TotalEnergies Glacelf Auto Supra 2F – High-Performance Coolant Concentrate
Glacelf Auto Supra 2F is a coolant concentrate based on monoethylene glycol (MEG) with organic inhibitors (OAT). It is free of 2-EHA, nitrite and borate and is the successor to Glacelf Auto Supra. The product ensures long-lasting corrosion and frost protection and is suitable for modern cooling systems in passenger cars, trucks, buses, construction and agricultural machinery. It can also be used in electric vehicles for indirect battery cooling, provided no specific OEM requirements on electrical conductivity apply.
Product Advantages
• Excellent protection against corrosion, erosion and cavitation, even at high temperatures
• Freezing point depression and boiling point elevation for maximum safety
• Prevents deposit formation thanks to special OAT inhibitors
• Permanent, optimal heat transfer
• Compatible with common elastomers and paints
• High reserve alkalinity for neutralizing acidic combustion residues
• Suitable for hard water (up to 40 °F)
• Mixable with Glacelf Auto Supra, though a complete change is recommended for full performance
Typical Applications
• Cooling systems in cars, trucks, buses, construction and agricultural machinery
• Engines with cast iron or aluminum components
• Radiators made of aluminum or copper alloys
