Mazda 2005 6 SPORTS SEDAN - Manual (Page 264)

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 or F and
LOW or L marks on the coolant reservoir
when the engine is cool.
2.3-liter engine
3.0-liter engine
If it's at or near LOW or L, add enough
coolant to the coolant reservoir to provide
freezing and corrosion protection and to
bring the level to FULL or F.
CAUTION
Radiator coolant will damage paint.
Rinse it off quickly if spilled.
If the coolant reservoir is empty or new
coolant is required frequently, consult an
Authorized Mazda Dealer.
qChanging Coolant
Change coolant according to Scheduled
Maintenance (page 8-3).
CAUTION
l Use only soft (demineralized) water
in the coolant mixture. Water that
contains minerals will cut down on
the coolant's effectiveness.
l Don't add only water. Always add a
proper coolant mixture.
l The engine has aluminum parts and
must be protected by an ethylene-
glycol-based coolant to prevent
corrosion and freezing.
l DO NOT USE coolants Containing
Alcohol, methanol, Borate or
Silicate.
These coolants could damage the
cooling system.
l DO NOT MIX alcohol or methanol
with the coolant. This could damage
the cooling system.
l Don't use a solution that contains
more than 60 % antifreeze.
This would reduce effectiveness.
