HIGHTEC ANTIFREEZE COOLANT AN 12 EVO is a premium long-service coolant concentrate based on monoethylene glycol. Its advanced OAT-style additive package gives outstanding corrosion and frost protection while keeping cooling channels clean over extended drain intervals. The nitrite-free, amine-free and phosphate-free chemistry is gentle on seals and modern engine metals.

Purpose and specifications

Developed for cooling systems of current passenger cars and commercial vehicles with aluminium and cast iron engines. It meets ASTM D3306, ASTM D6210, BS 6580:2010 and SAE J1034, and carries broad approvals including VW TL L(G12Evo), VW TL J(G13), MB 325.3, MAN 324 Si-OAT, Cummins CES 14603 and Toyota Long Life Coolant 1WW.

• 1.5L container of concentrate to mix with water for a full cooling system
• When mixed 1:1 it protects to approximately -37 C for confident cold starts
• Long-life corrosion and cavitation protection that prevents scale and deposits
• Covers G12Evo, G12++ and G13 systems for fleet rationalisation

When to use / change?

Choose it when refilling or replacing the coolant in vehicles specifying a G12Evo, G12++ or G13 long-life fluid. As a long-service coolant it is generally renewed every 3 to 5 years or per the manufacturer interval. Mixed with demineralised water it protects across a range of about -37 C to +120 C. Sealed and stored cool and dry, shelf life is approximately 5 years.

Frequently asked questions

How should I dilute the concentrate?
A 1:1 mix with clean demineralised water gives frost protection to roughly -37 C; adjust the ratio for colder climates.

Can it replace G12++ and G13 coolants?
Yes. It is approved as a rationalisation coolant covering G12Evo, G12++ and G13 specifications.

Is it compatible with aluminium engines?
Yes. The phosphate-free, silicate-managed OAT formula protects both aluminium and cast iron engines.

Suitable for: Volkswagen Golf, Audi A6, BMW 5 Series, Mercedes-Benz E-Class, Ford Mondeo, Toyota Corolla. Always verify the exact approval against your vehicle's owner manual before use.
