Corrosion Prevention
Within a cooling system, there is a range of metallic components, To be effective, a coolant must possess anti corrosion qualities to protect each type of metal. Genuine Toyota Long Life Coolpant has been evaluated using a range of metals, incuding aluminum alloy, cast iron, steel, brass, solder and bronze. it has demonstrated optimal corrosion protection and does not damage non-metallic parts (rubber, resin etc.). Non-genuine long life coolants were not created specifically for Toyota cehicles any may, therefore, cause corrosion.
