Cooling System
Durable
and
efficient
The
engine
radiator,
Air
To
Air
After
Cooler
(ATAAC),
and hydraulic
oil
cooler
are
packaged
in
a
single
plane.
Aluminum
bar
plate
construction
provides
durability
and
allows
for
higher
heat
transfer
and
superior
corrosion
resistance.
The
standard
cores
feature
8.9
fins
per
inch
(6.5 fins
per
inch
for
the
Waste Handling
Arrangement)
to
allow
debris
to
pass through
and
reduce
plugging
concerns.
The
engine
mounted
demand
fan
provides
engine
cooling
capability
that
is
matched
to
the
ambient
conditions.
Fan speed
is
adapted
to
the
cooling
load
and
reduced
when it is
not
needed
to
save
fuel.
An
optional
manual
reversible
fan
allows
fan
blades
to
be
reversed
manually
to
get
opposite
cooling
air
fl
ow
when
ambient
temperature
is
low.
A
sand
blast
grid
can
be
located
between
radiator
and
fan
and protects
radiator
from
abrasive
materials
and
debris.
The
new
engine
air
filter
strategy
includes
a
cyclone
precleaner that
can
be
cleaned
up
several
times
simply
with pressurized
air.
The
air
conditioner
is
mounted
at
the
rear
of
the
cab
for optimum
ambient
capability.
