Engine Coolant
q Inspecting Coolant Level
WARNING
Do not use a match or live flame in the
engine compartment. DO NOT ADD
COOLANT WHEN THE ENGINE IS HOT:
A hot engine is dangerous. If the
engine has been running, parts of the
engine compartment can become
very hot. You could be burned.
Carefully inspect the engine coolant
in the coolant reservoir, but do not
open it.
Turn off the ignition switch and
make sure the fan is not running before
attempting to work near the cooling
fan: Working near the cooling fan when it
is running is dangerous. The fan
could continue running indefinitely
even if the engine has stopped and
the engine compartment temperature
is high. You could be hit by the fan
and seriously injured.
Do not remove either cooling
system cap when the engine and
radiator are hot: When the engine and radiator are
hot, scalding coolant and steam may
shoot out under pressure and cause
serious injury.
NOTE
Changing the coolant should be done by an
Authorized Mazda Dealer.

Inspect the antifreeze protection and
coolant level in the coolant reservoir at
least once a year―at the beginning of the
winter season ―and before traveling
where temperatures may drop below
freezing.
Inspect the condition and connections of
all cooling system and heater hoses.
Replace any that are swollen or
deteriorated.
The coolant should be at full in the
radiator and between the FULL and LOW
marks on the coolant reservoir when the
engine is cool.
If it's at or near LOW, add enough coolant
to the coolant reservoir to provide
freezing and corrosion protection and to
bring the level to FULL.
CAUTION
Ø Radiator coolant will damage
paint.
Rinse it off quickly if spilled.
Ø Use only soft (demineralized)
water in the coolant mixture.
Water that contains minerals will
cut down on the coolant's
effectiveness.
Ø Don't add only water. Always add
a proper coolant mixture.
Ø The engine has aluminum parts
and must be protected by an
ethylene-glycol-based coolant to
prevent corrosion and freezing.
Ø DO NOT USE coolants Containing
Alcohol, methanol, Borate or
Silicate.
These coolants could damage the
cooling system.
Ø DO NOT MIX alcohol or methanol
with the coolant. This could
damage the cooling system.
Ø Don't use a solution that contains
more than 60% antifreeze.
This would reduce effectiveness.

Washer Fluid
qInspecting Washer Fluid Level
WARNING
Use only windshield washer fluid or
plain water in the reservoir:
Using radiator antifreeze as washer
fluid is dangerous. If sprayed on the
windshield, it will dirty the
windshield, affect your visibility, and
could result in an accident.
Using Washer Fluid Without Anti-freeze
Protection in Cold Weather: Operating your vehicle in
temperatures below 4 degrees C (40
degrees F) using washer fluid without
anti-freeze protection is dangerous
as it could cause impaired windshield
vision and result in an accident. In
cold weather, always use washer
fluid with anti-freeze protection.
NOTE
State or local regulations may restrict the use
of volatile organic compounds (VOCs), which
are commonly used as anti-freeze agents in
washer fluid. A washer fluid with limited VOC
content should be used only if it provides
adequate freeze resistance for all regions and
climates in which the vehicle will be operated.
Inspect fluid level in the washer fluid
reservoir; add fluid if necessary.
Use plain water if washer fluid is
unavailable.
But use only washer fluid in cold weather
to prevent it from freezing.
NOTE
Front and rear washer fluid is supplied from
the same reservoir.
