3. Replace the plug tightly after the oil
has thoroughly drained.
4. Fill the engine with new oil to the F
mark on the dipstick.
5. Securely replace the oil-filler cap.
6. Start the engine and inspect around the
drain plug for leaks.
7. Turn it off and wait 5 minutes for the
oil to return to the oil pan.
Check the oil level and fill to the F mark if
necessary.
Oil capacity (General reference only,
refer to Specifications section for
capacities.)
Changing oil filter
Because you need a special tool to
retighten the filter, an Authorized Mazda
Dealer should do the work.

Inspecting Coolant Level
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.
NOTE
•The indicated engine oil capacities
are for general reference purposes
only. When adding or changing oil,
verify the engine oil level with the
oil dipstick.
•Use only specified engine oil (page
10-4).
Engine Coolant
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. Don’t
inspect the coolant system or add
coolant when the engine is hot.

If it’s at or near LOW, add enough coolant
to the coolant reservoir to provide
freezing and corrosion protection and to
bring the level to FULL.
Do not overfill.
If new coolant is required frequently,
consult an Authorized Mazda Dealer.

Changing Coolant
Change coolant according to Scheduled
Maintenance (page 8-3).For mixture percentage:
To change coolant
Radiator coolant will damage paint.
Rinse it off quickly.
•Use only soft (demineralized) water
in the coolant mixture. Water that
contains minerals will cut down on
the coolant’s effectiveness.
•Don’t 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 alcohol or methanol
antifreeze. DO NOT MIX alcohol
or methanol with the coolant. This
could damage the cooling system.
•Don’t use a solution that contains
more than 60 % antifreeze.
This would reduce effectiveness.

Removing the Cooling System Cap:
Removing the cooling system cap or
drain plug 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
or drain plug. Wrap a thick cloth
around it 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. Remove the coolant filler cap.
2. Only when the engine is cool, remove
the radiator drain plug and drain the
coolant into a suitable container.
3. Flush out the system with running
water.
4. Drain the system completely. Insert
and tighten the plug.
5. Fill the system (to the top of the filler
neck) and then the coolant reservoir (to
F) with as much ethylene-glycol-based
coolant and water as necessary to
provide protection from freezing and
corrosion.
In extremely cold climates, add the
amount recommended by the coolant
manufacturer.
6. Reinstall the coolant filler cap.
7. Run the engine at idle for about 10
minutes, then turn it off. If the coolant
level warning light comes on during
this time, turn the engine off.
After turning off the engine, inspect the
drain plug and the water hoses for
leaks.8. After the engine has cooled, remove
the coolant filler cap and inspect the
coolant level. If it’s low, repeat steps 5
to 7.
Because this procedure requires technical
expertise, we recommend that it be done
by an Authorized Mazda Dealer.

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.

Inspecting Brake Fluid Level
Inspect the fluid level in the reservoir
regularly. It should be kept at MAX.
The level normally drops with
accumulated distance, a condition
associated with wear of brake linings. If it
is excessively low, have the brake system
inspected by an Authorized Mazda
Dealer.
