NOTE
Changing the coolant should be done
by an expert repairer, we recommend an
Authorised Mazda Repairer.
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 travelling
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.
Coolant reservoir
If it is at or near LOW, add enough coolant
to the coolant reservoir to provide freezing
and corrosion protection and to bring the
level to FULL.
Securely tighten the coolant reservoir tank
cap after adding coolant.

Owner Maintenance
CAUTION
Radiator coolant will damage paint.
Rinse it off quickly if spilled.
Use only soft (demineralised) water
in the coolant mixture. Water that
contains minerals will cut down on
the coolant's effectiveness.
Do not add only water. Always add a
proper coolant mixture.
The engine has aluminium 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.
Do not use a solution that contains
more than 60% antifreeze.
This would reduce effectiveness.
If the "FL22" mark is shown on or
near the cooling system cap, use
of FL-22 is recommended when
replacing engine coolant. Using
engine coolant other than FL-22 may
cause serious damage to the engine
and cooling system.
