Three-in-one protection

In June 2023, Product Profile3 MinutesBy NZ Trucking magazineJuly 20, 2023

Cooling system problems can cause significant unanticipated downtime. Once problems from overheating start, they spread throughout the engine. And because today’s lower-emission engines can run extremely hot, it’s more important than ever to catch cooling problems before they lead to major engine overhauls.

There are myriad coolant options available for fleets. The ALL FLEET HDD Coolant provides exceptional summer cooling and excellent freezing protection during winter.

ALL FLEET HDD Coolant is a fully formulated, high-quality, long-life, heavy-duty diesel engine coolant based on hybrid technology, which offers conventional technology coupled with Organic Acid Technology.

The product is a three-in-one – offering anti-freeze (-37°C), anti-rust and anti-boil. It has a service life of six years, 12,000 hours or 1,000,000km – whichever comes first.

Hybrid technology coolants have the advantage of being more robust than conventional and organic acid-technology engine coolants.

The low silicate, phosphate and amine-free product is recommended for use in automotive, light-duty and heavy-duty diesel applications, namely on road and offroad trucks, as well as farm and marine equipment.

ALL FLEET HDD provides excellent high-temperature aluminium protection and does not require an initial charge of supplemental coolant additives (SCAs) upon initial fill in heavy-duty diesel applications, as the product is specially formulated to protect heavy-duty diesel wet sleeve liners.

ALL FLEET HDD meets the requirements for Caterpillar, Cummins, Mack, Detroit Diesel, DaimlerChrysler, Ford, MAN, Mercedes-Benz, MTU, New Holland, Peterbilt, Land Rover, Kenworth, Scania, Perkins, Freightliner and Volvo. It is available in concentrate and pre-mixed formulas.

The ALL FLEET HDD Coolant and Auto Star Fleet & Truck Wash is available at NAPA Auto Parts. Visit or call 088 800 073 to find your nearest branch.
