TotalEnergies Coolelf Auto Supra 2F -26°C – High-Performance Long-Life Coolant
TotalEnergies Coolelf Auto Supra 2F -26°C is a ready-to-use coolant based on monoethylene glycol (MEG) with organic acid technology (OAT) corrosion inhibitors. The formulation is free from 2-EHA, nitrites, and borates, offering extended drain intervals with outstanding corrosion and frost protection. It is the successor to Coolelf Auto Supra -26°C.
Product Advantages
• Excellent protection against corrosion, erosion, and cavitation – even at high temperatures
• Reliable frost protection down to –26 °C and increased boiling point to approx. 106 °C (ASTM D1120)
• Deposit prevention through advanced OAT inhibitors
• Optimal heat transfer and thermal stability
• Compatible with common elastomers, paints, and hard water (max. 40 °F)
• High reserve alkalinity to neutralize acids formed during combustion
• Mixable with the previous Coolelf Auto Supra -26°C (full change recommended)
Typical Applications
• Cooling systems of combustion engines in passenger cars, trucks, buses, construction, and agricultural machinery
• Indirect battery cooling in EVs (when no special OEM conductivity requirements apply)
• Suitable for engines made of cast iron or aluminum, and radiators made of aluminum or copper alloys
