If you find no problems, the engine iscool, and no leaks are obvious:
Carefully add coolant as required (page
8-12).
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.

7. Start the engine and inspect around the
drain plug for leaks.
8. Turn it off and wait 5 minutes for the
oil to return to the oil pan.
Check the oil level and fill to the MAX
mark if necessary.
Oil capacity (General reference only,
refer to Specifications section for
capacities.)
NOTE
lThe indicated engine oil capacities
are for general reference purposes
only. When adding or changing oil,
verify the engine oil level with the
oil dipstick.
lUse only specified engine oil (page
10-3).

Because you need a special tool to
retighten the filter, an Authorized Mazda
Dealer should do the work.
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.
Cooling Fan and EngineInspection:
Inspecting the engine with the ignition
switch in the ON position is
dangerous. The cooling fan could turn
on unexpectedly even when the engine
isn't running. You could be seriously
injured by the fan. Turn the ignition
switch off and remove the key from the
ignition switch when you inspect the
engine.
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.

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.
Do not overfill.
If 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 alcohol or methanol
antifreeze. DO 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.

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 (3.0-liter engine) or about
two and a half rotations (2.3-liter
engine).
Step back while the pressure escapes.
When you're sure all the pressure is
gone, press down on the cap (3.0-liter
engine)—still using a cloth—turn
the cap, and remove it.
1. Remove the cooling system cap.

2. Only when the engine is cool, remove
the radiator drain plug and drain the
coolant into a suitable container.
Properly dispose of the used coolant.
3. Flush out the system with running
water.
4. 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.
5. In extremely cold climates, add the
mixture percentage recommended in
the coolant mixture percentage table.
6. Run the engine at idle with the cooling
system cap off. Slowly add additional
coolant if necessary.
7. 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.
8. Install the cooling system cap. Inspect
all connections for leaks. Inspect the
level in the coolant reservoir one more
time.
