HIGHTEC ANTIFREEZE COOLANT AN 12 EVO READY-MIX is a premium long-life coolant based on monoethylene glycol, supplied pre-mixed for instant frost protection to -40 C. Its modern OAT-style additive technology delivers high corrosion and frost protection while keeping cooling channels clean over long service intervals. The nitrite-free, amine-free and phosphate-free chemistry is gentle on seals and engine metals.

Formulated for the cooling systems of modern passenger cars and commercial vehicles with aluminium engines and cast iron engines. It meets ASTM D3306, ASTM D6210, BS 6580:2010 and SAE J1034, and carries 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.

• 5L container for a complete cooling system fill or top-up
• Ready-mixed for immediate frost protection to approximately -40 C, no dilution needed
• Long-life corrosion and cavitation protection that prevents scale and deposits
• Covers G12Evo, G12++ and G13 systems, ideal as a single rationalisation fluid

When to use / change?

Choose it when refilling or replacing coolant in vehicles specifying a G12Evo, G12++ or G13 long-life fluid. As a long-service coolant it is normally renewed every 3 to 5 years or per the manufacturer interval. It performs across an operating range of about -40 C to +120 C. Stored sealed in a cool, dry place, shelf life is approximately 5 years.

Frequently asked questions

Does it need diluting before use?
No. This is a ready-mix that should be used as delivered, already protecting to roughly -40 C.

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

Is it safe for aluminium engines?
Yes. The phosphate-free OAT formula reliably protects both aluminium and cast iron engines.
