Specifications
Use
antifreeze during all
seasons
to protect the engine cooling
system
from
corrosion
as well as freezing damage.
The
antifreeze
should
be
changed
every
two
years.
A
mixture of 50% water and 50% ethylene-glycol base antifreeze is required for operation of the engine in
temperature environments above -37°C [-34°F]. A mixture of 40% water and 60% antifreeze is recommended for
temperatures below -37°C [-34°F].
Note;
In Tropical climates where antifreeze availability may be limited, use a corrosion inhibitor (Cummins liquid
DCA)
or equivalent to protect the engine cooling
system.
Fuel
Specifications
The
Cummins
Turbo
Diesel
engine has been developed to take advantage of the high energy content and generally
lower
cost
No. 2 Diesel
Fuels.
Experience
has
shown
that
it also operates satisfactorily on No. 1 Diesel
Fuels
or
other
fuels
within
the following
specifications.
