Recommended engine coolant
• When adding coolant, use only dis-
tilled (deionized) water for your ve-
hicle and never mix hard water in
the coolant filled at the factory. An
incorrect coolant mixture can result
in serious malfunction or engine
damage.
• The engine in your vehicle has alu-
minum engine parts and must be
protected by an phosphate based
ethylene-glycol coolant to prevent
corrosion and freezing.
• DO NOT USE alcohol or methanol
coolant or mix them with the speci-
fied coolant.
• Do not use a solution that contains
more than 60% antifreeze or less
than 35% antifreeze, which would
reduce the effectiveness of the so-
lution.
For mixture percentage, refer to the
following table.

Information
i
If in doubt about the mix ratio, a 50%
water and 50% antifreeze mix is the
easiest to mix together as it will be the
same quantity of each. It is suitable to
use for most temperature ranges of
-35°C (-31°F) and higher.

WARNING
Never remove the radia-
tor cap or the drain plug
while the engine and ra-
diator are hot. Hot cool-
ant and steam may blow
out under pressure, causing seri-
ous injury.
Turn the engine off and wait until
the engine cools down. Use ex-
treme care when removing the ra-
diator cap. Wrap a thick towel
around it, and turn it counterclock-
wise slowly to the first stop. Step
back while the pressure is released
from the cooling system. When
you are sure all the pressure has
been released, press down on the
cap, using a thick towel, and con-
tinue turning counterclockwise to
remove it.
WARNING
The electric motor for
the cooling fan may con-
tinue to operate or start
up when the engine is
not running and can
cause serious injury.
Keep hands, clothing and tools
away from the rotating fan blades
of the cooling fan.
