Neste Pro Coolant XLC-II Ready is a ready-to-use new generation, ethylene glycol-based long-life coolant which is developed by the organic acid (OAT) technology. It is a very versatile and multifunctional coolant that can be used in many heavy duty equipment cooling systems.
YEAR ROUND FREEZING AND CORROSION PROTECTION
Neste Pro Coolant XLC-II Ready is made from the highest quality ethylene glycol and cutting-edge additive solution which provides reliable and safe cooling system operation even at very cold outdoor temperatures (please check coolant / water mixing concentration rates). It keeps the cooling system free from corrosion and maintains it for optimal performance.
LONG DRAIN INTERVALS
It is backboned by OAT (organic acid technology) that provides unique oxidation stability and extends coolant's working life. Extended drain intervals help to reduce the amount of waste and therefore maintenance expenses.
EXCELLENT PERFORMANCE
Neste Pro Coolant XLC-II Ready shows excellent technical features, such as: superior oxidation and pH stability at high temperatures, compatibility with hard water, outstanding heat transfer features and superior flux compensation. It has a very low degradation rate and keeps the cooling system free from deposits.
ENVIRONMENTAL FRIENDLIER
It is manufactured to reduce environmental impact: free from 2-EHA, nitrite and borate and compliant with EU CO2 emission performance standards

Applications
Neste Pro Coolant XLC-II Ready 50 % is a versatile ready-to-used coolant suitable for combustion engines and Battery Electric Vehicles (BEV) in both automotive and heavy-duty applications, provided there are no specific requirements regarding electrical conductivity. This coolant is specifically developed for heavy-duty vehicle cooling systems but is also applicable to a wide range of light-duty vehicles and equipment from manufacturers such as Alstom, Behr, Chrysler, Evobus, Freightliner, GWM, Hitachi, Isuzu, Jeep, John Deere Power Systems, Kobelco, Kubota, Leyland Trucks, Maserati, Perkins, Santana Motors, Tata, Thermo King, UD Trucks, Vestas, Voith, and Yanmar. The performance and durability of the coolant are influenced by water quality. While distilled or deionized water is ideal, the minimum requirement is clean "tap water" with a maximum hardness of 10 °d. It is recommended to use at least 30 vol.% of the antifreeze in the final coolant solution to achieve a freeze point of -16°C. In Northern Europe, common mixtures are 50/50, providing protection down to -37°C. Concentrations exceeding 70 vol.% are not advised as they do not offer additional frost protection. Neste Pro Coolant XLC-II is fully compatible and mixable with Neste Pro Coolant XLC and can be used in all applications where Neste Pro Coolant XLC is suitable.
