ENGINE COOLING SYSTEM
CAUTION: If your engine cooling system overheats, see “Engine
Cooling System Overheating” in Section 3. Continued operation of
the engine even for a short time may result in a fire and the
possibility of personal injury and/or severe vehicle damage.
Your vehicle has an engine coolant recovery system, expansion
bottle and/or a surge tank system. Engine coolant in the system
expands with heat and overflows into the recovery tank. When the
system cools, engine coolant is drawn back into the radiator.
The engine cooling system has been filled at the factory with a
quality engine coolant. It is important to use proper engine coolant to
prevent damage to engine cooling system components. The engine
cooling system is designed to use engine coolant (a mixture of
ethylene glycol, corrosion inhibitors and water) rather than plain water.
The 50/50 engine coolant solution must be used year round to provide:
• Freezing protection down to –31°F (–35°C).
• Boiling protection up to 262°F (128°C).
• Protection against rust and corrosion in the engine cooling system.
• The proper engine coolant temperature for efficient operation and
emission control.
• Proper operation of the engine coolant temperature gauge.
See the Maintenance Schedule in Section 5 to find out when the
engine coolant must be replaced. Note that changing the engine
coolant is needed to replenish the rust inhibitors to make certain that
all parts of the engine cooling system work well.
ENGINE COOLING SYSTEM CARE
Check the engine cooling system at regular intervals, such as during
fuel stops. You usually do not need to remove the radiator cap to
check the engine coolant level.
Look at the see-through engine coolant reserve tank at the back of
the cab without tilting the cab. When the engine is either hot or cold,
engine coolant should be between the “MAX” and “MIN” marks on the
tank.
If the engine coolant level is low, remove the cap on the engine coolant
reserve tank. Add to the reserve tank enough of a 50/50 (48/52 For
Canada) mixture of water and Isuzu Long Life Coolant antifreeze to bring
the level up to the proper mark. Put the cap back on the reserve tank.
NOTICE: When replenishing power steering fluid or flushing the
power steering system, always use ATF Fluid (DEXRON
® - III ).
Failure to use the proper fluid may damage the power steering
system seals and hoses, leading to fluid leakage.
