Black plate (408,1)
5. Pull it out again and examine the level.The level is normal if it is between
Low or MIN and Full or MAX.
If it is near or below Low or MIN, add
enough oil to bring the level to Full or
MAX.
CAUTION
Do not add engine oil over Full or
MAX. This may cause engine
damage.
6. Make sure the O-ring on the dipstick is positioned properly before reinserting
the dipstick.
Engine Coolant
qInspecting 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.
Switch the ignition to off 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 the 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 MAX and MIN
marks on the coolant reservoir when the
engine is cool.
If it is at or near MIN, add enough coolant
to the coolant reservoir to provide
freezing and corrosion protection and to
bring the level to MAX.
Securely tighten the coolant reservoir tank
cap after adding coolant.
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 Do not 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 Do not use a solution that
contains more than 60%
antifreeze.
This would reduce effectiveness.
