Coolant / Antifreeze OAT G12 EL 50 Yellow

Greyhound Coolant / Antifreeze OAT G12 EL 50 Yellow

Greyhound Coolant / Antifreeze OAT G12 EL 50 Yellow is our 50/50 ready-to-use extended life coolant on silicate-free Organic Acid Technology (OAT G12), in yellow — the colour common to universal coolants and colour-coded mixed fleets. Specifically, it keeps fleet identification consistent while upgrading every cooling system to G12 extended life protection.

Because corrosion and cavitation damage modern aluminium cooling systems, extended-life organic inhibitors act directly at corrosion sites. Moreover, the formula is free of silicates, nitrites, amines, phosphates and borates, so radiators stay deposit-free and heat transfer stays efficient for the full extended interval.

Yellow OAT G12 Coolant for Mixed Fleets

For example, a fleet can standardise every yellow-coded vehicle on one modern coolant. In addition, it suits petrol and diesel engines alike. As a result, top-ups stay consistent across the yard. Therefore, colour-coding and chemistry finally agree.

Key Features:

• Yellow-dyed OAT G12 extended life coolant for colour-coded fleets
• Ready to use — factory pre-mixed 50/50 with deionised water
• Freeze protection to –37°C; boil-over protection above 108°C (pressurised)
• Extended drain intervals vs G11 antifreeze
• Silicate-free — no deposits or gels in the radiator
• Protects aluminium, cast iron, steel, brass and water pump seals
