engine coolant MAZDA MODEL B4000 CAB PLUS 4 TRUCK 2009 User Guide

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.

1Brake 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 authorized
dealer immediately.2Add the coolant type originally equipped in your vehicle. Do not mix different colors or types of
coolant. Do not use Mazda Extended Life Engine Coolant (orange in color). Refer to Adding
engine coolant, in this chapter.3Service refill capacity is determined by filling the transmission to the bottom of the filler hole with
the vehicle on a level surface.4Automatic transmissions that require MERCON V should only use MERCONV fluid or fluid that
is specified dual usage MERCON/MERCON V. Refer toscheduled maintenance to determine
the correct service interval. Use of any fluid other than the recommended fluid may cause
transmission damage.5Indicates only approximate dry-fill capacity. Some applications may vary based on cooler size and
if equipped with an in-tank cooler. The amount of transmission fluid and fluid level should be set
by the indication on the dipstick’s normal operating range.6Traction-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.
If submerged in water, the rear axle lubricant should be changed.
