komatsu Supercoolant formula, a cooling system flush is not needed. However, it should not be mixed with other coolant brands.
“If you are using a different brand of coolant currently, it is advised that you perform a coolant system flush before using Supercoolant for the first time,” stated Laskero. “Once you have Komatsu Supercoolant in your machinery, you get extended interval replacement, which can help reduce downtime and maintenance costs. A bonus is you can use it in non-Komatsu equipment with Cummins engines.”
Komatsu Supercoolant is available in 1-gallon jugs, 5-gallon pails, 55-gallon drums and 320-gallon totes through your Komatsu distributor and on My Komatsu. Consult your machine’s operator and maintenance manual (OMM) or distributor representative for the proper fluid level.
