Overheating
If the temperature gauge indicates
overheating, you experience power loss,
or you hear a loud knocking or pinging
noise, the engine is probably too hot.
If this happens:
1. Drive safely to the side of the road and park off the right-of-way.
2. Put a vehicle with an automatic transaxle in park (P), a manual
transaxle in neutral.
Apply the parking brake.
3. Turn off the air conditioner. 4. Check whether coolant or steam is
escaping from under the hood or from
the engine compartment.
If steam is coming from the engine
compartment: Don ’t go near the front
of the vehicle. Stop the engine. Then
turn the ignition switch to the ON
position without starting the engine.
The radiator cooling fans will start to
cool the engine.
If neither coolant nor steam is
escaping: Open the hood and idle the
engine until it cools. If this doesn ’t
lower the temperature, stop the engine
and let it cool.
5. Check the coolant level. If it’ s low, look for leaks in the radiator
hoses and connections, heater hoses
and connections, radiator, and water
pump.
If you find a leak or other damage, or if
coolant is still leaking, stop the engine
and call an Authorized Mazda Dealer.
Overheating
Steam from Overheated Engine:Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you. Open the hood
ONLY after steam is no longer
escaping from the engine.

Overheating
Form No. 8Q50-EA-01G
If you find no problems, the engine is
cool, and no leaks are obvious, carefully
add coolant as required (page 8-13).
Cooling System Caps:When the engine and radiator are
hot, scalding coolant and steam may
shoot out under pressure and cause
serious injury. Don’t remove either
cooling system cap when the engine
and radiator are hot.
If the engine continues to overheat or
frequently overheats, have the cooling
system inspected. The engine could be
seriously damaged unless repairs are
made.

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 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.
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).
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.
WARNING
2.0-liter engine
2.5-liter engine
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.

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.
9. After the engine has cooled, remove the cooling system cap and inspect the
coolant level. If it ’s low, repeat steps 5
to 8.
Because this procedure requires technical
expertise, we recommend that it be done
by an Authorized Mazda Dealer.





Inspecting Brake/Clutch Fluid
Level
The brakes and clutch draw fluid from the
same reservoir.
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 and clutch
linings. If it is excessively low, have the
brake/clutch system inspected by an
Authorized Mazda Dealer.
NOTE
Mixing green coolant with orange
coolant could decrease the service life
expectancy of the coolant. Use only
genuine Mazda orange colored or
equivalent coolant.

Yo u r M a z d a’s headlights have replaceable
halogen bulbs.




Replacing a Headlight Bulb
1. Make sure the headlight switch is off.
2. Lift the hood and find the bulb in the
rear of the headlight body.
3. 2.5-liter engine Remove the bolts and the coolant
reservoir.
4. Detach the electrical connector from the bulb by squeezing the tabs and
pulling it to the rear.
Handling Halogen Bulbs:When a halogen bulb breaks, it is
dangerous. These bulbs contain
pressurized gas. If one is broken, it
will explode and serious injuries
could be caused by the flying glass.
If the glass portion is touched with
bare hands, body oil could cause the
bulb to overheat and explode when lit.
Never touch the glass portion of the
bulb with your bare hands and always
wear eye protection when handling or
working around halogen bulbs.
Children and Halogen Bulbs:
Playing with a halogen bulb is
dangerous. Serious injuries could be
caused by dropping a halogen bulb or
breaking it some other way.
Always keep halogen bulbs out of the
reach of children.
WARNING
Do not touch the glass surface
