Engine Coolant
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 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 or F and MIN or L marks on the coolant reservoir when the engine is cool.
Without turbocharger
With turbocharger
If it's at or near MIN or L, add enough coolant to the coolant reservoir to provide freezing and corrosion protection and to bring the level to MAX or F.
CAUTION:
Radiator coolant will damage
paint.
Rinse it off quickly if spilled.
Use only soft (demineralized)
water in the coolant mixture.
Water that contains minerals will cut down on the coolant's effectiveness.
Don't add only water. Always add
a proper coolant mixture.
The engine has aluminum parts
and must be protected by an
ethylene-glycol-based coolant to
prevent corrosion and freezing.
DO NOT USE coolants Containing
Alcohol, methanol, Borate or
Silicate.
These coolants could damage the cooling system.
DO NOT MIX alcohol or methanol
with the coolant. This could
damage the cooling system.
Don't use a solution that contains
more than 60% antifreeze.
This would reduce effectiveness.
NOTE:
If the “FL22” mark is shown on or near the
cooling system cap, use FL22 type engine
coolant. If engine coolant other than FL22
type is used, the engine coolant must be
replaced earlier than the specified replacement
interval indicated in the scheduled
maintenance.
If the coolant reservoir is empty or new coolant is required frequently, consult an Authorized Mazda Dealer.
