Exol Lubricants has broadened its coolant offering with the addition of Opticool Antifreeze Orange (D052), a heavyduty engine coolant designed to meet the evolving requirements of modern engines and fleets.
Developed without nitrites, amines, phosphates, borax or silicates, the formulation reflects a growing shift towards longer-life, environmentally considerate coolants that maintain system protection without compromising performance.
The product’s inhibitor package provides corrosion resistance across the full range of metals and alloys typically found in today’s cooling systems – particularly aluminium – while a built-in neutralisation component helps counteract the effects of brazing flux used in the production of aluminium heat exchangers. Exol reported this combination supports longer component life and reduced maintenance intervals.
Exol also claimed the coolant offers extended service life, high thermal stability and enhanced water pump protection, aided by the removal of abrasive solids. It also provides reliable frost protection – depending on concentration – and antifoaming properties, while remaining compatible with different water qualities – although deionised water is recommended for best results.
“Reduced maintenance intervals”
Opticool Antifreeze Orange is suitable for a wide range of heavy-duty and OEM applications, including Caterpillar, John Deere, Jaguar Land Rover, Peugeot, Citroën, Volvo, Perkins and Massey Ferguson.
A 50:50 coolant-to-water mix is recommended for general use, with higher concentrations suited to colder climates.
Exol Lubricants Product Development Manager, Simon Matthews, said: “The addition of Opticool Antifreeze Orange strengthens our coolant portfolio and provides customers with a versatile, highquality solution suitable for a wide range of modern heavy-duty applications. Its formulation delivers exceptional performance and long-term protection, helping fleets and workshops reduce maintenance intervals and optimise engine reliability.”
As modern engines continue to evolve and service intervals lengthen, coolants like Opticool Antifreeze Orange underline the importance of preventative maintenance – helping both you and your workshop customers stay aligned with the demands of newer vehicle technologies.
