CAUTION
!
Using oils of viscosity besides
those recommended for specific
temperature ranges could result in
engine damage.Energy conserving oils are
recommended. A chief contribution
they make to fuel economy is reducing
the amount of fuel necessary to
overcome engine friction.

1. Be sure the vehicle is on a level surface.
2. Warm up the engine to normal operating temperature.

But if it’ s near at or below L, add
enough oil to bring the level to F.
CAUTION
!
Don’ t add engine oil over F.
This may cause engine damage.NOTEThe distance between L and F on
the dipstick represents 1.0 L (1.06
US qt, 0.88 Imp qt).

Changing engine oil and filter
Change engine oil and filter according
to Scheduled Maintenance (page
8-3).
Please act responsibly—protect the
environment and take used oil to a
recycling facility. Ask your dealer or a
service station for information.
WARNING
!
Handling Used Engine Oil:Continuous contact with used
engine oil could be dangerous. It
could cause skin cancer. Always
wash with soap and water
immediately after changing oil
and filter.

WARNING
!
Checking or Changing EngineOil:Hot engine oil could be
dangerous. If the engine has been
running, the engine oil becomes
very hot. You could be seriously
burned. Don’ t check or change
the engine oil when the engine is
hot.

3. Replace the plug tightly after theoil 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)
2.0-liter engine:
3.3 L (3.5 US qt, 2.9 Imp qt)
2.5-liter engine: 3.7 L (3.9 US qt, 3.3 Imp qt)
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 8-16).Changing oil filter
Because you need a special tool to
retighten the filter, an Authorized
Mazda Dealer should do the work.

 Engine Coolant
 Inspecting 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. Don’ t inspect the coolant
system or add coolant when the
engine is 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 F and L
marks on the coolant reservoir when
the engine is cool.
083-9C1E
2.5-liter engine
J94A7042_a
2.0-liter engine
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.

Maintenance8-22

083-10AE
Do not overfill.
If new coolant is required frequently,
consult an Authorized Mazda Dealer.
CAUTION
!
Radiator coolant will damage
paint. Rinse it off quickly.NOTEMixing green coolant with orange
coolant could decrease the service
life expentancy of the coolant. Use
only genuine Mazda orange
colored or equivalent coolant.


083-11DE
Changing coolant
Change coolant according to
Scheduled Maintenance (page 8-3).
CAUTION
!
• 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.
CAUTION
!
• 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 percent
antifreeze.
This would reduce
effectiveness.

WARNING
!
Removing the Cooling SystemCap:Removing the cooling system cap
or drain plug while the engine is
running or hot is dangerous. This
might lead to cooling system and
(Continued)
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.

3. With the drain plug loose but notfully removed, flush out the system
with running water.
4. Drain the system completely and retighten the plug. 5. Fill the radiator (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 cooling system cap.
7. Run the engine at idle for about 10 minutes. 8. Then do this:
•Run the engine at 2,500 rpm for
about 5 minutes.
• Increase the engine speed to
3,000 rpm for about 5 seconds
and then release the accelerator.
• Do this 4 or 5 times.
• Make sure the engine
temperature gauge does not
reach the HOT zone.
After turning off the engine, inspect
the drain plug and the water hoses
for leaks.
