Free from nitrites, amines, phosphates, borates and silicates
When used at the recommended concentrations, it 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 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 in systems previously filled with traditional coolant the cooling system is drained and flushed with clean water before filling with KOOL-GUARD XL diluted following the vehicle manufacturers instructions. We recommend a 50% dilution with good-quality water.
