ANTIFREEZE COOLANT YELLOW VCS CONCENTRATE LONGLIFE MEG

Antifreeze Coolant Yellow VCS (Variable Composition System) Concentrate Long-life MEG (Mono ethylene Glycol) is a premium, high-performance coolant formulated for a diverse range of vehicles and cooling systems. This vibrant yellow concentrate must be diluted—typically at 50/50 with deionized or distilled water—to ensure protection from freezing down to approximately –36 °C and overheating up to around 170 °C under pressure.

The VCS technology features a variable inhibitor package tailored to offer broad compatibility across multiple OEM specifications. This long-life formula employs Organic Acid Technology (OAT) enhanced with select inorganic components to deliver extended protection against corrosion, scale, and cavitation. It shields critical engine metals—such as aluminum, copper, cast iron, and steel—from degradation while maintaining a clean cooling system free of sludge and deposits.

Designed for long drain intervals, this coolant provides dependable protection for up to five years or around 250,000 km, making it suitable for modern passenger cars, light commercial vehicles, and heavy-duty equipment. It is backward-compatible with many existing yellow, orange, or red coolants of similar chemistry, though complete system flushing is recommended when switching types.

In summary, Antifreeze Coolant Yellow VCS Concentrate Long-life MEG offers versatile, long-lasting freeze, boil-over, and corrosion protection with wide OEM compatibility—ideal for mixed-fleet applications requiring durable thermal management.
