YEFE Dione BS Concentrated is a high performance engine coolant and antifreeze concentrate that exceeds key British Standard and AFNOR requirements for year-round protection. Formulated for use in both petrol and diesel engines, it provides three-way protection against freezing, overheating and corrosion, making it suitable for mixed fleets and a broad range of passenger cars and light commercial vehicles. The monoethylene glycol base is designed to be truly universal in application, delivering a high degree of corrosion protection for cooling systems constructed from aluminium as well as ferrous materials. YEFE Dione BS Concentrated has been engineered to maintain effective heat transfer and system cleanliness, helping prevent scale and deposit formation that can reduce cooling efficiency. The product does not contain nitrites, amines or phosphates, which supports stable operation in modern radiators and coolant passages while minimising the risk of harmful residues. By using the correct dilution ratio and demi water—such as distilled or deionised water—users can tailor freeze protection and corrosion performance to climate and manufacturer recommendations. To ensure proper performance, YEFE Dione BS Concentrated should be mixed at a minimum concentration of 33% (1:2) volume in the coolant solution. Most car manufacturers advise a balanced concentration of 50% (1:1) volume for optimal results, offering both effective corrosion protection and enhanced overall cooling system performance. In extremely cold climates, concentration can be increased to 67% (2:1) volume to prevent freezing and improve coolant reliability. Tap water should be avoided to maintain system cleanliness and coolant effectiveness.
