coolant reservoir MAZDA MODEL B-SERIES 2008 (in English) User Guide

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-COOLengine 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 3.0L and 4.0L V6 engines use the overflow system, and the
2.3L 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 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
toChecking 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
toMaintenance product specifications and capacitiesin this chapter.
Fill your engine coolant reservoir as outlined inAdding 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.
