Nitrited Extended Life Coolant
For nitrited formulations (NOAT), a heavy-
duty extended life coolant that meets
ASTM D6210 and Caterpillar EC-1
specifications must be used.
The change interval for extended-life
coolant containing nitrite and molybdate is
750,000 miles (1,200,000 km) or 12,000
hours of on-road use (8 years or 15,000
hours of off-highway use) on initial fill with
no extender added. The change interval is
1,000,000 miles (1,600,000 km)/20,000
hours/8 years with an extender addition at
500,000 miles (800,000 km)/10,000
hours/4 years.
Nitrite-Free Extended Life Coolant
Nitrite-free organic acid technology coolant
(OA
T) may be used if it meets DAF 74002.
The change interval for nitrite free coolant
is 600,000 miles (1,000,000 km) or 6
years, with no extender needed. DO NOT
add coolant extender to nitrite-free coolant.
Follow the coolant supplier's drain/flush/fill/
diluting percentages when servicing a
vehicle filled with nitrite-free coolant.
Additional Recommendations:
• Antifreeze is essential for freeze,
overheat, and corrosion protection.
The use of supplemental coolant
additives (SCAs) is not
recommended for extended-life
coolants.

Fuel Recommendations
Precautions and recomendations for
selecting and using the right diesel fuel.
WARNING
The use of diesel fuel that has been
mixed with other
fuels may cause an
explosion. DO NOT mix gasoline, alco-
hol, or gasohol with diesel fuel. Make
sure you know your fuel source and
use the recommended diesel fuel as
indicated in this section of the manual.
Failure to comply may result in death,
personal injury, equipment or property
damage.
CAUTION
Dirt or water in the fuel system can
cause severe damage
to both the fuel
pump and the fuel injectors. Due to the
precise tolerances of diesel injection
systems, it is extremely important that
the fuel be kept clean and free of dirt
or water. Know your fuel source and
make sure all steps are taken for dis-
pensing or using clean fuel in your ve-
hicle. Failure to comply may result in
equipment or property damage.
