Mazda B2300 Truck (2009 year). Instruction

• 4.0L engine

When the engine is cold, check the level of the engine coolant in the
reservoir.
• The engine coolant should be at the “cold fill level” or within the “cold

fill range” as listed on the engine coolant reservoir (depending upon
application).

• Confirm the color and type of engine coolant before adding, to avoid

mixing incompatible products.

• Refer to scheduled maintenance for service interval schedules.
• Be sure to read and understand Precautions when servicing your

vehicle in 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 to Adding
engine coolant in 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.
• DO NOT USE Extended Life Engine Coolant (orange in color).
• DO NOT USE a DEX-COOL威 engine coolant or an equivalent

engine coolant.

• DO NOT USE alcohol or methanol antifreeze or any engine

coolants mixed with alcohol or methanol antifreeze.

• DO NOT USE supplemental coolant additives in your vehicle.

These additives may harm your engine’s cooling system.

• DO NOT MIX different colors or types of coolant in your

vehicle. Make sure the correct coolant is used.

• DO NOT MIX recycled coolant and conventional coolant

together in your vehicle. Mixing of engine coolants may harm
your engine’s cooling system.

• The 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 is a 50/50 mixture of engine coolant
and distilled water. Add the mixture to the coolant reservoir, when the
engine is cool,

until the appropriate fill level is obtained.

• NEVER increase the coolant concentration above 60%.
• NEVER decrease the coolant concentration below 40%.
• Engine coolant concentrations above 68% 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 be added, in case of
emergency, to reach a vehicle service location. In this instance, the
cooling system must be 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 cap
on the coolant recovery system, add coolant to the coolant recovery
reservoir when the engine is cool. Add the proper mixture of coolant and
water to the “FULL COLD” level. For all other vehicles, which have a
coolant degas system with a pressurized cap, or if it is necessary to
remove the coolant pressure relief cap on the radiator of a vehicle with
an overflow system, follow these steps to add engine coolant.

Note:

The 4.0L V6 engine uses the overflow system, and the 2.3L I4

engine uses 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 possible severe personal injury and damage to
the engine’s cooling system.

Add the proper mixture of coolant and water to the cooling system by
following these steps:

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 “COLD FILL RANGE” or the “FULL COLD”
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
to Checking engine coolant. If the concentration is not 50/50
(protection to –34° F/–36° 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 low
level 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
to Maintenance product specifications and capacities in this chapter.

Fill your engine coolant reservoir as outlined in Adding engine coolant
in this section.

Severe climates

If you drive in extremely cold climates (less than –34°F [–36°C]):
• It may be necessary to increase the coolant concentration

above 50%.

• NEVER increase the coolant concentration above 60%.
• Increased engine coolant concentrations above 60% will

decrease the overheat protection characteristics of the engine
coolant and may cause engine damage.

• Refer 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:
• It is still necessary to maintain the coolant concentration

above 40%.

• NEVER decrease the coolant concentration below 40%.
• Decreased engine coolant concentrations below 40% will

decrease the corrosion protection characteristics of the engine
coolant and may cause engine damage.

• Decreased engine coolant concentrations below 40% will

decrease the freeze protection characteristics of the engine
coolant and may cause engine damage.

• Refer to the chart on the coolant container to ensure the

coolant concentration in your vehicle will provide adequate
protection at the temperatures in which you drive.

Vehicles driven year-round in non-extreme climates should use a 50/50
mixture of engine coolant and distilled water for optimum cooling system
and engine protection.

FUEL FILTER

For fuel filter replacement, see your authorized dealer. Refer to
scheduled maintenance information for the appropriate intervals for
changing the fuel filter.

Replace the fuel filter with an authorized Mazda part. The
customer warranty may be void for any damage to the fuel system
if an authorized Mazda fuel filter is not used.

WHAT YOU SHOULD KNOW ABOUT AUTOMOTIVE FUELS

Important safety precautions

WARNING:

Do not overfill the fuel tank. The pressure in an

overfilled tank may cause leakage and lead to fuel spray and fire.

WARNING:

The fuel system may be under pressure. If the fuel

filler cap is venting vapor or if you hear a hissing sound, wait

until it stops before completely removing the fuel filler cap. Otherwise,
fuel may spray out and injure you or others.

WARNING:

If you do not use the proper fuel filler cap,

excessive vacuum in the fuel tank may damage the fuel system

or cause the fuel cap to disengage in a collision, which may result in
serious personal injury.

WARNING:

Automotive fuels can cause serious injury or death

if misused or mishandled.

2009 B-Series (mbs)

Maintenance and Specifications

253

WARNING:

Gasoline may contain benzene, which is a

cancer-causing agent.

Observe the following guidelines when handling automotive fuel:
• Extinguish all smoking materials

and any open flames before
fueling your vehicle.

• Always turn off the vehicle before

fueling.

• Automotive fuels can be harmful

or fatal if swallowed. Fuel such as gasoline is highly toxic and if
swallowed can cause death or permanent injury. If fuel is swallowed,
call a physician immediately, even if no symptoms are immediately
apparent. The toxic effects of fuel may not be visible for hours.

• Avoid inhaling fuel vapors. Inhaling too much fuel vapor of any kind

can lead to eye and respiratory tract irritation. In severe cases,
excessive or prolonged breathing of fuel vapor can cause serious
illness and permanent injury.

• Avoid getting fuel liquid in your eyes. If fuel is splashed in the eyes,

remove contact lenses (if worn), flush with water for 15 minutes and
seek medical attention. Failure to seek proper medical attention could
lead to permanent injury.

• Fuels can also be harmful if absorbed through the skin. If fuel is

splashed on the skin and/or clothing, promptly remove contaminated
clothing and wash skin thoroughly with soap and water. Repeated or
prolonged skin contact with fuel liquid or vapor causes skin irritation.

• Be particularly careful if you are taking “Antabuse” or other forms of

disulfiram for the treatment of alcoholism. Breathing gasoline vapors,
or skin contact could cause an adverse reaction. In sensitive
individuals, serious personal injury or sickness may result. If fuel is
splashed on the skin, promptly wash skin thoroughly with soap and
water. Consult a physician immediately if you experience an adverse
reaction.

WARNING:

When refueling always shut the engine off and

never allow sparks or open flames near the filler neck. Never

smoke while refueling. Fuel vapor is extremely hazardous under certain
conditions. Care should be taken to avoid inhaling excess fumes.

WARNING:

The flow of fuel through a fuel pump nozzle can

produce static electricity, which can cause a fire if fuel is

pumped into an ungrounded fuel container.

Use the following guidelines to avoid electrostatic charge build-up when
filling an ungrounded fuel container:
• Place approved fuel container on

the ground.

• DO NOT fill a fuel container while

it is in the vehicle (including the
cargo area/pickup bed).

• Keep the fuel pump nozzle in contact with the fuel container while

filling.

• DO NOT use a device that would hold the fuel pump handle in the fill

position.

Fuel Filler Cap

Your fuel tank filler cap has an indexed design with a 1/4 turn on/off
feature.

When fueling your vehicle:

1. Turn the engine off.

2. Carefully turn the filler cap counterclockwise 1/4 of a turn to remove

it.

3. Pull to remove the cap from the fuel filler pipe.

4. To install the cap, align the tabs on the cap with the notches on the

filler pipe.

5. Turn the filler cap clockwise 1/4 of a turn until it clicks at least once.

If the check fuel cap light

or a “check fuel cap” message comes on,

the fuel filler cap may not be properly installed. The light or message can
come on after several driving events after you’ve refueled your vehicle.

At the next opportunity, safely pull off of the road, remove the fuel filler
cap, align the cap properly and reinstall it. The check fuel cap

light

or “check fuel cap” message may not reset immediately; it may

take several driving cycles for the check fuel cap light

or “check fuel

cap” message to turn off. A driving cycle consists of an engine start-up
(after four or more hours with the engine off) followed by city and
highway driving.

Maintenance and Specifications

255

Continuing to drive with the check fuel cap light

or “check fuel cap”

message on may cause the

light to turn on as well.

If you must replace the fuel filler cap, replace it with a fuel filler
cap that is designed for your vehicle. The warranty may be void
for any damage to the fuel tank or fuel system if the correct
genuine Mazda or other certified fuel filler cap is not used.

WARNING:

The fuel system may be under pressure. If the fuel

filler cap is venting vapor or if you hear a hissing sound, wait

until it stops before completely removing the fuel filler cap. Otherwise,
fuel may spray out and injure you or others.

WARNING:

If you do not use the proper fuel filler cap,

excessive vacuum in the fuel tank may damage the fuel system

or cause the fuel cap to disengage in a collision, which may result in
personal injury.

Choosing the right fuel

Use only UNLEADED fuel or UNLEADED fuel blended with a maximum
of 10% ethanol. Do not use fuel ethanol (E85), diesel, methanol, leaded
fuel or any other fuel. The use of leaded fuel is prohibited by law and
could damage your vehicle.

Your vehicle was not designed to use fuel or fuel additives with metallic
compounds, including manganese-based additives.

Note:

Use of any fuel other than those recommended may cause

powertrain damage, a loss of vehicle performance, and repairs may not
be covered under warranty.

Cleaner air

Mazda endorses the use of reformulated “cleaner-burning” gasolines to
improve air quality, per the recommendations in the Choosing the right
fuel section.

2009 B-Series (mbs)
Owners Guide, 1st Printing
USA (fus)

Maintenance and Specifications

256

Octane recommendations

Your vehicle is designed to use
“Regular” unleaded gasoline with a
pump (R+M)/2 octane rating of 87.
We do not recommend the use of
gasolines labeled as “Regular” in
high altitude areas that are sold with octane ratings less than 87.

Do not be concerned if your engine sometimes knocks lightly. However, if
it knocks heavily under most driving conditions while you are using fuel
with the recommended octane rating, see your authorized dealer to
prevent any engine damage.

Fuel quality

If you are experiencing starting, rough idle or hesitation driveability
problems, try a different brand of unleaded gasoline. “Premium”
unleaded gasoline is not recommended for vehicles designed to use
“Regular” unleaded gasoline because it may cause these problems to
become more pronounced. If the problems persist, see your authorized
dealer.

Do not add aftermarket fuel additive products to your fuel tank. It
should not be necessary to add any aftermarket products to your fuel
tank if you continue to use high quality fuel of the recommended octane
rating. These products have not been approved for your engine and
could cause damage to the fuel system. Repairs to correct the effects of
using an aftermarket product in your fuel may not be covered by your
warranty.

Many of the world’s automakers approved the World-Wide Fuel Charter
that recommends gasoline specifications to provide improved
performance and emission control system protection for your vehicle.
Gasolines that meet the World-Wide Fuel Charter should be used when
available. Ask your fuel supplier about gasolines that meet the
World-Wide Fuel Charter.

Running out of fuel

Avoid running out of fuel because this situation may have an adverse
effect on powertrain components.

If you have run out of fuel:
• You may need to cycle the ignition from off to on several times after

refueling to allow the fuel system to pump the fuel from the tank to
the engine. On restarting, cranking time will take a few seconds longer
than normal.

(R+M)/2 METHOD

2009 B-Series (mbs)
Owners Guide, 1st Printing

Maintenance and Specifications

257

• Normally, adding 1 gallon (3.8L) of fuel is enough to restart the

engine. If the vehicle is out of fuel and on a steep grade, more than
1 gallon (3.8L) may be required.

• The Service engine soon

indicator may come on. For more

information on the Service engine soon

indicator, refer to

Warning lights and chimes in the Instrument Cluster chapter.

ESSENTIALS OF GOOD FUEL ECONOMY

Measuring techniques

Your best source of information about actual fuel economy is you, the
driver. You must gather information as accurately and consistently as
possible. Fuel expense, frequency of fill-ups or fuel gauge readings are
NOT accurate as a measure of fuel economy. We do not recommend
taking fuel economy measurements during the first 1,000 miles
(1,600 km) of driving (engine break-in period). You will get a more
accurate measurement after 2,000-3,000 miles (3,000-5,000 km).

Filling the tank

The advertised fuel capacity of the fuel tank on your vehicle is equal to
the rated refill capacity of the fuel tank as listed in the Maintenance
product specifications and capacities section of this chapter.

The advertised capacity is the amount of the indicated capacity and the
empty reserve combined. Indicated capacity is the difference in the
amount of fuel in a full tank and a tank when the fuel gauge indicates
empty. Empty reserve is the small amount of fuel remaining in the fuel
tank after the fuel gauge indicates empty.

The amount of usable fuel in the empty reserve varies and should
not be relied upon to increase driving range. When refueling your
vehicle after the fuel gauge indicates empty, you might not be
able to refuel the full amount of the advertised capacity of the
fuel tank due to the empty reserve still present in the tank.

For consistent results when filling the fuel tank:
• Turn the engine/ignition switch to the off position prior to refueling,

an error in the reading will result if the engine is left running.

• Use the same filling rate setting (low — medium — high) each time

the tank is filled.

• Allow no more than two automatic click-offs when filling.
• Always use fuel with the recommended octane rating.

2009 B-Series (mbs)
Owners Guide, 1st Printing
USA (fus)

Maintenance and Specifications

258

• Use a known quality gasoline, preferably a national brand.
• Use the same side of the same pump and have the vehicle facing the

same direction each time you fill up.

• Have the vehicle loading and distribution the same every time.
Your results will be most accurate if your filling method is consistent.

Calculating fuel economy

1. Fill the fuel tank completely and record the initial odometer reading

(in miles or kilometers).

2. Each time you fill the tank, record the amount of fuel added (in

gallons or liters).

3. After at least three to five tank fill-ups, fill the fuel tank and record

the current odometer reading.

4. Subtract your initial odometer reading from the current odometer

reading.

5. Follow one of the simple calculations in order to determine fuel

economy:

Calculation 1: Divide total miles traveled by total gallons used.

Calculation 2: Multiply liters used by 100, then divide by total
kilometers traveled.

Keep a record for at least one month and record the type of driving (city
or highway). This will provide an accurate estimate of the vehicle’s fuel
economy under current driving conditions. Additionally, keeping records
during summer and winter will show how temperature impacts fuel
economy. In general, lower temperatures give lower fuel economy.

Driving style — good driving and fuel economy habits

Give consideration to the lists that follow and you may be able to change
a number of variables and improve your fuel economy.

Habits
• Smooth, moderate operation can yield up to 10% savings in fuel.
• Steady speeds without stopping will usually give the best fuel

economy.

• Idling for long periods of time (greater than one minute) may waste

fuel.

• Anticipate stopping; slowing down may eliminate the need to stop.

2009 B-Series (mbs)

USA (fus)

Maintenance and Specifications

259

• Sudden or hard accelerations may reduce fuel economy.
• Slow down gradually.
• Driving at reasonable speeds (traveling at 55 mph [88 km/h] uses 15%

less fuel than traveling at 65 mph [105 km/h]).

• Revving the engine before turning it off may reduce fuel economy.
• Using the air conditioner or defroster may reduce fuel economy.
• You may want to turn off the speed control in hilly terrain if

unnecessary shifting between fourth and fifth gear occurs.
Unnecessary shifting of this type could result in reduced fuel
economy.

• Warming up a vehicle on cold mornings is not required and may

reduce fuel economy.

• Resting your foot on the brake pedal while driving may reduce fuel

economy.

• Combine errands and minimize stop-and-go driving.
Maintenance
• Keep tires properly inflated and use only recommended size.
• Operating a vehicle with the wheels out of alignment will reduce fuel

economy.

• Use recommended engine oil. Refer to the Maintenance product

specifications and capacities section of this chapter.

• Perform all regularly scheduled maintenance items. Follow the

recommended maintenance schedule and owner maintenance checks
found in scheduled maintenance.

Conditions
• Heavily loading a vehicle or towing a trailer may reduce fuel economy

at any speed.

• Carrying unnecessary weight may reduce fuel economy (approximately

1 mpg [0.4 km/L] is lost for every 400 lb [180 kg] of weight carried).

• Adding certain accessories to your vehicle (for example bug

deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.

• Using fuel blended with alcohol may lower fuel economy.
• Fuel economy may decrease with lower temperatures during the first

8–10 miles (12–16 km) of driving.

2009 B-Series (mbs)
Owners Guide, 1st Printing
USA (fus)

Maintenance and Specifications

260

• Driving on flat terrain offers improved fuel economy as compared to

driving on hilly terrain.

• Transmissions give their best fuel economy when operated in the top

cruise gear and with steady pressure on the gas pedal.

• Four-wheel-drive operation (if equipped) is less fuel efficient than

two-wheel-drive operation.

• Close windows for high speed driving.

EPA fuel economy estimates

Every new vehicle should have a window sticker containing EPA fuel
economy estimates. Contact your authorized dealer if the window sticker
is not supplied with your vehicle. The EPA fuel economy estimates
should be your guide for the fuel economy comparisons with other
vehicles. Your fuel economy may vary depending upon the method of
operation and conditions.

EMISSION CONTROL SYSTEM

Your vehicle is equipped with various emission control components and a
catalytic converter which will enable your vehicle to comply with
applicable exhaust emission standards. To make sure that the catalytic
converter and other emission control components continue to work
properly:
• Use only the specified fuel listed.
• Avoid running out of fuel.
• Do not turn off the ignition while your vehicle is moving, especially at

high speeds.

• Have the items listed in the scheduled maintenance section

performed according to the specified schedule.

The scheduled maintenance items listed in the scheduled maintenance
section are essential to the life and performance of your vehicle and to
its emissions system.

If other than Mazda authorized parts are used for maintenance
replacements or for service of components affecting emission control,
such non-Mazda parts should be equivalent to genuine Mazda parts in
performance and durability.

WARNING:

Do not park, idle, or drive your vehicle in dry grass

or other dry ground cover. The emission system heats up the

engine compartment and exhaust system, which can start a fire.

Illumination of the Service engine soon

indicator, charging system

warning light or the temperature warning light, fluid leaks, strange odors,
smoke or loss of engine power, could indicate that the emission control
system is not working properly.

WARNING:

Exhaust leaks may result in entry of harmful and

potentially lethal fumes into the passenger compartment.

Do not make any unauthorized changes to your vehicle or engine. By
law, vehicle owners and anyone who manufactures, repairs, services,
sells, leases, trades vehicles, or supervises a fleet of vehicles are not
permitted to intentionally remove an emission control device or prevent
it from working. Information about your vehicle’s emission system is on
the Vehicle Emission Control Information Decal located on or near the
engine. This decal also lists engine displacement.

Please consult your “Warranty Information” for complete emission
warranty information.

On board diagnostics (OBD-II)

Your vehicle is equipped with a computer that monitors the engine’s
emission control system. This system is commonly known as the On
Board Diagnostics System (OBD-II). The OBD-II system protects the
environment by ensuring that your vehicle continues to meet
government emission standards. The OBD-II system also assists your
authorized dealer in properly servicing your vehicle. When the Service
engine soon

indicator illuminates, the OBD-II system has detected

a malfunction. Temporary malfunctions may cause the Service engine
soon

indicator to illuminate. Examples are:

1. The vehicle has run out of fuel—the engine may misfire or run

poorly.

2. Poor fuel quality or water in the fuel—the engine may misfire or run

poorly.

3. The fuel cap may not have been securely tightened. See Fuel filler

cap in this chapter.

4. Driving through deep water—the electrical system may be wet.

These temporary malfunctions can be corrected by filling the fuel tank
with good quality fuel, properly tightening the fuel cap or letting the
electrical system dry out. After three driving cycles without these or any
other temporary malfunctions present, the Service engine soon

2009 B-Series (mbs)

262

indicator should stay off the next time the engine is started. A driving
cycle consists of a cold engine startup followed by mixed city/highway
driving. No additional vehicle service is required.

If the Service engine soon

indicator remains on, have your vehicle

serviced at the first available opportunity. Although some malfunctions
detected by the OBD-II may not have symptoms that are apparent,
continued driving with the Service engine soon

indicator on can

result in increased emissions, lower fuel economy, reduced engine and
transmission smoothness, and lead to more costly repairs.

Readiness for Inspection/Maintenance (I/M) testing

Some state/provincial and local governments may have
Inspection/Maintenance (I/M) programs to inspect the emission control
equipment on your vehicle. Failure to pass this inspection could prevent
you from getting a vehicle registration. Your vehicle may not pass the I/M
test if the Service engine soon

indicator is on or not working

properly (bulb is burned out), or if the OBD-II system has determined
that some of the emission control systems have not been properly
checked. In this case, the vehicle is considered not ready for I/M testing.

If the Service engine soon

indicator is on or the bulb does not

work, the vehicle may need to be serviced. Refer to the On board
diagnostics (OBD-II) description in this chapter.

If the vehicle’s engine or transmission has just been serviced, or the
battery has recently run down or been replaced, the OBD-II system may
indicate that the vehicle is not ready for I/M testing. To determine if the
vehicle is ready for I/M testing, turn the ignition key to the on position
for 15 seconds without cranking the engine. If the Service engine
soon

indicator blinks eight times, it means that the vehicle is not

ready for I/M testing; if the Service engine soon

indicator stays on

solid, it means that the vehicle is ready for I/M testing.

The OBD-II system is designed to check the emission control system
during normal driving. A complete check may take several days. If the
vehicle is not ready for I/M testing, the following driving cycle consisting
of mixed city and highway driving may be performed:

15 minutes of steady driving on an expressway/highway followed by
20 minutes of stop-and-go driving with at least four 30-second idle
periods.

Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
