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.

Protection
from Overheating
A reducation in the boiling point of a long
life coolant can increse evaporation leading
to a decrease in coolant volume and eventually,
overheating. Genuine Toyota Long Life Coolant
is based on ethylene glycol and surpases
Toyota's strict quality standartds. in addition,
mineral deposits are less likely to form
in Genuine Toyota Long Life Coolant.

Protection from Freezing
When the air temperature drops below the
freezing point, any and all cooants may
freeze. As a result, expansion can cause
cracks in the engine cylinder block. Genuine
Toyota Long Life Coolant maintains an optimal
freezing point, which passes Toyota's strick
standards and prevents freezing.
