As commercial vehicle engines – especially those running on natural gas – run hotter than before, engine cooling systems need to work harder. Materials that make up cooling systems vary from vehicle to vehicle, so it is vital to make sure that you use the right coolant for each application.
Our coolant range offers excellent protection in commercial vehicle engines and features extended-life products that maintain performance even under extreme conditions.
