A high-performance ready-to-use ethylene glycol-based engine coolant which employs Organic Acid Inhibitor Technology.

Product Code: 08830

Free from nitrites, amines, phosphates, borates and silicates
KOOL-GUARD XL -10 provides long lasting corrosion protection for a minimum of 5 years, or 250,000KM (500,000KM in commercial vehicles).

It is suitable for use in all vehicles unlike traditional coolants which employ inorganic inhibitors, KOOL-GUARD XL -10 has excellent hard water stability and very low inhibitor depletion rates.

Compatible with most other ethylene glycol-based coolants, but for optimum performance and durability, we recommend that before using KOOL-GUARD XL -10 in systems previously filled with traditional coolant, the cooling system is drained and flushed with clean water before filling with KOOL-GUARD XL -10 diluted following the vehicle manufacturers instructions.
