Engine Coolant
qInspecting Coolant Level
WARNING
Hot Engine:
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.
Do not use a match or live flame in the
engine compartment. DO NOT ADD
COOLANT WHEN THE ENGINE IS
HOT.
Electrical Fan and Engine
Inspection:
Working near the electrical cooling
fan when it is running is dangerous.
You could be hit by the fan and
seriously injured. Turn off the ignition
switch and make sure the fan is not
running before attempting to work
near the electrical cooling fan.
Cooling System Cap:
When the engine and radiator are hot,
scalding coolant and steam may shoot
out under pressure and cause serious
injury. Don't remove the cooling
system cap when the engine and
radiator are hot.
NOTE
Once the engine coolant exceeds a
preset temperature, an electrical cooling
fan turns on. It will continue running
for about 10 minutes after the ignition
switch is turned to off.
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 F and L marks
on the coolant reservoir when the engine
is cool.
If it's at or near L, add enough coolant to
the coolant reservoir to provide freezing
and corrosion protection and to bring the
level to 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
lUse only soft (demineralized) water
in the coolant mixture. Water that
contains minerals will cut down on
the coolant's effectiveness.
lDon't add only water. Always add a
proper coolant mixture.
lThe engine has aluminum parts and
must be protected by an ethylene-
glycol-based coolant to prevent
corrosion and freezing.
lDO NOT USE coolants Containing
Alcohol, methanol, Borate or
Silicate.
These coolants could damage the
cooling system.
lDO NOT MIX alcohol or methanol
with the coolant. This could damage
the cooling system.
lDon't use a solution that contains
more than 60% antifreeze.
This would reduce effectiveness.
NOTE
If the“FL22”mark is shown on or near
the cooling system cap, use FL22 type
engine coolant. If engine coolant other
than FL22 type is used, the engine
coolant must be replaced earlier than
the specified replacement interval
indicated in the scheduled maintenance
(page 8-3).

To change coolant
WARNING
Removing the Cooling System Cap:
Removing the cooling system cap
while the engine is running or hot is
dangerous. This might lead to cooling
system and engine damage and could
result in serious injury from escaping
hot coolant or steam. Turn off the
engine and wait until it's cool. Even
then, be very careful when removing
the cap. Wrap a thick cloth around the
cap and slowly turn it
counterclockwise to the first stop.
Step back while the pressure escapes.
When you're sure all the pressure is
gone, press down on the cap―still
using a cloth―turn the cap, and
remove it.
1. Make sure the engine is not running
and it has cooled.
2. Remove the cooling system cap.

3. Remove the radiator drain plug and
drain the coolant into a suitable
container. Properly dispose of the used
coolant.4. Flush out the system with running
water.
5. Drain the system completely. Insert and
tighten the plug. Add as much
ethylene-glycol-based coolant mixture
and water as necessary to provide
freezing and corrosion protection.
6. In extremely cold climates, add the
mixture percentage recommended in
the coolant mixture percentage table.
7. Run the engine at idle with the cooling
system cap off. Slowly add additional
coolant if necessary.
8. At this point, wait until the engine
reaches normal operating temperature;
then depress the accelerator two or
three times. Add more coolant, if
necessary, until the system is full.
9. Install the cooling system cap. Inspect
all connections for leaks. Inspect the
level in the coolant reservoir one more
time and verify that the coolant level is
between the F and L marks.
