A A dBlue®/DEF
NOTI I CE
R R isk of machine damage.
In the short term, use of the wrong fluid can lead to reduced engine power. In the long term, it can lead to damage
to the SCR-system and the catalyst. Reusing AdBlue®/DEF can lead to contamination. Damages caused by the
use of incorrect fluids will not be covered by the warranty.
Always use fluid specified in ISO 22241-1. Do not reuse drained AdBlue®/DEF.
For reducing nitrogen oxides (NO
X
) the engine is equipped with a selective catalytic reduction (SCR) system.
A diesel exhaust fluid is needed for the process to work. The fluid is called AdBlue® in Europe and Asia, but in
North America it is called Diesel Exhaust Fluid (DEF). When needed, the SCR system warms up the AdBlue®/
DEF-tank and lines.
The fluid is filled in a separate tank, which is completely separated from the fuel tank. AdBlue®/DEF may not be
mixed in the fuel tank and fuel may not be mixed in the AdBlue®/DEF-tank.
AdBlue®/DEF consists of urea crystals (32.5%) and distilled water (67.5%). It is transparent, clear, and has a
slight odour of ammonia. The fluid is not considered to be hazardous, but should still be handled with care. It is
very corrosive, especially with copper and aluminium. For this reason, avoid spilling the fluid on electric cables
and components. Always wipe up any spilled AdBlue®/DEF.
AdBlue®/DEF is not a combustible product. When exposed to high temperatures it will convert to ammonia and
carbon dioxide. The fluid should not come into contact with other chemicals or be mixed with other chemicals.
AdBlue®/DEF is sensitive to both high and low temperatures. It should not be exposed to direct sunlight for any
extended period of time. If the machine is not in use, AdBlue®/DEF starts to freeze at −11 °C (12 °F). The fluid
volume in the tank increases when frozen, this is why it is important to follow the recommended fill volume.
AdBlue®/DEF does not break down or degrade when it freezes. The SCR-system will thaw the fluid so that it
regains its concentration with maintained quality. The machine will work normally during the time that the fluid
melts.
At AdBlue®/DEF temperatures above 20 °C (68 °F) the fluid starts to degrade. Then the fluid gives off ammonia,
which is aggressive to materials such as rubber. At temperatures above 75–80 °C (167–176 °F), ammonia
production increases. However, high temperatures are permitted for a short time.
AdBlue®/DEF should be stored in a cool, dry, and ventilated place. The fluid may not be stored in direct sunlight.
The recommended storage temperature for AdBlue®/DEF is between −11 °C (12 °F) and 25 °C (77 °F). Under
these conditions, storage life is approx. two years. Long-term storage of AdBlue®/DEF at a temperature above
25 °C (77 °F) can reduce the lifetime of the fluid. A short time exposure to higher temperatures has no impact on
the quality.
NO O T T E E !
If the machine is to be parked for an extended period of time (several months) in ambient temperatures above 40
°C (104 °F) the tank must be drained. This to prevent the fluid from having the wrong quality when starting the
machine or that precipitates have a negative impact on the component parts.
NO O T T E E !
If the tank has been drained completely it should be rinsed out with new AdBlue®/DEF before new fluid is filled.
Never reuse old fluid. If distilled water or ordinary water is used when rinsing there is a risk that the system will
generate an alarm due to wrong quality of AdBlue®/DEF.
NO O T T E E !
Water of any kind should not be used when cleaning AdBlue®/DEF system or AdBlue®/DEF components since
there is a risk that even a small amount of water remains in the system after cleaning. The only exceptions allowed
are operations described in the service information made by Volvo.
AdBlue®/DEF is available in plastic container, barrel, IBC, or bulk.
