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.
Ø 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.
Owner Maintenance
If the coolant reservoir is empty or new
coolant is required frequently, consult an
Authorized Mazda Dealer.
