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 F and L marks
on the coolant reservoir when the engine
is cool.
If it is at or near L, add enough coolant to
the coolant reservoir to provide freezing
and corrosion protection and to bring the
level to F.
Securely tighten the coolant reservoir tank
cap after adding coolant.
Owner Maintenance
CAUTION
Radiator coolant will damage paint.
l
Rinse it off quickly if spilled.
Use only soft (demineralised) water
l
in the coolant mixture. Water that
contains minerals will cut down on
the coolant's effectiveness.
Do not add only water. Always add a
l
proper coolant mixture.
The engine has aluminium parts and
l
must be protected by an ethylene-
glycol-based coolant to prevent
corrosion and freezing.
DO NOT USE coolants Containing
l
Alcohol, methanol, Borate or
Silicate.
These coolants could damage the
cooling system.
DO NOT MIX alcohol or methanol
l
with the coolant. This could damage
the cooling system.
Do not use a solution that contains
l
more than 60% antifreeze.
This would reduce effectiveness.
