Cooling
System
DODGE
Turbo Diesel
During filling, air must be vented
from
the engine coolant
passages.
The air
vents
through the "jiggle pin"
openings
to the
top radiator
hose
and out the
fill
opening.
Note:
Adequate venting is provided for a
fill
rate of 14
liter/minute
[3.5 U.S. gallon/minute].
Caution:
Never use only water for engine coolant. In
tropical climates where antifreeze availability may be
limited, use a corrosion Inhibitor (Cummins Liquid DCA)
to protect the engine cooling
system.
A
mixture of 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].
Caution:
The small holes In the head gasket are
especially
susceptible
to plugging.
Water
will
cause
rust
formation
reducing the
flow
in the smaller
codant
passages.
Caution:
These holes are orifices and their
size
Is
critical.
Do not enlarge the
size
of the orifices. To do so
will
disturb the coolant
flow
and
will
not solve an
overheating problem.
]
Also,
water
used
as a coolant for even a relatively short period
can
result in the cup plugs rusting through allowing the coolant
to leak.
Note:
A sudden
loss
of coolant
from
a heavily loaded engine
can
result in
severe
damage to the
pistons
and cylinder bore.
