cooling MAZDA MODEL B4000 TRUCK 2005 User Guide

•NEVER decrease the coolant concentration below 40%.
• Engine coolant concentrations above 60% or below 40% will
decrease the freeze protection characteristics of the engine
coolant and may cause engine damage.
Plain water may be added in an emergency, but you mustreplace it with
a 50/50 mixture of engine coolant and distilled water as soon as possible.
Check the coolant level in the reservoir before you drive your vehicle the
next few times (with the engine cool). If necessary, add a 50/50
mixture of engine coolant and distilled water to the engine coolant
reservoir until the coolant level is at the “cold fill level” or within the
“cold fill range” as listed on the reservoir (depending upon application).
Have your dealer check the engine cooling system for leaks if you have
to add more than 1.0 liter (1.0 quart) of engine coolant per month.
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.
If you must remove the coolant cap, follow these steps to avoid 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.
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 Refill capacities in this chapter.

Severe climates
If you drive in extremely cold climates (less than –36° C [–34° F]):
• 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.
What you should know about Limp to Safety cooling (2.3L I4
engines only)
If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily to a place of safety. The distance it can be driven
depends on ambient temperatures, vehicle load and terrain, so when the
engine drops into this mode, it is because the engine has overheated and
you need to take special care to avoid it shutting down.
