Description

Premium Long-Life Protection

Würth Concentrated Red Antifreeze and Summer Coolant is a high-performance ethylene glycol-based coolant formulated with advanced organic acid technology (OAT) inhibitors. It provides outstanding, long-lasting protection against frost, overheating, and corrosion, ensuring reliable engine performance in all climatic zones.

Exceptional Performance Range

When diluted with clean water, the coolant provides protection against freezing down to -70°C, making it suitable for extreme cold conditions. In hot climates, it safeguards against overheating and scale formation, ensuring a stable operating temperature year-round.

OEM Approved and Compatible

This antifreeze is approved to meet or exceed the requirements of leading vehicle manufacturers and international standards, making it a versatile choice for modern petrol and diesel vehicles. Its silicate- and phosphate-free formula ensures compatibility with modern lightweight alloys and aluminium engine components, preventing pitting and corrosion.

Long Service Life

With a service life of five years or 100,000 miles, this coolant reduces the need for frequent changes, lowering maintenance costs while providing continuous system protection.

More Information

Application Instructions

  1. Drain and flush the cooling system is necessary.
  2. Dilute the concentrate with clean water only. Do not exceed a concentration above 70%. Dilution ratios determine frost protection, (e.g. 50:50 mix protects down to approx. -35°C).
  3. Add the prepared mixture directly into the cooling system.
  4. Run the engine until warm and the thermostat has opened, ensuring circulation.
  5. Check coolant level and top up if required.

Usage Notes

  • Suitable for both petrol and diesel engines.
  • Do not mix with non-OAT coolants - if unsure, flush the system before filling.
  • Store at ambient temperatures, avoiding prolonged exposure above 40°C.
