²3.0L & 4.0L engines
When the engine is cold, check the level of the engine coolant in the
reservoir.
²The engine coolant should be at the ªcold fill levelº or within the ªcold
fill rangeº as listed on the engine coolant reservoir (depending upon
application).
²Confirm the color and type of engine coolant before adding, to avoid
mixing incompatible products.
²Refer to theservice maintenance sectionfor service interval
schedules.
²Be sure to read and understandPrecautions when servicing your
vehiclein this chapter.
If the engine coolant has not been checked at the recommended interval,
the engine coolant reservoir may become low or empty. If the reservoir is
low or empty, add engine coolant to the reservoir. Refer toAdding
engine coolantin this chapter.
WARNING: Automotive fluids are not interchangeable; do not
use engine coolant, antifreeze or windshield washer fluid
outside of its specified function and vehicle location.

Adding engine coolant
Use only Mazda Genuine Engine Coolant or a premium engine
coolant that meets a Mazda specification.
²DO NOT USE Extended Life Engine Coolant (orange in color).
²DO NOT USE a DEX-COOLtengine coolant or an equivalent
engine coolant.
²DO NOT USE alcohol or methanol antifreeze or any engine
coolants mixed with alcohol or methanol antifreeze.
²DO NOT USE supplemental coolant additives in your vehicle.
These additives may harm your engine's cooling system.
²DO NOT MIX different colors or types of coolant in your
vehicle. Make sure the correct coolant is used.
²DO NOT MIX recycled coolant and conventional coolant
together in your vehicle. Mixing of engine coolants may harm
your engine's cooling system.
²The use of an improper coolant may harm engine and cooling
system components and may void the warranty of your vehicle's
engine cooling system. If you are unsure which type of coolant
your vehicle requires, contact your local authorized dealer.
WARNING: Do not put engine coolant in the windshield washer
fluid reservoir. If engine coolant is sprayed onto the windshield,
it could make it difficult to see through the windshield.
When
adding coolant, make sure it isa50/50 mixtureof engine coolant
and distilledwater. Add the mixture to thecoolant reservoir,when the
engine iscool, until theappropriate fill levelis obtained.
²NEVER increase the coolant concentration above 60%.
²NEVER decrease the coolant concentration below 40%.
²Engine coolant concentrations above 60% or below 40% will
decrease the freeze protection characteristics of the engine
coolant and may cause engine damage.
A large amount of water without engine coolant may beadded, incase of
emergency,to reach a vehicle service location. In this instance, the
cooling system mustbe drained and refilled with a 50/50 mixture of
engine coolant and distilled water as soon as possible. Water alone
(without engine coolant) can cause engine damage from corrosion,
overheating or freezing.

For vehicles with overflow coolant systems with a non-pressurized capon the coolantrecovery system, add coolant to the coolant recoveryreservoirwhen theengineis cool. Add the proper mixtureofcoolant andwater to theªFULL COLDºlevel. For all other vehicles, which have acoolant degas system with a pressurized cap, orif it is necessary toremove thecoolant pressure relief cap on theradiator of a vehicle withan overflow system, follow these steps to addenginecoolant.
Note:The 3.0L and 4.0L V6 engines use the overflow system, and the2.3L I4 engines use the degas system.
WARNING: To avoid scalding hot steam or coolant from being
released from the engine cooling system, never remove the
reservoir cap while the engine is running or hot. Failure to
follow this warning may result in damage to the engine's cooling
system and possible severe personal injury.
1. Before you remove the cap, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the cap. Slowly
turn cap counterclockwise until pressure begins to release.
3. Step back while the pressure releases.
4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
5. Fill the coolant reservoir slowly with the proper coolant mixture (see
above), to within the ªCOLD FILL RANGEº or the ªFULL COLDº
level on the reservoir. If you removed the radiator cap in an overflow
system, fill the radiator until the coolant is visible and radiator is
almost full.
6. Replace the cap. Turn until tightly installed. (Cap must be tightly
installed to prevent coolant loss.)
After any coolant has been added, check the coolant concentration, refer
toChecking engine coolant. If the concentration is not 50/50
(protection to ±34É F/±36É C), drain some coolant and adjust the
concentration. It may take several drains and additions to obtain a 50/50
coolant concentration.
Whenever coolant has been added, the coolant level in the coolant
reservoir should be checked the next few times you drive the vehicle. If
necessary, add enough 50/50 concentration of engine coolant and
distilled water to bring the liquid level to the proper level.
If you have to add more than 1.0 quart (1.0 liter) of engine coolant per
month, have your authorized dealer check the engine cooling system.

Your cooling system may have a leak. Operating an engine with a lowlevel of coolant can result in engine overheating and possible engine
damage.
Recycled engine coolant
Not all coolant recycling processes produce coolant which meets Mazda
specification. Use of a recycled engine coolant which does not meet
Mazda specifications may harm engine and cooling system components.
Always dispose of used automotive fluids in a responsible manner.
Follow your community's regulations and standards for recycling and
disposing of automotive fluids.
Coolant refill capacity
To find out how much fluid your vehicle's cooling system can hold, refer
toRefill capacitiesin this section.
Fill your engine coolant reservoir as outlined inAdding engine coolant
in this section.
Severe climates
If you drive in extremely cold climates (less than ±34É F [±36É C ]):
²It may be necessary to increase the coolant concentration
above 50%.
²NEVER increase the coolant concentration above 60%.
²Increased engine coolant concentrations above 60% will
decrease the overheat protection characteristics of the engine
coolant and may cause engine damage.
²Refer to the chart on the coolant container to ensure the
coolant concentration in your vehicle will provide adequate
freeze protection at the temperatures in which you drive in the
winter months.
If you drive in extremely hot climates:
²It is still necessary to maintain the coolant concentration
above 40%.
²NEVER decrease the coolant concentration below 40%.
²Decreased engine coolant concentrations below 40% will
decrease the corrosion protection characteristics of the engine
coolant and may cause engine damage.

²4.0L V6 engine
Check the power steering fluid. Refer to the service maintenance section
for the service interval schedules. If adding fluid is necessary, use only
MERCONtAT F.
1. Start the engine and let it run until it reaches normal operating
temperature (the engine coolant temperature gauge indicator will be
near the center of the normal area between H and C).
2. While the engine idles, turn the steering wheel left and right several
times.
3. Turn the engine off.
4.If your vehicle is equipped with a 3.0L V6 engine,check the
fluid level on the dipstick. It should be within the FULL HOT range.
Do not add fluid if the level is within this range.
5.If your vehicle is equipped with a 4.0L SOHC V6 or 2.3L I4
engine,check the fluid level in the reservoir. It should be between
the MIN and MAX lines. Do not add fluid if the level is within this
range.
6. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the FULL HOT range. Be sure to put the
dipstick back in the reservoir.

5Traction-Lok axles use 4.75±5.0 pints (2.2±2.4L) of rear axle lubricant.
Add 4 oz. (118 ml) of Additive Friction Modifier meeting Mazda
specifications for complete refill of Traction-Lok axles. Service refill
capacities are determined by filling the rear axle 1/4 inch to 9/16 inch (6
mm to 14 mm) below the bottom of the filler hole.
6Brake fluid will drop slowly as the brakes wear and will rise when
brake components are replaced. Fluid levels below the MAX line that do
not trigger the brake warning light are within the normal operating
range, there is no need to add fluid. If the levels are outside the normal
operating range, the performance of your brake system could be
compromised, seek service from your local
authorized dealer
immediately.
