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.
Pull over to a safe location, then
switch the ignition off 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 either 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.

6 –30 Maintenance and Care
Owner Maintenance 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 and LOW
marks on the coolant reservoir when the
engine is cool. Coolant reservoir
Cooling fa nCooling system cap
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. 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.
Do not 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.
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.
If the coolant reservoir is empty or new
coolant is required frequently, consult an
Authorized Mazda Dealer.

7 –28 If Trouble Arises
Overheating If you find a leak or other damage, or if
coolant is still leaking:
Stop the engine and call an Authorized
Mazda Dealer. Coolant reservoir
Cooling fa nCooling system cap
If you find no problems, the engine is
cool, and no leaks are obvious:
Carefully add coolant as required (page
6-29 ).
CAUTION If the engine continues to overheat or
frequently overheats, have the cooling
system inspected. The engine could be
seriously damaged unless repairs are
made. Consult an Authorized Mazda
Dealer.
