A high-performance low toxicity engine coolant concentrate (antifreeze) based on propylene glycol, suitable for both petrol and diesel engines. The product is free from nitrites, amines, phosphates, borates, and silicates and contains no other mineral additives. KOOL-GUARD MPG OAT is also well suited to non-automotive applications such as solar installations and industrial heat-transfer systems.

Product Code: 01840

Much lower toxicity than ethylene glycol-based coolants
When used at the recommended concentrations, it provides long-lasting corrosion protection for a minimum of 5 years, or 250,000KM (1,000,000KM in commercial vehicles)
Thermal characteristics permit effective engine cooling without boiling
Elimination of deposit problems caused by the use of hard water
Elimination of abrasives solids, which gives better protection of the joints of the water pump. Improved anti-corrosion protection of all metals and alloys used in the cooling system of modern vehicles, especially aluminium.
Protection against frost, depending upon the concentration chosen.
Excellent antifoaming characteristics. Free from nitrites, amines, phosphates, borates and silicates
Compatible with most other propylene glycol and ethylene glycol-based coolants, but for optimum performance and durability, we recommend that before using KOOL-GUARD MPG OAT in systems previously filled with traditional coolant that the cooling system is drained and flushed with clean water before filling with KOOL-GUARD MPG OAT diluted following the vehicle manufacturers instructions. We recommend a 50% dilution with good-quality water.
